The components of Ganglia The components of Ganglia are as follows:

1. The data collector (G)

• The daemon is a single file and called gmond (Ganglia MONitor Daemon!)
• Its configuration file /etc/gmond.conf
• This goes on each node

2. The data consolidator (G)

• The daemon is a single file and called gmetad (Ganglia METAdata Daemon!)
• Its configuration file /etc/gmetad.conf
• You need one of these for each cluster. On massive clusters you can have more than one and a hierarchy.

This daemon collects the gmond data set via the network and saves it in a rrdtool database.
