Hi, I have a rather large and complicated ganglia deployment, which can almost certainly be simplified, I just don't know how.
Anyway, the issue that I am trying to resolve is a gmetad which dozens of gmond datasources is writing summary data for some of these datasources, but not writing the host metrics, they all show NaN in the rrds. Another gmetad with the same datasource IS able to write the host metrics, so I dont know why this one wont. The datasource configuration is identical (literally copy/paste from one config file to generate a new one). Running the affected gmetad with -d 3, I cannot see any "Updating host" lines for the hosts affected, but I can see it writing the summary data. The particular part of the deployment we are having issue with is this: We have 2 ganglia collectors, running dozens of gmond instances to collect data from different logical groups of servers (web server group, app server group, cache server group etc). These are then aggregated into their logical systems (external website, internal website, database servers etc) by a number of gmetad instances, and those gmetad instances are then aggregated by another gmetad (so we have grid of grids, sometimes nested 3 deep). We have one other gmetad instance running on a nagios machine with ALL gmond instances as sources, to aggregate everything, so we can use the nagios integration scripts. Software versions: clients are running a mix of 3.1.2 and 3.1.7 collector machines are running 3.1.7 nagios machine is running 3.4.0 (built from github to include the grid of grids fix) Finally, if someone has experience with deployments like this, and can offer some advice on how to simplify down from dozens of gmond and gmetad configs, that would be much appreciated. This has grown organically over the years, and is simply getting out of hand.
