Hi,
We have the ganglia monitor core 2.5.2 installed on two clusters (20 and
68 hosts, different subnets, connected via gmond's "trusted_hosts") and
watch it with gmetad/webfrontend 2.5.2 running on a machine which
belongs to one of the two clusters. What we observe now (after
installation of 2.5.2, not before) is that the rrd updates from the
"remote" cluster occur kind of less frequently (3 minute intervals) than
the updates from the cluster where the gmetad machine is a member of.
That shows in the graphs (sort of "blocky" for that cluster) as well as
in the update intervals of the rrd files. The gmetad polling interval is
explicitely set to 15 seconds for both data_sources.
Any ideas why that is?
Thanks & Greetings
It's possible that gmetad is parsing the wrong area of the data_source line
for the polling interval. This would make sense if your remote host IP
starts with 192.168 (etc.) ...
Run gmetad with debug output turned on and check the first 100-200 lines or
so of output.
I just got hit by this today, myself... before releasing 2.5.3, someone
should take a look at the interval-parsing code (which apparently doesn't
accomodate the old syntax) and put a note in the readme/Changelog...
[not that I read the Changelog in this particular case myself :) ]
