[Ganglia-general] Ganglia and Nagios: warning / critical state in check_ganglia_metric.sh
Hi, I'm trying to integrate Nagios with Ganglia. I stucked in one place and somehow can't find a solution. 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 webpage http://vuksan.com/linux/nagios_scripts.html I assume that I should write my own hooks for this. Could you tell me how You do It?

Re: [Ganglia-general] Empty graphs appear for remote hosts
Ok so check your gmond.conf and make sure that send_metadata_interval is higher than 0 (60 for instance). From the manual: send_metadata_interval (integer_value in seconds): Establishes the interval at which gmond will send or resend the metadata packets that describe each enabled metric. This directive by default is set to 0, which means that gmond will send the metadata packets only at startup and upon request from other gmond nodes running remotely. If a new machine running gmond is added to a cluster, it needs to announce itself and inform all other nodes of the metrics that it currently supports. In multicast mode, this isn’t a problem, because any node can request the metadata of all other nodes in the cluster. However, in unicast mode, a resend interval must be established. The interval value is the minimum number of seconds between resends. regards, Maciej Lasyk GPG key ID: 4FED49C5 GPG public key: http://maciek.lasyk.info/gpg_maciej_lasyk.asc On Mon, Nov 11, 2013 at 8:52 PM, Stas Oskin stas.os...@gmail.com wrote: On Mon, Nov 11, 2013 at 9:32 PM, Maciej Lasyk mac...@lasyk.info wrote: Multicast or unicast?

Re: [Ganglia-general] some questions about ganglia
Hi, I believe that I'm experiencing deja-vu... ;) Ad1: Users can find easily any metric in gweb. Just use Aggregate graphs or views functions. If for some reason You'd like to completely switch off some graphs you could simply cut not needed metrics o nodes by removing those from /etc/ganglia/gmond.conf. You can also group metrics so users could easily see only those they want (for example in gweb/conf(_default).php - just read this whole file and set things the way it feets your needs. Also remember that you could create your own web template. Ad2: RRDs are greatly configurable regarding to storage needs. Just reconfigure those in /etc/ganglia/gmetad.conf (section: Round-Robin Archives) regards, Maciej Lasyk GPG key ID: 4FED49C5 GPG public key: http://maciek.lasyk.info/gpg_maciej_lasyk.asc On Tue, Nov 12, 2013 at 3:02 AM, 酃點℡ lqs...@foxmail.com wrote: Hi all, I am a user of ganglia.

Is there a way to cut some metrics that user don't care about so that they can easily find the metric they want ? 2. Ganglia stored the data into Round Robin Database, as the time passed by , the file size of rrd storage grown up. So Is their a way just keep half of year data or only one month? if anyone know anything about it , please answer me. Thanks!

Re: [Ganglia-general] gmond's on same multicast port won't communicate at same time
Are you afraid that we could see performance data of the Curiosity? :D
First of all I would really suggest you read the Monitoring with Ganglia
book (2012). It answers many questions and solves major problems.
About your issue:
1. How do you set deaf and mute in gmond nodes?
2. How many listening gmonds (aggregators, hosts with deaf=no) do you
have? (if using multicast than probably by default all gmond hosts are
aggregators)
3. What is the size of the downloaded XML (telnet to gmond aggregator on
port set in tcp_accept_channel)? Does it contain all hosts you monitor
(write XML content to file and grep looking for 'HOST NAME' or smt like
that)
4. Do you have any ACLs set in gmond configuration?
5.
Btw - in the config section you shared you have a white-space in port
number 8 204:
/* You can specify as many udp_recv_channels as you like as well. */
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8 204
bind = 239.2.11.71
}

Being that I work at NASA, I'd rather not put entire files out there with
names of hosts and ports and the like. :) My initial post had in it part
of the gmond config's.
My datasource line in my gmetad.conf file (for this one port) is simply
something like this:
data_source my_name gmond_hostA:8204 gmond_hostB:8204
If there's anything else specifically, just ask and I'll give it (with
names changed to protect the innocent).

I'm still racking my brain with this problem I'm having. I've even
ran
'tcpdump -i any port 8204' on my gmetad server and watched the
traffic when I've got two gmond clients sending out multicast
packets on port 8204 I can see handshaking between my server and *one*
client. The other client via the tcpdump just shows packets being
sent
out - and no replying. On the server gui, I see only the one client
showing up.
I then stop gmond on the client that's 'working' and immediately on my
other client, the tcpdump output changes to handshaking between the
client and server - and the server's tcpdump also then changes to show
the new client (the old one stops). Then eventually on the server
gui I
stop seeing the old client updating (the icon for the host turns that
block of red... 'host down') and my new client shows up like nothing
ever happened.
This mak
es no
sense. I don't believe I've oversubscribed the number of
gmond's on my server (around 150 maybe?). The gmetad server is
running
RHEL 6.2, and my two gmond clients are running RHEL 6.5. The strange
thing is, it appears that only my RHEL 6.5 clients are having this
problem. every other gmond client is either RHEL 5.x or SuSE 11.1
or
11.2.
I've googled this problem til I'm blue in the face, gone back through
the last few years of the ganglia-general mailing list archives as
best
I could with keyword searches, consulted many of my system admin.
co-workers, and even tried using unicast instead of multicast (that
didn't make a difference either). Nothing seems to matter.
There's got to be somebody out there reading this mailing list who's
got
RHEL6.5 gmond clients. Anybody? Please? :)
Thanks,

I'm curious as of what the correct answer would be, but..
We have similar problem (forgive if not, I just scanned through
your
email), and some kind of solution was to use different data_source
(@gmetad) for each of such issues and give them same cluster {

I think this has something to do with multicasts between
switches, but
so far noone has looked into this..
