No data points in grafana:
I found out that my grafana had no data points in the 7 days view. My new icinga2 check worked correctly and produced the right data.
nano /etc/icinga2/zones.d/master/services/disks.conf import "10minute-service"
In my apply service declaration i defined the check as a 10 minute service.
In my carbon config i have defined the retentions:
nano /etc/carbon/storage-schemas.conf [default_1min_for_1day] pattern = .* #retentions = 60s:1d retentions = 1m:2d,5m:10d,30m:90d,360m:4y
As you can see i don’t have a setting for 10 minutes. If you add this timespan your graphs should work again.
[default_1min_for_1day] pattern = .* #retentions = 60s:1d retentions = 1m:2d,5m:10d,10m:20d,30m:90d,360m:4y
You need to delete the whisper file and restart the services/reboot to get it working.
rm /var/lib/graphite/whisper/icinga2/homeserver_mattionline_lan/services/shm/disk/perfdata/_dev_shm/value.wsp reboot
