Question #216675 on Graphite changed: https://answers.launchpad.net/graphite/+question/216675
Description changed to: 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 (the one with the lowest memory usage) 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
