    Hello,

    Is there any way to see the RAM usage of an individual plugin?
    Having a memory leak on my 32GB server and can't tell which plugin it is caused by.

    Thanks!

    Essentials has this function , But easiest way is to tell us what plugins you have XD

    Here it is, don't think this will help though.

    What's the command for Essentials to do it?
    I only know of the /mem command which gives you total RAM usage, not individual plugin RAM usage.

    I think that NoLagg has this feature.

    NoLagg only outputs total RAM usage, not for individual plugins D:

    I haven't seen any plugin/feature which gives you opportunity to see how much does only the one plugin uses ram. But if you wanna to see how much each plugin uses, take all plugins out and then test one by one every plugin.
    Like: Put first DisguiseCraft plugin in plugins folder, then restart the server and check how much ram does you have used in the server, then you will see how much the plugin uses ram, after it take DisguiseCraft plugin out of the plugins folder and put there another one and repeat it until you won't find the plugin which causes the lagg or something.

    NoLagg Examine can output a file that shows individual plugin RAM usage.

    Oh okay, didn't know that.
    I'll try and find it =)

    Thanks!

    I tried NoLaggExamine but it seems like it only outputs time spent per plugin and not the RAM used.
    Is this true or am I skipping something here?

    Problem is the memory leak isn't always there, it only occurs every so often. D:
    Sometimes it will run fine for days, other times it eats up all the RAM crashing the server.

    Use a profiler.

    Haven't done anything with the profiling yet but I think YourKit would be appropiate for it.

    Okay thanks. Any specific steps I need to follow to check my servers ram per plugin?

    [INFO] Plugins (52): HardcoreDeathBan, GroupManager, ColourMotd, VoidtoSpawn, BukkitCompat, FastSoup, FusionJoin, Buycraft, Vault, AntiRelog, RuleBook, Shopkeepers, DisguiseCraft, CraftBay, Permissions, AntiAdvertising, FancyText, godPowers, DrugMeUp, PluginSpy, Tracking-Plugin, Votifier, GAListener, Citizens, LagMeter, HideStream, BananaBackup, WorldEdit, NoCheatPlus, TagAPI, SimpleExtras, WorldGuard, boosCooldowns, mChatSuite, OPLock, LimitedCreative, BKCommonLib, ZavAutoMessager, Auto arm, MoneyDrop, Essentials, MobDisguisePVPControl, SilkSpawners, MagicSpells, My Worlds, EssentialsChat, MobArena, EssentialsProtect, EssentialsSpawn, NameTags, EssentialsAntiBuild, Factions

    My ram drains from 85% free, to 84%, to 83%, and so on every 1-2 seconds it goes down 1% of free ram. Then once it reaches like 43% free it boosts back up to like 80% free, then so on. Also my server has 100 online, with 500 entities. 16 gigs ram, xeon E3 CPU

    Well using the profiler you can check which classes use the most memory and using that you can tell which plugin is causing the memory leak. Look up some tutorials if you don't know how =)

    Sorry for the late reply

    A profiler is an application which uses the JVM to output things such as RAM usage or CPU usage. A good one is VisualVM, I personally use YourKit.
