[Ganglia-general] Running Ganglia, rrdcached on Alma 9 or Rocky 9?
Hi All, Have anyone succeed running Ganglia on a recent Alma or Rocky 9 with system and rrdcached working together? Trying to update our systems monitoring but it is somehow tricky. Any advice much appreciated!

[Ganglia-general] gmond forwarding from one internal network to another?
Hi All,
I think this topic was discussed here; but somehow I am stuck with it
again.
I have a unicast gmond setup on our cluster. There are compute nodes on
192.168, login nodes on 10.x and 192.168 and the Ganglia server on 10.x
only. I want to forward metrics from 192.168 to the server, preferably
without creating custom routing schemes as it might affect other stuff on
the cluster. So I have following setup:
1) Compute node's gmond are deaf and send metrics over 192.168 network
to three of login nodes gmond's. So I have three send channels like this:
udp_send_channel {
bind_hostname = yes
host = 192.168.x1.y1 port = 8649
ttl = 3
}
2) Login nodes receive and send metrics. I want them to receive computes'
metrics over their 192.168 interface and pass metrics to 10.0. network,
where my gmond/gmetad/gweb resides. So their send channel is:
udp_send_channel {
bind_hostname = yes
host = 10.my-gmetad-ip
port = 8649 ttl = 2
}
and they supposed to listen to anything?
udp_recv_channel {
port = 8649
# Size of the UDP buffer. If you are handling lots of metrics you really
# should bump it up to e.g. 10MB or even higher.
buffer = 20971520
}
3) and the gmond of 10.my-gmetad-ip has similar udp_recv_channel config.
Somehow it doesn't work though; telnet to the TCP port on the server,
10.my-gmetad-ip shows that it gives only the metrics from the login nodes
coming from their 10.x interfaces. The login nodes seem to have the
metrics from compute nodes' 192.168.x interface, as telnet shows, but do
not pass these further, somehow.
I check the metrics as follows:
telnet 10.0.0.24 8649 | grep HOST
Could you please suggest, what am I doing wrong in this setup? Is gmond
supposed to forward like this at all? Thank you very much in advance!

[Ganglia-general] How to use procstat metrics in gmond 3.7.0 ?
Hi All,
I am trying to use process statistics metrics defining them in
procstat.pyconf . In some cases this doesn't work. There is nothing
reported; the metric appears in the Ganglia Web interface but is empty.
What I am trying to do is to monitor my Torque server. I have in the
procstat.pyconf now:
param pbs_server {
# pbs_server seem to have PID there
# value = '/var/spool/torque/server_priv/server.lock'
value='/pbs_server/'
}
Could you please suggest how to specify the daemon to monitor in
procstat.pyconf? It seems from the examples, that both PID or process
name cane be specified?
It did not work for me, either with the PID value from server.lock file
(commented out now), or with the string value.
Thank you very much!

One is to split your hosts into separate clusters, and multiple gmetad instances. These could easily be on the same host, but use different disk partitions so there's less IO contention. Dump all of the files into a single location, but use symlinks to distribute them. Get an SSD drive, and use that; it should help a fair bit since the IO is largely small/random. Disable readahead on the device in question. Use tmpfs to store the RRD files, but remember to sync them back to persistent storage periodically (and restore them again at boot-time).

Hi, More specifically, somehow in Ganglia 3.6 a solution posted here previously, gmetric -t uint32 -s zero -n 'cpu_num' -v $NCPUS -u 'CPUs' it doesn't seem to change total number of CPUs or cpu_num of individual nodes, as shown by the Web frontend. Could someone advise please, how to count real cores only? -- Grigory Shamov HPC Analyst, Westgrid/Compute Canada E2-588 EITC Building, University of Manitoba (204) 474-9625 On 14-04-14 9:14 AM, Grigory Shamov grigory.sha...@umanitoba.ca wrote: Hi All, I am sure this has been resolved already, but googling did not bring me an immediate answer for the new Ganglia.
