TPS Detective

by Catomon

TPS Detective shows server tick statistics in a GUI, so a freeze can be traced to the cause that stops the server responding.

What it does

Pressing O opens a screen where tick times are shown in real time as an overlay. Entity tick times, structure generation times and the last task the server ran are listed, which helps find the source of a drop to 0 TPS. Tick lag caused by a villager is one example of what the screen can reveal. The mod works in singleplayer only, not on dedicated servers. It is published for Forge and NeoForge across 7 release versions, 1.20.1 – 1.21.1, and it runs on client and server. The code is not open source, and all rights are reserved.

Key features

  1. Tick statistics screen

  2. Freeze detection

    The GUI shows when the server stops responding and the world sits at 0 TPS.

  3. Entity and structure timings

    Entity tick times, structure generation times and the last server task are listed to locate the cause of lag.

What the author says

This thing shows entity tick times and structure max gen times and also the last task server was busy doing if the server stops responding (frozen world, 0 TPS). Press 'O' to see the snapshot screen where you can also turn on realtime overlay.
