Thanks for the pointers. The debug log shows this for the missing metrics:


[2016-08-11 17:47:48 -0500] warning/GraphiteWriter: Ignoring invalid 
perfdata value: in=0.000000B/s;10240000.000000;10240000.000000;0.000000
[2016-08-11 17:47:48 -0500] warning/GraphiteWriter: Ignoring invalid 
perfdata value: out=965.000000B/s;20480000.000000;20480000.000000;0.000000
[2016-08-11 17:47:48 -0500] warning/GraphiteWriter: Ignoring invalid 
perfdata value: in=0.000000B/s;10240000.000000;10240000.000000;0.000000
[2016-08-11 17:47:48 -0500] warning/GraphiteWriter: Ignoring invalid 
perfdata value: out=195.000000B/s;20480000.000000;20480000.000000;0.000000

Why would these entries be invalid? Because the in/out metrics are 
appended with "B/s"?

Thanks,

Michael

But, the performance metrics aren't making it into graphite. We turned on debuglog (icinga2 feature enable debuglog) and can see the perf data being properly returned, but it just ain't making it into graphite. Poking around in graphite's web app, nothing. Not there. Grafana can't see it, so we can't graph it.

By default the metrics/minute are set to a pretty low default value (max_updates_per_second, max_creates_per_minute, see my tuning over at the vagrant boxes - https://github.com/Icinga/icinga-vagrant/commit/6a6c53552c74040479331566dd683e3782ec8966)
