[Ganglia-general] gmond host no longer collecting data from other nodes
Hello all,
I'm hoping someone can point me in the right direction. After an
upgrade to Red Hat EL 5.6 earlier this week, my gmon collector service
is only showing the localhost and none of the gmon multicast traffic
from the other nodes. I can see the multicast traffic getting to this
server, but 'gstat -a' lists nothing but itself.
It's quite bizarre because my ganglia nodes didn't disappear until
about 24 hours after the upgrade had been completed. I'm at a loss as to
what could have happened. I've verified that selinux is disabled and the
issue persists. IPtables have been disabled (just in case) and it
persists. The gmond.conf file under /etc/ganglia/gmond.conf was copied
back directly from backup *and* known working nodes. Note: the
non-upgraded nodes list all other nodes with a 'gstat -a' correctly.
I'm really at a loss here. Any pointers on where to look are
appreciated. I'm hoping it's something simple I'm stupidly overlooking.
Relevant info below. Thanks in advance!
--gmon multicast traffic is making it to this gmon collector

[Ganglia-general] spoofed metrics from a mute gmond?
Hello everyone, I'm attempting to spoof some metrics using a python module. The module works fine so long as the gmond is not mute, however I'm not interested in host metrics from the local system. This particular gmond instance exists ONLY for the purpose of collecting external custom metrics. If the instance is mute the metric callback function is never invoked at all. Is it possible to spoof metrics with a muted gmond?

[Ganglia-general] Gmetric values should not persist
I have been using gmetric to create rrd data. The problem is that if I have a peak, I keep on getting the same peak value even if the source is not sending any value after a single spike. I used dmax as 50 and my rrd files are getting created by default settings. Could any one suggest a solution.
