[Ganglia-general] ganglia how do i monitor mutiple network interfaces using unicast
Hi, I would to configure my gmond client to monitor multiple unicast network interfaces. I see documentation on monitoring multicast network interfaces but not unicast. Then I would like to view the data as separate graphs per network interface on my ganglia web server which runs gmetad. Any ideas? Thanks! -- What NetFlow Analyzer can do for you?

[Ganglia-general] help with jmxetric configuration with tomcat
Hi I have jmxetric configured with tomcat and it is working properly except
that the jmxetric stats are not showing up on my gmetad ganglia-web
server. Other basic stats show up on the gmetad server that are not
related to jmxetric. I am running gmond on the local machine and gmeatd
ganglia-web on a different server. I want gmond to send all data including
the jmxetric data to the gmetad ganglia-web server.
I have installed jmxetric using the instructions located here
https://github.com/ganglia/jmxetric/blob/master/README
Do I need to change my jmxetric.xml file? Here is the config info.
My catalina_opts string is set to:
export CATALINA_OPTS="$CATALINA_OPTS
-Djava.util.logging.config.file=/tmp/jmxetric-master/etc/logging.properties
-cp /tmp/gmetric4j.jar:/tmp/remotetea-oncrpc.jar:/tmp/jmxetric.jar
-javaagent:/tmp/jmxetric.jar=/tmp/jmxetric-master/etc/jmxetric.xml";
My gmond.conf file is set basically like this with multicast commented out
since I'm using unicast, and the rest of the file being the default setup.
host = web_server is the host name of the server running gmetad ganglia_web
which is where the data is being sent to.
globals {
daemonize = yes
setuid = yes
user = nobody
debug_level = 0
max_udp_msg_len = 1472
mute = no
deaf = no
allow_extra_data = yes
host_dmax = 0 /*secs */
cleanup_threshold = 300 /*secs */
gexec = no
send_metadata_interval = 60 /*secs */
}
udp_send_channel {
host = web_server.com
bind_hostname = yes # Highly recommended, soon to be default.
# This option tells gmond to use a source address
# that resolves to the machine's hostname. Without
# this, the metrics may appear to come from any
# interface and the DNS names associated with
# those IPs will be used to create the RRDs.
# mcast_join = 239.2.11.71
port = 8649
ttl = 1
}
udp_recv_channel {
# mcast_join = 239.2.11.71
port = 8649
# bind = 239.2.11.71
}
Thanks!

[Ganglia-general] ganglia data populating summary graph area instead of host graph area
Hi, I am running the percona mysql script to gather gmetric data and populate ganglia but it's populating the summary instead of the host area. Is there a way to change this? When I list the rrds directory the data is indeed in the summary_info directory instead of the host directory. For some reason the data is not tied to the host. Here is the script and installation info. https://launchpad.net/percona-ganglia-mysql Thanks, Aaron -- ___ Ganglia-general mailing list Ganglia-general@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ganglia-general
Re: [Ganglia-general] ganglia data populating summary graph area instead of host graph area
*update The way I am executing the percona script is with a cron job job on the gmetad/web server which has php. The cron job points to a separate server that has the database on it that I am gathering information from. This is what the installation instructions describe to do. It appears that since the script is executing on the getmetad/web server, it then collects information in the rrds database under the gmetad/web server host name instead of the hostname pointed to in the crontab. I don't have php running on the database server and don't want it there. How do I collect data from the database server and have it put into the correct rrds location when I'm running the php script from a different server?

[Ganglia-general] Help ganglia custom graph
I have a few questions as well regarding ganglia. I have it setup and running on a server and client node. I'm capturing data but want to create a custom graph. I figure json is easiest method but I'm not having any luck. Links from Vladimir Vuksan are mostly broken and outdated so I find nothing to reference. In the ganglia blogs it discusses new features but now how to customize them. I create a json report file in var/www/html/ganglia/graph.d directory but no new graph is displayed. Are there any authorizations or permissions I need to set? What might be a reason it's not being displayed? I also try to create a new view but I get the error 'no graphs defined please add some' but there is no visible button to add a view. I search for a conf.php file on my system but there is none. Where is it supposed to be located? What information do I need to add to it to create a view? It would be great if there was documentation that explained this. I am trying to create a custom graph to display mysql stats. How do I add a metric for mysql so I can add it to a custom json graph? Is there documentation I can reference? Is json or php or gmetric the best method to use to create a custom graph? Do know where I can find some documentation to solve these issues. There seems to be so little available.

Re: [Ganglia-general] Ganglia 4.x architecture planning
On Fri, Mar 28, 2014 at 1:45 AM, Maxime Brugidou maxime.brugi...@gmail.comwrote: I don't understand why all this is necessary. I strongly disagree with the horizontal scalability of mongoDB ( i run a very large mongodb cluster in production in addition to other databases) and would rather suggest a pluggable backend with a simpler default (like text files or maybe postgresql or mysql). I'll just 2nd this opinion. My immediate reaction to the addition of mongo is rejection - my experience with it at scale has been awful on a small scale it always feels like overkill. Further, since the data being served seems like a relatively small dataset it's unclear to me why there cannot be more options. For our use case (which is ~180k metrics) an in-memory datastore for metadata should be more than sufficient assuming it can be re-hydrated from some persistent source which could simply be waiting for a polling interval of gmetad. I have no need for the addition of nagios / rsyslog events. I've never looked at Ganglia as a horizontally scalable system and accepted that because it made things simple. If I need to scale it out I need to partition my grids / clusters. Not understanding what cool new capabilities will result from having a database like Mongo backing the metadata my guess is that I'd stick w/ 3.x for as long as I could and then find another solution.

Is it just used by sysadmins, for example, or does everybody in every development or support team access Ganglia? We've actually fronted ganglia-web w/ another app for organizing the graphs so our demands are likely different than others who use the web UI directly, I simply provided the metric count as a reference for metadata size. In our case many different development teams access ganglia via this web frontend and I understand that this increases demand on gmetad, however I've seen a variety of improvements that can be applied to the existing system to get us beyond the performance requirements we have today. I'm not rejecting the use case some may have for a different solution, I'm just pointing out it doesn't have immediate value to me. -- Twitter: @anichols Blog: http://www.opsbs.com Pro: http://www.linkedin.com/in/anichols -- ___ Ganglia-general mailing list Ganglia-general@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ganglia-general

We have a cluster of nodes running gmond 3.1.7 After a restart of gmond and gmetad they are not reporting all of theirs metrics. They all have the same configuration files (using the supplied gmond.conf, but with cluster and host set as needed.) Some are failing to send their some of their Constant Metrics and Time and String Metrics, and they are also failing to send some of there other metrics (such as CPU). By saying they are failing to send, I mean that these do not appear on the ganglia monitoring page A couple questions / suggestions to start: 1) Are you using unicast or multicast? This changes how gmond/gmetad interact. 2) gmond collects locally and you can look at the collected metrics by connecting to the tcp listener of gmond and looking at the XML. This is a good way to confirm that gmond is collecting and exposing metrics for gmetad to pull. 3) gmetad pulls metrics from gmond in unicast mode, so you want to make sure this process is working correctly if you are using unicast. This is what ultimately puts the metrics into rrds and makes them available to the web UI. If you are using multicast I can't help as much as I don't use it. You need to look at those things and see if you can sort out where your metrics are failing to collect. You can also run gmond gmetad in debug mode and see if there are helpful errors but I'd check the basics above first.

Re: [Ganglia-general] Could ganglia view graphics derivatives
On Tue, Jan 22, 2013 at 1:57 AM, Ivan Tretyakov itretya...@griddynamics.com wrote: Hello! We've some graphs which constantly increasing. It would be more convenient to see it's derivatives. Could ganglia pre-process graphs before displaying? Could ganglia view graphics derivatives? Ganglia does this via a feature in rrdtool to do this but there are some caveats. When a metric is initially created in ganglia (the first time it is seen) the RRD is created for that metric and set to a particular type of COUNTER, GAUGE, DERIVE, etc based on the slope that is passed in the metadata. The type that is selected determines how rrdtool calculates values over time. By default, if no slope is provided, it defaults to GAUGE, which will display literal values - so if you have an increasing metric it'll show that increasing slope you describe. If COUNTER or DERIVE is selected then rrdtool will calculate the delta between each interval and display that delta instead of the literal values - this sounds like what you want. You can either modify whatever is collecting the metrics and sending them to gmond so that they provide the appropriate slope (slope = positive if you want counter behavior) or you can use rrdtool to modify the rrd to be the appropriate type. If you search around the web for examples of how to convert a gauge to counter you'll find some guidance. That said, I've found the counter/derive calculations to not be entirely without problems and so I've been a bigger fan of pre-calculating those deltas before I push metrics into ganglia. This isn't a ganglia problem, it has to do with rrdtool. I find doing it this way produces more consistent graphs and you can avoid spikes (positive and negative) by doing this. When you do this all your metrics are gauges and you never worry about slope.

Re: [Ganglia-general] Gmond forward messages
I don't believe it's designed to work this way. In my experience, only metrics collected by gmond are forwarded. Your ganglia sender for hadoop needs to be configured to know which hosts are your collectors and send to those gmond instances rather than the local instance. Aaron On Mon, Dec 24, 2012 at 9:59 AM, Ivan Tretyakov itretya...@griddynamics.com wrote: Hello! Could you help us please with following issue. We want to implement configuration below: | (hadoop hosts) hadoop daemons --- local gmond | --- | (monitoring server) collector gmond --- gmetad + web | Hadoop daemons sends metrics to local gmond via udp channel. Local gmond receives hadoop metrics and gathers metrics by itself and sends it all to remote collector gmond. Gmetad takes metrics from collector gmond via tcp channel (hadoop's and gathered by gmond). But we could see following problem: Collector gmond receive only metrics gathered by remote gmond and not hadoop metrics. If I connect to local gmond via netcat I could see that it has both metrics including hadoop's and it's uptated. But it not send it to remote gmond, I concluded it by looking into local gmond debug output and by connecting to tcp port to both gmond to check which metrics they have. My question is should gmond work with such configuration like we are expecting, we expect to see all (gmond + hadoop) metrics in the rrd and web interface? If yes it is probably configuration issue or bug? Or such configuration is not supported and to get things work we need to reconfigure hadoop daemons to send metrics to collector gmond?

I believe I have observed this in the past when one host doesn't have the metric indicated - hence an RRD for that host/metric combo is missing. I don't believe those graphs work correctly if only some of the hosts matching the regex have the metric being displayed. Try showing each of the hosts that should match individually to find out which one doesn't work. Alternatively, maybe the host regex is including a different type of host which doesn't have an RRD for the metric you are requesting?

Re: [Ganglia-general] [Ganglia-developers] Adding Holt-Winters databases to existing rrd causes __SummaryInfo__ metric to fail to render on graphs
All, To close this thread out - this appears to have been a problem with the script being used to apply the HW rras. It appears when the script would create the new rrd it would reverse the order of creation for DS[sum] and DS[num] and then import the historical data from the old rrd into the DS[num] column. I manually created a new rrd with the HW params and everything works fine - just no historical data imported. Guess it's time to build a new tool for this - I'd love to hear what others are using to convert RRD's or if they just apply HW from the beginning.

We've been working on a similar ability just using php based reports. Two things additional we wanted to be able to do besides just comparing one time period to the previous: a) Compare two arbitrary time periods. In our case we run performance / load tests want to be able to compare a loadtest run X minutes ago with one run Y minutes ago. The delta between X Y is the timeshift. We can do this for any given interval (1h, 2h, 1d, 1w, etc) b) Rather than just show the two metrics overlayed, we wanted to calculate the % difference between two periods. This becomes more useful in production where we want to know if a particular trend has changes more than N% over some period of time (say post-deployment). Down the road we also want to try to normalize the previous period by averaging multiple previous periods. For example, compare Monday this week w/ the average of the last 3 Monday's. I can pass along a blog post here with more details when I get it written up - but being able to do those two things was pretty crucial to us may be useful to others.

[Ganglia-general] gmetad segfaulting frequently with graphite integration enabled
All, We have setup ganglia 3.3.1, built RPM's from the 3.3.1 tarball, and have it configured to push metrics into graphite. All of this setup is new, we're testing this in our dev environment and have about 80 machines pushing metrics in via gmond. We are using rrdcached with gmetad as well. When we have the gmetad configured to send metrics to a carbon server (graphite) we experience two interesting behaviors: 1) The ganglia web UI is very slow (10-20 seconds) to load the main grid view (we only have one grid). However, it is pretty quick if you are viewing any of the individual clusters or hosts. If we disable sending of metrics to graphite OR we shutdown carbon-cache.py on the graphite server, this latency goes away. 2) The gmetad daemon is segfaulting multiple times per day (sometimes multiple times per hour). Again, when we stop sending metrics to graphite this behavior stops. I haven't tested to see if this stops if carbon-cache.py is down. I have run gmetad in debug mode until the segfault occurred and the last few lines before it died were this, which look like it's sending metrics to graphite: carbon proxy:: x.x.x.x 46 is ready to receive Updating host blah.example.com, metric swap_total Carbon Proxy:: sending 'blah.gmetad.blah.example.com.swap_total 16779884 1331070149 ' to x.x.x.x carbon proxy:: x.x.x.x is ready to receivecarbon proxy:: x.x.x.x is ready to receive Updating host blah.example.com, metric diskstat_sdcc_reads Carbon Proxy:: sending 'blah.gmetad.blah.example.com.diskstat_sdcc_reads 0.00 1331070138 ' to x.x.x.x carbon proxy:: x.x.x.x is ready to receive The segfault looks like this in /var/log/messages: Mar 7 20:11:26 blah kernel: gmetad[18445]: segfault at 0 ip 004071ea sp 7f354f021410 error 4 in gmetad[40+d000] Also interesting is that we get this message in our logs about every minute: Mar 7 20:13:06 blah /usr/sbin/gmetad[19098]: server_thread() -1326024960 unable to write root epilog I'm about to start hooking up gdb to this guy but was wondering if someone is aware of this issue or has suggestions for what might be causing this?

Re: [Ganglia-general] XML errors on webpage. (new user question) XML Parsing Error: no element found

No errors in /var/log/messages. xmllint --valid --noout XML.txt shows no errors when I tested the telnet localhost port outputs directly. I have never worked with XML before. Does the daemon version mismatch a factor in this failure? I'd imagine so. Being a whole major version number off, something significant probably changed between versions. gmond ver 3.0.3 gmetad ver 2.5.7 How did you manage to get different version of the daemons? They come in the same package. -- Aaron Tygart
[Ganglia-general] Can anyone share a windows gmond binary with me?
I've got 150 linux boxes up and running and now I'd like to include my very few windoze boxes as well. Could someone mail me a gmond binary for use on a win2k box? Thanks.

When I try to telnet to localhost from the queen node, I get the xml specs, but the I always get -Connection is closed by foreign host. Is this correct? I have no idea what is wrong with my setup.

[Ganglia-general] connection closed by foreign host
I'm trying to get ganglia working for the first time. I have installed authd gmetad libe gexec After installing the ganglia monitor core, I wanted to test my installation, but my connection is being closed. Any ideas? I thought I may should add the 8649 port for telnet inside of my services file, but I'm not sure what to put in my inetd.conf file.
