This type of discussion is quite welcome on the list - most people have a threaded view of their emails these days, so it is not a hassle Can you clarify, your focus will be exclusively on metrics within gmond itself or you may also make metrics about the gmetad or rrdcached daemons' activity? In the biggest Ganglia install I was ever working with, it was very useful to have a version metric - in other words, a string metric with the full gmond version. The code is here: https://github.com/ganglia/monitor-core/blob/master/gmond/modules/status/mod_gstatus.c#L55 It sounds trivial, but in a heterogeneous network where every cluster is managed by different people and they do not all update their agents on the same day, it is very useful to know which clusters have which versions. Other people will have different requirements. Another interesting metric would be to extend the network stats to give per-NIC metrics. For each NIC, it would be nice to have some of the following: - a string metric with the MAC address - a numeric metric with the NIC speed (in bits per second) - the usual byte count and packet count metrics The source code of the multi-CPU and IO stats modules could provide some clues about how to make a multi-NIC module. ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
