Question #178316 on Graphite changed: https://answers.launchpad.net/graphite/+question/178316
Abe Stanway posted a new comment: @bhardy: After investigating, it only stops sending to all destinations if USE_FLOW_CONTROL is on, as per chrismd. Otherwise, it sends to all other destinations normally, and simply drops incoming datapoint for the disconnected destination only. We experienced issues in production using large MAX_QUEUE_VALUES and dealing with disconnecting/reconnecting listeners. Specifically, when a listener goes down, the queue fills up as it should, and relay stays alive. However, when the listener reconnects, relay dies as it tries to flush the queue all at once, because it blocks the IOLoop. Our solution was to use a very small MAX_QUEUE_SIZE (5000). There is a patch on the way from @mleinart to fix this behavior. -- 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
