Re: [Ganglia-general] stacked graph not working

[Vladimir Vuksan]

Indeed htmlspecialchars will do that however it's not used in 
stacked.php at least not in the Github repo. You could try and comment 
out this line


https://github.com/ganglia/ganglia-web/blob/master/functions.php#L1416

Then look in /tmp for a ganglia-graph file with full invocation to make 
sure that output is somehow not getting encoded.

Hi Vladimir,

Thanks for your quick response.

As I understand, the apostrophe or single quote will be converted to 
** with the PHP function htmlspecialchars because it’s considered 
as a special character. See this: PHP: htmlspecialchars - Manual 
<https://www.php.net/htmlspecialchars>. Later, we can convert it back 
with function htmlspecialchars_decode if needed. I search the folder 
/usr/share/ganglia and find a lot of instances of htmlspecialchars but 
don’t know which one cause this problem. I’m not familiar with Ganglia 
and don’t know how to debug further. This seems to happen in many 
Rocky 8.4 machines, all are fresh installed. The ganglia-web version 
is 3.7.5-40. Could you please provide more advice how to debug this?


Thanks.

Not sure why apostrophe is being replaced with . That's breaking 
the rrdtool invocation. You will need to investigate how to change 
that behavior.

Does anyone know what can cause this? It seems a bug in
stacked.php or relative program, but I’m not familiar with this

By the way, we have been using Ganglia for a long time. It works
perfectly in CentOS 7. But we have to upgrade CentOS 7 since it’s
near end-of-life.

Any help would be appreciated.

Re: [Ganglia-general] Stacked Graphs not working

I believe this is an unrelated issue to stacked.php however still a bug. 
I have fixed it in master. You can apply the change yourself if you wish 
or simply update from master

Hi Vladimir,

Thank you for the quick response.   I made the changes you suggested 
on the github.com page and now it seems to be complaining with a new 
error:

http://ganglia.domain.com/ganglia/?m=load_one=hour=by%20name=4=2

ERROR: Could not make sense out of '0'


I should mention that I've made one change to the conf_default.php 
file.    To make the smaller graphs more readable, I changed the 
following line:


FROM -

    $conf['strip_domainname'] = false;

TO

    $conf['strip_domainname'] = true;

I've also changed my clients gmond.conf file to use the line:

  override_hostname = "hostname of system"

I did this because for my larger clusters of systems having the full 
domain in the dropdown menus was looking messy.


I don't think this affects the stacked graphs, but I wanted to mention 
the changes.


Thanks for all your help.

Cheers,

janet

Re: [Ganglia-general] ganglia working properly but metrics not graphing

[Vladimir Vuksan]

  
  
Does it show metrics as broken images
  or are they altogether missing ?
  
  Are you using rrdcached ?

I move gmetad from one server to another. I can see in the
  rrds directory that all of the metrics are being accumulated
  properly. However, when I try to view them in the web ui, the
  metrics are not being graphed. The web ui launches, load
  values are being updated, the heat map is being updated, boxes
  for all of the servers show up and are color coded based on
  the load, the metrics titles show up in the drop down, but no
  metrics are being graphed. Any help would be appreciated.

Re: [Ganglia-general] Ganglia setup with 100 nodes

[Vladimir Vuksan]

  
  
I don't believe that should be an issue
  but it's puzzling that it just stop working.
  
  Can you try switching to unicast to see if that makes a
  difference. Here is the quickstart document.

  We have a 100 node cluster and
which is monitored by Ganglia .We are facing some issue
on the setup as below.
   
  Here is the details
   
  Three group cluster group created
which is monitored by three multicast IP
   
  APP_CLUS  239.2.11.71  
  10 NODES
  DB_CLUS   239.2.11.72  
  80 NODES
  SUP_CLUS   239.2.11.73   10 NODES
   
  Once I have started the gmond
service in all the 100 nodes ganglia web page will show
all the node status properly .
  After exact 5 mins from DB_CLUS
70 nodes will say dead and critical .But node is up and
runningL .Changed all the
configuration multicast IP everything but result is same
.
   
  If I restarted the gmond in all
the nodes again same issue will come after 5 mins.
   
  Is there any
  limitation in multicast IP or ganglia ? We have a 20 node
  cluster which is working fine without any issues .Only one
  difference between these two setup is 100 node cluster is
  running in DNS and 20 node cluster is with local host
  names.

Re: [Ganglia-general] Fine grained monitoring problem

[Vladimir Vuksan]

  
  
Hi Theofilos,
  
  by default gmetad polls gmonds every 15 seconds and inserts them
  into RRDs. You can attempt to change that by adding the polling
  interval e.g. 1-3 seconds in gmetad.conf. To do so you would add
  it after the grid name e.g.
  
  data_source "my grid" 50 1.3.4.7:8655
  
  sets polling period of 50.
  
  This all said polling period of 1 second may be a bit too
  aggressive depending on the size of your cluster.

Unfortunately we don't have any but it should be pretty easy to build

you may need to install some of the dependencies but it should be pretty

Re: [Ganglia-general] inspect graph and csv export gives 1970-01-01 as timestamp

[Vladimir Vuksan]

Can you append =5 to whatever url you use for CSV export. You may need to 
look in browser dev tools to capture it.

Re: [Ganglia-general] Missing source RPMs for Ganglia gmond and gmetad components

Hi Mahendra,
  
  you should be able to take the Ganglia tarball and build from
  there e.g.
  
  rpmbuild -tb ganglia-3.7.2.tar.gz
  
  should do the trick.

  Hi,

   I'm searching for source RPMs for Ganglia components.
I found only the following two from web.
ganglia-3.7.2-6.fc24.src.rpm
ganglia-web-3.5.4-1.src.rpm  (the latest version was not
found).

I also need the following.

ganglia-gmetad-3.7.2-6.fc24.src.rpm
ganglia-gmond-3.7.2-6.fc24.src.rpm

But above two src RPMs are nowhere on the web.
Could someone please point to the place where I could get it ?

Re: [Ganglia-general] organizing graphs into groups

[Vladimir Vuksan]

Hi Aaron,

Metrics are added to metrics group if you send the proper metric group 
e.g. in gmetric this flag is available

   -g, --group=STRINGGroup(s) of the metric (comma-separated)


As far as adding mySQL summary graphs only to certain hosts you don't 
want to add it to default.json but in host specific override e.g. in 
/var/lib/ganglia-web/conf you would add host_myhostname.domain.com.json 
with following

{
   "excluded_reports": [
 "mem_report"
   ],
   "included_reports": [
 "mysql_report"
   ]
}

This would remove the memory report but include mysql report just for 
this host. You can also do it through the UI assuming you have 
reconfigured auth system not to be read-only and clicking the edit 
optional graphs button.

Vladimir

Re: [Ganglia-general] High SystemCPU usage, low UserCPU usage

[Vladimir Vuksan]

  
  
System CPU is CPU time spent in kernel
  mode. Usually it indicates some type of an I/O issue whether it's
  lots of disk utilization, network utilization, network file
  systems hanging e.g. NFS. You would need to review other metrics.

Hi All,


This isn't a problem with Ganglia, but I was hoping I might
  get a little advice on what I am seeing.  I have a customer
  who is running ls-dyna applications, and he is noticing
  something odd.  He is noticing his jobs being bogged down and
  not running at their full capacity.  He looked at the Ganglia
  web interface and saw that "System CPU" was at 100%, while
  "User CPU" was at like 20%.  What processes does the "System
  CPU" refer to?  What tools can I use to track what might be
  pushing the "System CPU" to 100%?  There are times when the
  "User CPU" goes up to 100%, which is what he wants, but then
  at times it spikes down to 20% ish and the "System CPU" stays
  up around 100%.


Any advice is greatly appreciated.  If you need me to send
  output, I certainly can.  Just let me know what to run.


Please let me know.

  Thanks.

You can alert on process memory size e.g. we have alerts that say if

 I see that we can monitor any process and collect CPU and memory metrics for

 Is it possible to monitor the state of the process (if running - state=Up, if

 I see that CPU and memory metrics are coming independently of the process 
 state, so I can’t use them to calculate the process state.
 I think some “process heartbeat” monitor required. Any ideas?

Are you using rrdcached ? That would be my first recommendation if you

06/18/2015 u 06:26 PM, Aaron Thomas Holt je napisao/la:
 Hello all,
 I have 2 central servers collecting data for ~1500 nodes on a 
 multicast setup. These servers are able to handle the load no problem. 
 These two servers unicast to a third server (which ideally contains a 
 copy of all the rrd's on the first two servers). Unfortunately the 
 third server is unable to keep up and I've found is due to the disk 
 I/O. Server 3 has better hardware specs than the first 2 servers, so 
 that shouldn't be the problem.

 Some information:
 Servers 12 are running gmetad 3.6.0. Running strace on these servers 
 reveals that the rrd files are being left open and written to.
 Server 3 is running gmetad 3.7.1. After running strace on this server 
 I found that every time an update to an rrd file is made the rrd is 
 opened, then written to, then closed.

 I highly suspect the disk I/O bottleneck is due to the rrd's being 
 opened/closed every time a write is needed. Any ideas on why this is 
 happening and how I can fix it?

[Vladimir Vuksan]

Thanks Jack. I have integrated your changes into the installation Wiki.

 Vladimir and all:

 Since it's not easy to setup the env of ganglia webfrontend, I tried 
 to add a trouble-shooting part for the wikipage of ganglia-web as 
 following:

 == Trouble shooting ==

 * you need to copy `/var/www/ganglia2/apache.conf` (Ubuntu/Debian) or 
 `/var/www/html/ganglia2/apache.conf` (CentOS/RHEL) to 
 `/etc/apache2/sites-enabled`.
 * In most cases, you need to modify the above apache.conf to make sure 
 the alias /ganglia refers to `/var/www/ganglia2` (Ubuntu/Debian) or 
 `/var/www/html/gangla2` (CentOS/RHEL) .
 * In most cases, you need to modify 
 `/var/www/ganglia2/conf_default.php` (Ubuntu/Debian) or 
 `/var/www/html/ganglia2` (CentOS/RHEL) to make sure `gweb_confdir` 
 refers to the directory where the directories of `conf` and `dwoo` 
 locate in, such as `/var/lib/ganglia-web` or `/var/lib/ganglia`.
 * Make sure you have the dir of rrds under `gmetad_root`.
 * Make sure the above rrds dir should be owned by the user of `nobody`.

 If you guys think this is not bad, how could I push it into the 
 wikipage? Seems that's not the same process as to submit a patch to 
 the sourcecode.

 Thank you,
 -jack

 Where are the installation instruction to be found?

Re: [Ganglia-general] Gmetad-to-Gmetad connection

[Vladimir Vuksan]

Hi Sergey,

Try setting

scalable on

in gmetad.conf of the second instance. From the stock gmetad.conf

# Scalability mode. If on, we summarize over downstream grids, and respect
# authority tags. If off, we take on 2.5.0-era behavior: we do not wrap 
our output
# in GRID/GRID tags, we ignore all GRID tags we see, and always assume
# we are the authority on data source feeds. This approach does not 
scale to
# large groups of clusters, but is provided for backwards compatibility.
# default: on
# scalable off

I have not used this feature in a long time so not sure how well it 
scales however it's worth a shot.

Does second instance have different interactive and xml ports ?

Vladimir

 I can get all data from the second machine via “#nc machine1 8651”, but when 
 I check RRDS, I don’t see any clusters, only Summary_Data folder.
 Why Gmetad doesn’t write data into RRDS?

[Ganglia-general] Ganglia Graphite integration

[Vladimir Vuksan]

As some of you know Ganglia supports feeding metric directly to Graphite 
via gmetad. I spent some time in last few days trying to resurrect some 
of the old changes I have had to allow Graphite to read RRDs directly

https://github.com/vvuksan/ganglia-misc/tree/master/graphite

I found out that those changes are no longer necessary with latest 
version of Graphite. I have written up a document on how to do it

https://github.com/ganglia/monitor-core/wiki/Ganglia-Graphite

I still prefer using Ganglia web :-) however I have been hearing 
requests to support dashboards like Grafana so this is an easy way to do 
just that.

Vladimir

Re: [Ganglia-general] Configuration problem after failover

[Vladimir Vuksan]

No. Gmetad listens to two ports by default

8651 and 8652

8648 and 8649 are ports for the gmond which gmetad is polling.

 Should I expect to see gmetad listening on ports 8648 and 8649 as well?

Based on the timeout from source

Re: [Ganglia-general] Can't aggregate custom metrics

[Vladimir Vuksan]

  
  
Ayman,
  
  what Ganglia web version are you using?
  
  Another thing to try is append debug=5 to see what rrdtool
  command is being executed. See if you can execute that on the
  command line by hand.

  Hi All,

I've added around 40 custom metrics using gmetric.

I can aggregate graphs on some hosts and can't on others, i
tried everything i know but the graphs images are broken.

I got the error message "The image

But the graphs are working fine on the host page.

I would be thankful if anyone can help me.

Re: [Ganglia-general] collect_every vs gmetad polling?

[Vladimir Vuksan]

  
  
collect_every manages how often gmond
  sends out particular metric to other gmond(s). It is completely
  independent of gmetad.

Hi Brad,


The standard rate of polling interval is 15 second.


If you want to increase it you should define the data
  sources as the following:
data_source 10 "cluster_name" host1
  host2...


10 means the polling interval is 10 seconds for this
  cluster.


Thanks

  Subject: [Ganglia-general] collect_every vs gmetad
polling? 
  
  
  
I'm using ganglia to submit data directly to
  a carbon server with use with Graphite/Grafana.  It works
  great, but I'm having issues understanding granularity of
  the data.  It seems like my data comes in at a rate equal
  to the polling interval I set in the gmetad.conf's
  'data_source' attribute.  The "collect_every" attribute
  seems to do absolutely nothing to influence this rate. 
  What am I missing?
  
  
  Ideally, I'd like gmetad and/or gmond to collect at a
rate much faster than what is sent to the carbon
server.  Is this possible?  For instance, can I collect
my data and cache it at say once every 2 seconds, but
then only send it every few minutes to the carbon
server?
  
  
  Thank you,
  Brad H

Re: [Ganglia-general] Ganglia - gmetric --slope=positive

[Vladimir Vuksan]

  
  
Hi Ayman,
  
  Unfortunately that is not gonna work. The slope=positive works
  well if your polling period is similar to gmetad polling period.
  Gmetad polls for metrics every 15 seconds and since you are
  sending new counter values evey 5 minutes for 4 minutes and 45
  seconds the counter value gmetad is polling stays the same. You
  may be better off calculating differentials yourself.

Re: [Ganglia-general] on metric handler

One of the approaches is to "cache" the

https://github.com/ganglia/gmond_python_modules/blob/master/varnish/python_modules/varnish.py#L50
  
  That will "cache" the info for few seconds.

 Hello everyone,

 I'm facing some problems with a Python module we have to collect the

 must be something related to the threading logic, although I'm not sure.
 With gmond 3.1.0 it works with no problems, but with 3.6 it hangs when
 it reads the first temperature, CPU0 (I ran gmond in debug mode with -d
 10 to check it).

 Does anyone know what is wrong with our code? Do we have to change
 anything in order for gmond version 3.6 to work? Attached is the code
 for the module. Any help is appreciated.

Hello All,
  

  
  
I’m new to the Ganglia scene, but I’ve been working on
installing it as part of a project now. I’ve built the latest
Ganglia software (3.6.1 at time of writing) from source on
CentOS 6.5 and the build seemed to go fine, no major issues that
I saw. I am using multicasting as the send/recv method and have
limited the multicasting to the a cluster’s private network
interface. 
  

  
  
I start up gmond on the aggregator node (which happens to the be
cluster master node) and start up the gmond daemons on the
client machines. I think proceed to start gmetad to view the
metrics via web browser and for the first 3 minutes or so, it
appears Ganglia is working perfectly, getting the correct
numbers and such.  However, after about 3 minutes, the web
interface and gstat command report that all my client nodes are
down. The aggregation node remains active. I’ve been unable to
determine the root cause of this. However, if I restart the
gmond daemon on the aggregator, the client nodes come back for
approximately 3 minutes again before going into the ‘dead’
state?
  

  
  
The configurations are nearly standard with only minor
  changes which seem more like descriptive entries and not
  operational entries. I only changed the cluster{} block. The
  filesystem where gmond is from is common and therefore the
  same configuration file is used for all nodes. I’m not too
  worried about the host{} block to describe location right now.


  
  
Does anybody have any helpful pointers and/or suggestions on
where to look for an issue or a misconfiguration? 
  

  
  
Thanks everyone!

I would definitely consider rrdcached

  3.7.0 which is in testing has some additional performance

this is happening in two completely different (but with

I'm monitoring about 500 VM's (on each headnode),

Re: [Ganglia-general] GMond Server + EC2 using UDP Buffer Overflow

[Vladimir Vuksan]

  
  
IIRC by default gmond will set buffer
  size to 128kB which is insufficient if you are collecting lots of
  metrics. These two commits change the behavior so that you can set
  UDP receive buffer to higher as long as eg. net.core.rmem_max is
  set
  
https://github.com/ganglia/monitor-core/commit/5f5d5cad408db9f688ffef5f29524eae0871a5a7
https://github.com/ganglia/monitor-core/commit/fa8b1bc2e334dc7257f9e7562ddbd6936ca200c2
  
  What I do is set this in sysctl.conf
  
  net.core.rmem_max = 5100
  
  then in my UDP receive channels I do
  
    buffer = 5000
  
  Otherwise as you observed you get UDP recv buffer errors.

Its 3.4.x , but I'm wondering this problem is more the system /

As I see the Recieved Buffer Errors at the system level, so
  even before reaching the GMond server process OS is having
  issue in reading those UDP packets.  I might be missing, but
  please see if it make sense. 


Plus I also need to scale my app which is pushing 4

Re: [Ganglia-general] ganglia-web's RRD flush not working with rrdcached's TCP listener (gmetad 3.7.0)

[Vladimir Vuksan]

  
  
I don't believe there is any code in
  Ganglia web that explicitly flushes it. IIRC rrdcached will flush
  it on demand whenever you try to access an RRD that is cached.
  
  FYI What I did is have rrdcached listen both on TCP and UNIX
  socket e.g. these are my rrdcached options
  
  OPTS=" -t 60 -w 180 -z 180 -F -s ganglia -m 664 -l 127.0.0.1:9998
  -s ganglia -m 777 -P FLUSH,STATS,HELP -l
  unix:/tmp/rrdcached.limited.sock -b /var/lib/ganglia/rrds -B -p
  /var/lib/ganglia/rrdcached.pid"
  
  Then in ganglia web I configured it to use
  
  $conf['rrdcached_socket'] = "unix:/tmp/rrdcached.limited.sock";
  
  Hope that helps.

 It means that the network traffic is about hundreds of Peta-byte per
 second.
 It is impossible for one to have such high network speed.

 This situation just happened on SL6. The gmond version is 3.1.7 from
 epel repository. It was OK on SL5 with same gmond version.

 Here is a screen shot of the status:


 Do you know how to reslove the problem?

Hello,

I am fairly new to Ganglia, and have a problem with Ganglia
3.6.0 / Ganglia Web 3.5.10: In one of my clusters, after I
add approximately 55 hosts, the graphs go blank. I think
it's very similar to http://www.mail-archive.com/ganglia-general%40lists.sourceforge.net/msg07852.html,
but that thread is old and does not seem to have been
resolved.

I have five clusters -- four are small (up to 40 hosts) and
are working fine. The last one, "HPC Cluster", is where I am
having trouble. I start gmond 3-5 servers at a
time and after approximately 55 hosts, the web site starts
showing blackouts. If I add more hosts the blackout becomes
permanent. The blackouts present as follows:

* In the Grid report the number of hosts and cores for akk
clusters is correct and allhosts are marked "up".
* In the Cluster report, the number of cores is correct but
some hosts are marked "down". Actually, most of the time
they're all marked "down".
* In both the Grid report and the Cluster report the graphs
for HPC Cluster are blank.
  
* None of
this affects any of the other clusters.
  

I've read a number of threads and tried to anticipate the
most common questions.

* All servers use NTP and running "date" on all of them
shows they're synchronized to a second or so.
* I do not see the message "illegal attempt to update using
time X when last update time is X".
* I moved gmetad to a bigger box (16 cores, 256 GB RAM,
negligible prior usage). Didn't even increase the number of
hosts I can add before the blackouts start.
  
* All data
sources use the default polling interval, 15 seconds.
* Tried adding the servers in different orders.
* No errors in the logs, no errors of I start gmond and
gmetad with -d.
* I ran "netstat -su" on all boxes, and there were no
packets dropped anywhere.
* I ran "netstat -au" on the gmetad box and "Recv-Q" and
'Send-Q" were always 0.
  * The server
  where gmetad runs has a UDP buffer
  (/proc/sys/net/core/rmem_max) of 4194304.
* I dumped the RRDs and in these blank areas the metrics are
"NaN".
* During blackouts, I tried "telnet gmetad servicing
node port" and always got an immediate and
apparently full response.
* The cluster's gmonds are all multicast and all listen and
send. I tried unicast and I tried a deaf/mute
multicastwithout any improvement.
  


I guess that the fact that none of the other clusters is
impacted means it's not a resources issie. I therefore
assume it's a configuration or architecture issue. I can
post the configuration files of gmetad and gmond, but this
post is pretty long as it is. So, in short:

* I am using one gmetad for all clusters.
* The data source for "HPC Cluster" has 6 nodes servicing it
(n800, n816, n832, n848, n864, n880) and uses port 8650.
  
 I
originally only had two nodes. When the blackouts started, I
added more.
  
* Gmond on
all hosts uses six multicast channels, the same 6 nodes
(n800, n816, n832, n848, n864, n880) on port 8650.
  
 I
originally had a single multicast channel. When the
blackouts started, I added more.
  
* Gmond on
all hosts listens on UDP and TCP on port 8650.

Since none of the other clusters is impected, I could
probably split this cluster in smaller clusters and those
would work, but this will make reporting the full cluster
usage more painful.

Any suggestions or ideas would be welcome.

  Subject: [Ganglia-general] Ganglia 3.6 on OSX 10.9 issue
  
  
  Hi All,
Getting back into ganglia after some time off the grid (and
new job), and having some issues with ganglia 3.6 compiling
on OSX. I have macports installed, and have libconfuse
installed via macports. My configure is as follows:

./configure LDFLAGS="-L/opt/local/lib -L/usr/X11R6/lib
-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks/Python.framework/Versions/2.7/lib/"

CPPFLAGS="-I/opt/local/include -I/usr/X11R6/include"
--with-libapr=/opt/local/bin/apr-1-config
--with-python=/usr/bin/python

Now this does compile fine afaik. The problem is when
attempting to run gmond. I get the following:

Cannot load /usr/local/lib/ganglia/modcpu.so metric module:
dlopen(/usr/local/lib/ganglia/modcpu.so, 10): Symbol not
found: _cpu_steal_func
 Referenced from: /usr/local/lib/ganglia/modcpu.so
 Expected in: flat namespace
in /usr/local/lib/ganglia/modcpu.so


Searching the interwebz gives me no clue here, and I can
find very little reference to cpu_steal outside of the
mod_cpu.c source.

This is on OSX 10.9.1

Thanks in advance

  the customer wants to have those data sets combined into one. In

  Any solution? Ideas?

 If I've understood you property:

 1.-) use the Aggregate Graphs from ganglia's web.
 2.-) create a custom grpah and add it to one host :
 quick google search:


http://sourceforge.net/mailarchive/forum.php?thread_name=503E2A47.6020705%40gmail.comforum_name=ganglia-general

 3.-) as they are RRDs you can mix them using your own script (bash,
 perl, python)

Re: [Ganglia-general] Changing System Name

[Vladimir Vuksan]

gmond will keep IP to hostname mapping until you restart IIRC. If you 
are running ganglia 3.2+ my suggestion is to just use override_hostname.

http://sourceforge.net/apps/trac/ganglia/wiki/override_hostname

It makes things much cleaner.

 Is there a good way for a system name to change in ganglia after data 
 collection has started?

 I've got a few systems that started reporting under ip addresses or 
 whose names have changed after they first started reporting data.

 Unfortunately, those systems are STILL reporting under then OLD system 
 names / ip Addresses even after a complete system name change (in the 
 gmond.conf file, /etc/hosts, DNS, etc.)

 I tried deleting the previous RRD data, but the new data just comes in 
 on top of it.  Where are the names coming from?  It's not nslookup 
 and/or hosts since literally these system names and IP addresses DO 
 NOT EXIST on the network anymore.

 I do have bind_hostname = yes in the udp_send_channel section.

Re: [Ganglia-general] Gaps in data

[Vladimir Vuksan]

Based on your graphs this happens randomly ? It would be interesting to 
see if you cannot connect to gmetad during those times. Stracing gmetad 
and doing

netstat -an | grep 865

may be helpful.

BTW there is a gmetad health checker someone wrote which may alert you to 
this situation early.

 https://ganglia.surfsara.nl/?r=monthcs=ce=m=load_ones=by+namec=LISA+Clusterh=host_regex=max_graphs=0tab=mvn=sh=1z=smallhc=4

 In a previous installation, I was able to get around this by using a RAM 
 filesystem. However, the amount of data now precludes me from doing it. 
 (Previously, the RRD data only took up about 2GB, and it's now about 25GB.)

 I also get spurious spikes, where it looks like the data goes to MAX_FLOAT 
 or something like that.

 I was wondering if anyone has seen either of these behaviors, and if they 
 have suggestions for dealing with them.

 Thanks,
Dave

Re: [Ganglia-general] Making use of metric titles?

[Vladimir Vuksan]

You absolutely can however it may be a bit of coding to get it out. 
Basically titles are part of metric extra data in the output gmond/gmetad 
expose e.g.


METRIC NAME=bytes_out VAL=656.45 TYPE=float UNITS=bytes/sec 
TN=120 TMAX=300 DMAX=0 SLOPE=both

EXTRA_DATA
EXTRA_ELEMENT NAME=GROUP VAL=network/
EXTRA_ELEMENT NAME=DESC VAL=Number of bytes out per second/
EXTRA_ELEMENT NAME=TITLE VAL=Bytes Sent/
/EXTRA_DATA

You'd have to modify either one of the graph.d/ scripts or create your own 
script that uses the mapping.

Is there a way to create a report that makes use of the metric titles?

Background: I have Ganglia installed on AIX. In this specific environment I 
also collect fibrechannel (FC) data as defined in the
conf.d/ibmfc.conf file, where I give the metrics a name, based on the 
attachment to the adapter (disk or tape).
For example:
[...]
 metric {
    name = fcs0_input_requests
    title = fcs0 Disk Read IOs
    value_threshold = 0.001
  }
[...]
  metric {
    name = fcs1_input_requests
    title = fcs1 Tape Read IOs
    value_threshold = 0.001
  }
[...]

Could I use the title information to create aggregrate graphs? (at least for 
host and cluster but perhaps also for the grid).
Or do I have to change the metric definitions?

Re: [Ganglia-general] Dynamic views in the web interface

[Vladimir Vuksan]

I am not very keen on best practices since they are often anything but 
best.


One of the reasons why view definitions were designed in a way that they 
were ie. using JSON was to make it fairly easy to generate those using a 
wide variety of tools from config management systems, shell scripts, etc. 
So you could technically run something every few minutes that looks at the 
list of hosts and generates the proper JSON view.

[Ganglia-general] Monitorama hackathon

[Vladimir Vuksan]

There is monitoring geared conference in Boston on March 28 and 29th 
called Monitorama. Second day will include a hackathon where attendees 
will hack on different open source projects. There are two issues reported 
for Ganglia as an option e.g.

https://github.com/monitorama/hackathon/issues/14
https://github.com/monitorama/hackathon/issues/11

If you have a suggestion of something else you'd like to see please open 
up an issue against a correct Ganglia Github repo in 
https://github.com/ganglia/ then link that issue to issue in

https://github.com/monitorama/hackathon/issues

If you have any questions about the hackathon you could direct them to

Re: [Ganglia-general] Ganglia and Nagios: warning / critical state in check_ganglia_metric.sh

[Vladimir Vuksan]

The way Nagios knows whether something is critical or warning is based on 
the exit code so if you look in chec_ganglia_metric.sh you could change


  WARNING)
echo $RESULT
exit 1;;
  CRITICAL)
echo $RESULT
exit 2;;


to say

  WARNING)
echo $RESULT
exit 1;;
  CRITICAL)
echo $RESULT
exit 1;;

basically change CRITICAL into WARNING exit code. That would be the 
quickest hack.

Based on Ganglia Book, chapter 7, Check a Single Metric on a Specific Host we 
can set a check_command like below:

check_ganglia_metric!load_one!more!5

And it is said that:

The operators specified in the Nagios definitions for the Ganglia plug-
ins always indicate the “critical” state. If you use a notequal operator, it
means that state is critical if the value is not equal.

Now.. I'm trying to set a 'warning' state not critical. And can't find 
out-of-the-box solution - even on the authors

I assume that I should write my own hooks for this. Could you tell me how You

Re: [Ganglia-general] Small NTP time corrections create major network graph effects?

Are you absolutely sure these are NTP related ?

On Fri, 21 Dec 2012, Michael Durket wrote:

 I'm experimenting with Ganglia to see if it's a viable replacement for Zabbix 
 at our site. One of the more troublesome issues I've found is with the 
 network graphs. Occasionally, one of our many hosts will get an NTP time 
 adjustment (usually fractions of a second). When that happens, all of a 
 sudden it looks like our network transferred hundreds of petabytes of data 
 (according to the Network Report graphs).

 I suspect this is somehow related to RRD but I was wondering if anyone had 
 seen this or knows of a workaround. People here expect the graphs to reflect 
 data accurately (something that Zabbix isn't very good at when it's under 
 load) and this kind of behavior is problematic (and could disqualify Ganglia 
 from consideration).

 If this is in fact an RRD issue does anyone know if this kind of thing 
 happens with Graphite and Ganglia?

Re: [Ganglia-general] Question about scaling

[Vladimir Vuksan]

60 seconds is likely the problem. I would leave it at default ie 15. I can 
explain later.

Nicholas,

I have it set to collect every 60 seconds at the moment as per the
gmetad I posted yesterday but even with that, running netstat -ua in
a 1 second watch loop, once Recv-Q pops it is still responding
immediately and the Recv-Q never stays lit, so to speak, for more than
two seconds. In fact even telneting to the port only lights up Recv-Q
for 2 seconds flat.

Hi Mark,

I wouldn't be so quick to dismiss timeouts as the problem. The
0.9751s it took to download and parse ganglia's XML tree refers to
the time it took the PHP web frontend to query the gmetad XML whereas
the timeout's I was referring to occur when the gmetad polls the gmonds
during metric collection every 15 seconds.

My suggestion would be to run netstat -ua in a loop on the head node
and look for a non-zero Recv-Q on UDP port 8649. As soon as you see
it go non-zero telnet to port 8649 on the head node and make note of
how long it takes to respond. If it's any longer than 10 seconds you
will see random hosts down and broken graphs on the ganglia web.

Well things blew up ~184 hosts. The web interface shows a random number

are the problem. A telnet to 8649 produces the XLM immediately. Could
this be the point where I need start using a RAM based partition or
could it be something else. Is sflow so much better I should consider
using it? Would multiple gmond's, say one per rack, and listing them
all in gmetad be a solution? At this point I am not sure of the next
step and I really appreciate the help the list have given me so far.



Hi Mark,

I assume cnode340 is the head node that all ~340 other gmond's send
their data to. If so, you could reduce the amount of redundant
metadata flying around by increasing send_metadata_interval to 120
seconds or
higher.

That is correct, cnode340 is the head node for ganglia. I have
increased the send metadata interval to 120 seconds and have 100
nodes reporting at this point and it seems pretty smooth. I am going to
add the others ~50 at a time.

Also, I suspect that if you telnet to port 8649 on your head node it
will take a while to respond because it's busy processing incoming UDP
metrics. If it takes more than 10 seconds to respond on a regular basis
then gmetad will timeout [1].

So far, with the 100 I have the response is an instant dump of the XML.

Try deploying a recently patched version of gmond [2] to the head node
which is now multi-threaded and see if that fixes the problem. It
starts a separate thread for responding to XML metric requests and
should respond immediately while the main thread is still processing
metrics.

I am running:

gmond 3.4.0
gmetad 3.4.0
Ganglia Web Frontend version 3.5.2

Would I need to patch gmond at this version?

Re: [Ganglia-general] [Ganglia-developers] Adding Holt-Winters databases to existing rrd causes __SummaryInfo__ metric to fail to render on graphs

[Vladimir Vuksan]

I don't have a lot of time to look into it however different between 
SummaryInfo RRDs and other RRDs is that SummaryInfo contains ds[num] which 
is the number of nodes that being summarized. I wonder if that is somehow 
throwing off your script.

I would imagine if you are missing library dependencies rrdtool will not work.

create templates/default/user_header.tpl

/head

{if isset($user_header)}
{include(file=user_header.tpl)}
{/if}

 Subject:        Re: [Ganglia-general] Gaglia Web LOGO  Utilization Heatmap


_



 For the logo, with version 3.5.3 of ganglia-web (and possibly others) you can create 
create templates/default/user_header.tpl
 which gets pulled in by templates/default/header.tpl like so right at the 
start of the body:

 /head
 body style=background-color: #ff; onunload=g_refresh_timer=null
 {if isset($user_header)}
 {include(file=user_header.tpl)}
 {/if}

 Has anyone added their own custom logo, i.e. company logo, to their ganglia 
web?  Are their any instructions on how to do this?

 Also, does anyone know how to change the Utilization Heatmap to a pie chart?


 Thank you.

Re: [Ganglia-general] no graphs displayed but png creation ok

[Vladimir Vuksan]

I am not sure how to make sure this doesn't happen again but please check 
your conf.php and make sure there are no trailing new lines ie. last line 
should be

?

Graphs are getting generated however there is an extra newline that is 
inserted at the top that breaks PNG :-(.
