So, on your 1 node pool, you get 8 daemon ads but none are published to ganglia. So, either the ads or machine names do not match. You increased the GANGLIAD_VERBOSITY to 10. So, unless /home/condor/condor-8.3.4-x86_64_Ubuntu14-unstripped/etc/condor/ganglia.d/00_default_metrics is empty, you are not matching machine names.

First, make sure that the 00_default_metrics is not empty.

Then, I recommend setting
ÂÂÂ GANGLIA_SEND_DATA_FOR_ALL_HOSTS = true

This setting is used to inject metrics for hosts not being monitored by ganglia (typically windows hosts or other hosts without a local gmond). You may see the HTCondor metrics appear under a different hostname. Whenever the HTCondor gangliad propagates metrics to hosts not monitored by ganglia, it needs to send the heartbeats for those hosts. Sending 0 heartbeats is not in of itself indicative of a problem.

Hopefully, that will get you a little further along. Let us know what you find.

Hello,

I trying to learn how to setup ganglia to monitor a condor pool.

I'm currently working on localhost to make things easier. I configured ganglia and it's working to monitor this 1 node cluster. The default metrics of gmond.conf are working fine and appear on the web frontend, but I'm having trouble to get the condor metrics.

In the GangliaLog I have:

Here are my configs of ganglia:

$condor_config_val -dump |grep -i ganglia

DAEMON_LIST = COLLECTOR MASTER NEGOTIATOR SCHEDD STARTD GANGLIAD

GANGLIA_CONFIG = /etc/ganglia/gmond.conf

GANGLIA_GMETRIC = /usr/bin/gmetric

GANGLIA_GSTAT_COMMAND = gstat --all --mpifile --gmond_ip=localhost --gmond_port=8649

GANGLIA_LIB = libganglia.so

GANGLIA_LIB64_PATH = /lib64,/usr/lib64,/usr/local/lib64

GANGLIA_LIB_PATH = /lib,/usr/lib,/usr/local/lib

GANGLIA_SEND_DATA_FOR_ALL_HOSTS = false

GANGLIAD = $(LIBEXEC)/condor_gangliad

GANGLIAD_INTERVAL = 60

GANGLIAD_LOG = $(LOG)/GangliadLog

GANGLIAD_METRICS_CONFIG_DIR = /home/condor/condor-8.3.4-x86_64_Ubuntu14-unstripped/etc/condor/ganglia.d

GANGLIAD_PER_EXECUTE_NODE_METRICS = true

GANGLIAD_REQUIREMENTS =Â

GANGLIAD_VERBOSITY = 10

MAX_GANGLIAD_LOG = $(MAX_DEFAULT_LOG)

GANGLIAD daemon is running but I think it's not transmitting its monitoring data to ganglia.

Do I have to do something to include the condor default metrics into ganglia?

Well I'm not sure why but I keep getting "Heartbeats sent: 0". I would appreciate some help.

Thanks in advance,

Ricardo Oda
