There is a Ganglia aggregator running:
- gmond
- gmetad
And three Ganglia agents working in unicast mode, to publish data to the aggregator.
From one of the Ganglia agents, I manually push new metrics using gmetric
CLI utility, and I see it plotted on the Web dashboard connected to the aggregator.
If new metrics can be published in this way, then what is the use of "gmond collection group" and those metrics definitions in gmond.conf
?
