Bukkit Plugin Task manager / Activity Monitor

I was wondering, is there any way to know how much ram a specific plugin is using within Bukkit?

I'd love to have a way to objectively compare how much of an impact one plugin has on my server's performance vs. another.

Is there currently a way to do this? If not, it'd be sweet if there was a way to add this as a feature for bukkit, since it would make debugging a server's performance way easier.

 

thats an exelent idea. i dont know of any plugin that can do that. would be nice to see cpu usage of plugins as well if thats even possible.

 

Yup, a tool that will help analyzing server performance would be great idea.

One problem may be that plugin may start up threads, which are hard to analyze. But those threads starts in another processor cores (i guess most servers have at least 2 cores now), so impact on bukkit should not be big.

 

That'd be a great tool to have

 

Well, I found this old topic: http://forums.bukkit.org/threads/monitoring-plugin-memory-usage-slow-but-workable.14011/ Which seems to have a way to do it, using some java hackery. Does anyone have enough java know-how to figure out how to get it to work?

 

Well It's not only memory usage. Plugin may use only 10kb of your memory, but it would use 50% of the CPU.

 

The Bukkit team could add some plugin monitoring. They could track how much time each plugin eats per cycle.
