New question #246639 on Graphite: https://answers.launchpad.net/graphite/+question/246639
Greetings, I am facing strange behaviour of Graphite infrastructure - there are latest datapoints missing from graphs. My infrastructure contains: a) 1x dedicated graphite-web for unique access point for any dashboard tool b) 2x relay hosts running carbon-relay only c) 2x storage hosts running carbon-cache (and graphite-web) only The intention of this deployment design is as follows: - any node sends datapoints metrics to one from defined relay hosts, - this relay hosts know about all (currently 2) storage nodes and using consistent-hashing distributes datapoints among them, - storage node with 'MAX_UPDATES_PER_SECOND = 50' and 'MAX_CACHE_SIZE = inf' saves datapoints to whisper database The issue I am facing is that mostly in each graph there are missing latest datapoint from some metrics. My dashboarding tool (Grafana) is asking the graphite-web node (a) which is aware of all carbon-cache (storage) nodes defined in CLUSTER_SERVERS directive of local-setings.py. What could be the reason of missing data? I assume there should be at least datapoints from all metrics up to some time but not in spread for i.e. 5 minutes. Thank you for your ideas and help, regards .zp. -- 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 : [email protected] Unsubscribe : https://launchpad.net/~graphite-dev More help : https://help.launchpad.net/ListHelp
