If a given metric doesn't receive an update within its last specified tmax (from gmetric --tmax=NN), then the metric will be considered down; if a host receives no metric updates or heartbeats at all within its pre-configured host_tmax (from gmond.conf), _it_ will be considered down. I believe (but do not recall offhand) that all metrics for a down host are considered down, so e.g. if the host tmax is 80 seconds and a given metric has a tmax of 600 seconds, once 80 seconds elapse with no heartbeat or updates both the host and the metric are considered down even though the metric's tmax has not been reached. - Adam -- WatchGuard Dimension instantly turns raw network data into actionable security intelligence.

The gmond "globals" configuration option "host_tmax" controls how long a host can go without a heartbeat before being seen as "down"; it's set to 20 by default, but the value in the config file gets multiplied by 4, so the default timeout is actually 80 seconds. http://manpages.ubuntu.com/manpages/raring/man5/gmond.conf.5.html#contenttoc2 - Adam -- WatchGuard Dimension instantly turns raw network data into actionable security intelligence.

This is still quite confusing to me too and I have not investigated much. I thought an interval less than dmax would keep the host alive, but with dmax=600 and a period of 300s, I sometimes found the hosts "down" for Ganglia.

the things is that i dont know how fust this heartbeat is .. i imagine
that either i should send gmetrics faster than this heartbeat or
increase the time between heartbeats (at this moment it is not clear to
me how this is related to dmax and tmax ... )
is dmax the time-width of the metric value and tmax the heartbeat?
so the cronjob should have an size <= then tmax?

yes, it is APC. Thanks for the script! ( a lot more organized than mine:) )
but i would have a few questions:
1. given tmax of 600 , do you have the cron job at 600 seconds?
2. the T is used to see if the ups is down i imagine.. but why are you
interested in collecting the ping time?
(i chosen to ignore failed devices with -r 1 -t 0.5; also given the
delay of snmpget i take all the list of vars with a single snmpget,
redirect in a file and format the variables from the file)
Thanks a lot for help!!

Hi! Is it possible to post your gmond settings? How did you
solve the problem that the reporting node (where aggregation
gmond sits) will also report the self metrics?
My problem is a little different : i try to make a fake gmond
for gmetric input for UPS/RAID/Switches metrics.
Thanks a lot! Adrian

Re: [Ganglia-general] multiple clusters with just one collector
Hello Adrian,
if the host for which you send gmetrics is not a gmond "client", you need to
also spoof a "heartbeat" metric, else the collector will think the host is down
:
HOST=ups.example.com
IP=$(getent hosts $HOST | cut -d" " -f1)
GMON=/etc/ganglia/gmond.UPS.conf
T=$(ping -qn -c 1 -w 6 $IP | grep rtt | cut -d/ -f 5 | sed s/\\.//)
if [ "$T" ] ; then
gmetric -c $GMON -n ping_time -t uint32 -u us -x 600 -d 7200 -g network -T
"ping avg time" -H -S ${IP}:${HOST} -v ${T}
(your custom gmetrics follow here)
and of course in the gmond.UPS.conf you put your separate "collector" gmond
host and port.
For the collector host, I run separate "client" gmond and multiple "collector"
gmond. The latter have separate config files with no "udp_send_channel", in
this way they don't send to themselves their own host metrics.
I think I posted on the list my "gmondsrv" init.d script last year or so...
mail me if you don't find it.
Cheers,
Sergio

Actually in the meanwhile I managed to make it work. For those who
might want to do the same here's what I did:
· Stop gmond and gmetad, and clean the RRD database in the collector
(I was getting unspecified clusters and cached information so this
was a clean start)
· I have 5 clusters so I've created 5 gmond.conf files -
gmond-cluster1.conf, gmond-cluster2.conf...etc. In these files I've
set up the cluster name, both udp and tcp ports to the same number,
and the hostname in the udp_send_channel to 'localhost'

Is it possible to post your gmond settings? How did you solve the problem that the reporting node (where aggregation gmond sits) will also report the self metrics? My problem is a little different : i try to make a fake gmond for gmetric input for UPS/RAID/Switches metrics. Thanks a lot!

Re: [Ganglia-general] multiple clusters with just one collector
Yes, 8651 and 8652 are reserved ports for gmetad, you can start from port 9000 to avoid this issue :-) Glad that you got it working... are you guys planning to make your monitoring page public? It would be cool if we can reference it somewhere :-) Cheers, Bernard On Fri, Jan 24, 2014 at 12:47 AM, Cristovao Jose Domingues Cordeiro wrote: > Thank you for your replies Bernard and Shekar. > > Actually in the meanwhile I managed to make it work.

Re: [Ganglia-general] multiple clusters with just one collector
Thank you for your replies Bernard and Shekar. Actually in the meanwhile I managed to make it work. For those who might want to do the same here's what I did: · Stop gmond and gmetad, and clean the RRD database in the collector (I was getting unspecified clusters and cached information so this was a clean start) · I have 5 clusters so I've created 5 gmond.conf files - gmond-cluster1.conf, gmond-cluster2.conf...etc. In these files I've set up the cluster name, both udp and tcp ports to the same number, and the hostname in the udp_send_channel to 'localhost' · In gmetad.conf I set up a grid name (not necessary but better to have a cleaner UI) · Still in gmetad.conf I have created 5 data_sources, one for each cluster: data_source "Cluster A" localhost:portA data_source "Cluster B" localhost:portB ... Note that these ports and cluster names match those in the gmond files I've created earlier. I had some problems with the ports, some clusters were not appearing if they were using port 8651 for instance, but I just changed the port and they worked...I am not sure why, I don't think this port numbers are restricted...but well, if someone knows why, tell me please · Then I just daemonized the 5 gmonds like this: # deamon gmond -c /etc/ganglia/gmond-clusterA.conf # . · Finally, I just started gmetad and now it's running fine. To add more clusters I just need to, in this order, daemonized the new gmond for that cluster and restart gmetad. Hope this helps someone in the future ;) Cumprimentos / Best regards, Cristóvão José Domingues Cordeiro From: Bernard Li [bern...@vanhpc.org] Sent: 24 January 2014 04:49 To: Cristovao Jose Domingues Cordeiro Cc: ganglia-general@lists.sourceforge.net Subject: Re: [Ganglia-general] multiple clusters with just one collector Hello: To accomplish what you want to do, I believe you have two options: 1) Run multiple gmonds, on the master collector, each one listening on different ports 2) Have one gmond but have multiple udp_recv_channels listening on different ports It might help if you also post your configuration somewhere and reference it here (eg. pastebin or some such).

Re: [Ganglia-general] multiple clusters with just one collector
Hi Gowtham, thanks but that makes use of two frontends, and I only have one. In that example server B is running in one of the clusters and my clusters have a random number of VM's which only live for a few days, top. My master server needs to be collecting everything from every cluster. I am reading solutions about having several gmonds in the collector, but I am not succeeding.

Re: [Ganglia-general] multiple clusters with just one collector
Hello Cristavo, I think we have a setup similar to what you're trying to do. You do not need multiple gmonds in your headnode, but rather one headnode for each cluster. Try to set it up like this: clusterA including localhost, node1 clusterB including node2, node3 In your gmetad.conf on localhost, use localhost as your data_source for clusterA and node2:8650 as your data_source for clusterB , that should suffice. It works fairly well for us.

[Ganglia-general] multiple clusters with just one collector
Hi, I found some similar posts in this mailing list but unfortunately none can solve my situation. Basically, I want to have just one collector to multiple clusters. As far as I understood I need to have multiple gmonds in my headnode, and so I do. I have in my collector: gmetad.conf: data_source "clusterA" localhost data_source "clusterB" localhost:8650 gmond-clusterA.conf and gmond-clusterB.conf, each one with their ports, hosts and cluster names defined, pointing to localhost. I also issued the daemon: gmond -c gmond-clusterA.conf gmond -c gmond-clusterB.conf But this doesn't work. I end up with my web interface just showing an 'unspecified' cluster and 'clusterA'... not clusterB. Any thoughts? thanks Cumprimentos / Best regards, Cristóvão José Domingues Cordeiro -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.
