Re: [Ganglia-general] ganglia data source shown as unspecified
Hi, Managed to solve this issue. The problem was on the first client in the list. Found it with: # telnet localhost 8649 | grep -i "CLUSTER NAME" This client return this output: The fix was in two ways: 1. Changing the order of the clients (the other clients return correct cluster_name), so that client won't be the first in line fix the issue. 2. Restart gmond on that client, fixed the issue on the client (seems like it was a cache issue). Bottom line, the cluster name showed in the WEB GUI was taken from the first client in the list (which was wrong). Hoping it will help to anyone facing this issue in the future.

Server gmetad.conf have many data source defined, each one have a list of many servers. 2. All data source appears correctly on the ganglia portal (grid combo box) except one data source which shown as "unspecified". Still it is showing the clients monitoring correctly. 3. Still, when checking the data source which doesn't appears correctly by its name (instead appears as "unspecified"), can't find anything wrong in the server configuration (gmetad.conf ) or in the clients configuration (gmond.conf), both configuration have the correct data source name. 4. The version we are using is: a. Server side: libganglia-3.4.0-1.x86_64 ganglia-web-3.5.3-1.noarch ganglia-gmond-3.4.0-1.x86_64 ganglia-gmetad-3.4.0-1.x86_64 ganglia-gmond-modules-python-3.4.0-1.x86_64 b.

Re: [Ganglia-general] Problems getting rrdcached working with Ganglia
Hi Keith, Below is our implementation of rrdcached w/RHEL56. We run this script on boot before we start gmetad. When we installed the rrdcached rpm, it created rrdcached group & user entries. The issue is finding the right set of file perms for both gmetad and apache. > # set ganglia rrd perms for root > rrds_dir=/var/lib/ganglia2/rrds > chown -R nobody $rrds_dir > chgrp -R root $rrds_dir > > # start rrd as group "rrdcached" > /usr/bin/rrdcached -z 60 \ > -s rrdcached -l unix:/var/rrdtool/rrdcached/rrdcached.sock \ > -s rrdcached -P FLUSH,STATS,HELP -l > unix:/var/rrdtool/rrdcached/rrdcached.limited.sock \ > -b $rrds_dir -B > > # open perms on rrdcached unix sock so http/apache can read rrd info > chmod -v 2777 /var/rrdtool/rrdcached/* regards, chris hunter chris.hun...@yale.edu > Message: 2 > Date: Fri, 7 Nov 2014 14:37:44 + > From: "Poirier, Keith" > Subject: [Ganglia-general] Problems getting rrdcached working with > Ganglia > To: "ganglia-general@lists.sourceforge.net" > > Message-ID: > > > Content-Type: text/plain; charset="us-ascii" > > I'm trying to follow the instructions at > https://github.com/ganglia/monitor-core/wiki/Integrating-Ganglia-with-rrdcached > - are they the most updated when it comes to integrating gmetad/rrdcached? > > > The first issue appears trying to use the following in > /etc/sysconfig/rrdcached on RH 6.5: > > OPTIONS="-p /tmp/rrdcached.pid -s apache -m 664 -l unix:/tmp/rrdcached.sock > -s nogroup -m 777 -P FLUSH,STATS,HELP -l unix:/tmp/rrdcached.limited.sock -b > /var/lib/ganglia/rrds -B" > RRDC_USER=nobody > > Nogroup doesn't exist.
