Hi. I am a little bit confused why and when graphite graphs are showing up in icingaweb2 and when not.
E.g. for my self-defined “maildelivery” check I do get a nice graph for the performance data:
but for a different check called “uptime” I don’t:
Both deliver performance data and I don’t see a difference in the check definitions.
Could someone enlighten me please? 
Thanks!
Can you check Graphite directly or look in the whisper folder to see if you can find wsp files for those metrics? Not sure if its a problem on the Icinga, Graphite or Carbon side.
Also, are you using multiple carbon-cache daemons? A config error can cause some metrics to get lost but others to appear just fine.
Additionally:
If there are no corresponding whisper files:
Although not very likely, do you accidentally use matching backlist-entries in the
/etc/carbon/carbon.blacklist
and have whitelisting (which also activates blacklisting) enabled in the
/etc/carbon/carbon.conf
?
Greetings.
Thank you, good points!
White/blacklisting ist not enabled. Only one carbon-cache daemon.
But there are actually no whisper files. This encouraged me to restart the carbon-cache daemon (was running for 7 days) and … … suspense … … graphs are created again!
So it had nothing to do with icinga.
Sorry for the noise and thanks a lot for your quick help!

I had the same issue - I have created a new service in Icinga, but no Graph was displayed for it.
When I added “&graph_debug=1” to Icinga url, I have seen log message that 0 metrics was fetched.
I have opened the Graphite UI at http://localhost:4322/ and found graphs for other services, but the new one was not here too.
Then have I found hint here: retention in /etc/carbon/storage-schemas.conf should be aligned with the check_interval of the service, otherwise Graphite does not aggregate metrics correctly sometime - I have changed the check_interval to “1m” as the retention period in carbon and it works now
