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.
Furthermore it especially made for Minecraft itself. So you can also check your TPS (Ticks per seconds), player ping, server timings and so on.
Notice: This plugin is in beta. So improvements and bug fixes have to be made. Please report bugs and make suggestions.

Comment installer LagMonitor
A server on Paper or Spigot
The plugin runs on the server core for Minecraft 1.16–1.19.3; players do not need to install anything.
File goes into the plugins folder
Download the file LagMonitor.jar (2.5 MB) and put it into the server’s plugins folder.
Restart the server
On startup the plugin creates its own settings folder in plugins.
Use the “To server” button
On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.
Minecraft 1.19.3 runs on Java 17: with a different Java version the game may close right after launch.
