Hello All,
I have been considering to use ganglia for profiling / monitoring CPU, Load,
Memory and other stats from our infrastructure servers ( around 50 or so ).
These servers are not part of a cluster of any sort and most of these are
application servers. I am interested in data for each machine to be available
for a period of as long as I want in graph mostly accessible via web. From my
reading online I see that Ganglia could be used for this purpose.
I have setup the following:
1. One server ( lets say XXX ) running a GMOND & a GMETAD ( I have also setup
rrdtool, apache, php etc required for web access )
2. Another machine( lets say YYY) running GMOND.
At this point, I have figured out that I need to have the GMOND on YYY
configured to send data to GMETAD on XXX. And was hoping that I would then be
able to see the data slowly appear on XXX and viewable on the web via a Graph.
I haven't been successful yet in getting what I need. Any help or pointer in
the right direction is appreciated. The following are the entries in the
configuration files that I have changed. The rest of the entries in the file
are default.
*******GMOND.conf on YYY*******************
cluster {
name = "APPSERVERS"
owner = "unspecified"
latlong = "unspecified"
url = "unspecified"
}
udp_send_channel {
host = core-dev
port = 8649
ttl = 1
}
udp_recv_channel {
port = 8649
}
******GMOND.conf on XXX**********
cluster {
name = "APPSERVERS"
owner = "unspecified"
latlong = "unspecified"
url = "unspecified"
}
udp_send_channel {
host = core-dev
port = 8649
ttl = 1
}
udp_recv_channel {
port = 8649
}
*********GMETAD.conf************
data_source "APPSERVERS" localhost
gridname "APPGrid"
setuid_username "apache"
I am of the thought that the GMOND on YYY will send communication on port 8649
of XXX. But GMETAD is listening on ports 8651 and 8652.
Now, which one of these ports should the GMOND on YY should be configured for
its UDP send channel?
In my setup, what would be the directory structure I should be seeing under
/var/lib/ganglia/rrds? I currently see the following:

Thanks in advance.
