LagMonitor

Description

Gives you the possibility to monitor your server performance. This plugin is based on the powerful tools VisualVM and Java Mission Control, both provided by Oracle. This plugin gives you the possibility to use the features provided by these tools also in Minecraft itself. This might be useful for server owners/administrators who cannot use the tools.
