New question #216675 on Graphite: https://answers.launchpad.net/graphite/+question/216675
We've got the following setup on one server: * 1x carbon-relay * 3x carbon-caches behind the relay with consistent-hashing set So when we start up the relay & 3 caches, memory usage isn't too bad and all the caches use approximately the same amount of memory and the cache size is roughly the same as well. But after a period of time, one or two (but not all) of the carbon-caches blow out in memory usage and the system starts tanking. http://imgur.com/ZgGtT http://imgur.com/Y8qbP The weird part is that watching IO for each carbon-cache, it seems like at the moment, one of the caches is starving the other two for IO. Is there any way of tuning things so that one carbon-cache doesn't starve the others for IO? Currently I've got: MAX_UPDATES_PER_SECOND = 500 MAX_CREATES_PER_MINUTE = 400 Would tuning those values down help? How can I be sure that the IOs can be shared evenly? Is that at all possible? -- 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
