What plugin do i need?

I am looking for any plugins that can tell me what plugins on my server are using as far a recourse usage. Since my server has about 30 plugins i would like to know witch ones are using so much power.
If possible any info about plugin strain on the server. I use all of the plugins and would like to know if i can find a more light weight plugin to replace the ones i have.

 

Go into your server files -> plugins. Under each plugin it tells you how much usage they use.

 

start removing plugins 1 at a time seeing how much of a difference each one will make

edit: yes also highly consider what is posted below this

 

There could be a number of reasons your server lag:
-too many worlds
-too many entities in the world
-too little ram
-gigantic redstone/glowstone buildings

 

my server is running 8core cpu and 16gb or ram and i use a plugin to clean up entries. I have 6 world including nether and end. i also looked in the plugins folder and there is no info about how much power the plugins are using.
