New question #253467 on Graphite: https://answers.launchpad.net/graphite/+question/253467
Just installed 0.10.0, this is not a problem on our older 0.9.x instance. I have some metrics that intentionally don't write frequently, only when there's a problem. When requesting these metrics if the from time is after the modified time of the whisper file graphite returns "no data". I verified this by doing a touch of the whisper file which then returns the "None,None..." as I would expect to see. Example: graphite@graphite1:/data/graphite/storage/whisper/Test$ date Fri Aug 22 10:06:18 UTC 2014 graphite@graphite1:/data/graphite/storage/whisper/Test$ ls -l total 1232 -rw-r--r-- 1 graphite graphite 1261468 Aug 22 00:32 Duration.wsp Point being the file is greater than 9 hours old Request a range newer than the file: curl -si "http://graphite/render?from=-9hours&until=now&target=Test.Duration&format=raw"; No data returned Adjust the range to be older than the file modification time: curl -si "http://graphite/render?from=-10hours&until=now&target=Test.Duration&format=raw"; Test.Duration,1408691700,1408727700,300|None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,......etc. Then if I touch the whisper file graphite@graphite1:/data/graphite/storage/whisper/Test$ touch Duration.wsp Then make the same 9 hour request again: curl -si "http://graphite/render?from=-9hours&until=now&target=Test.Duration&format=raw"; Test.Duration,1408695600,1408728000,300|None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,None,No.....etc. Hope this is clear. -- You received this question notification because you are a member of graphite-dev, which is an answer contact for Graphite. _______________________________________________ Mailing list: https://launchpad.net/~graphite-dev Post to : graphite-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~graphite-dev More help : https://help.launchpad.net/ListHelp
