Maykesh's Server Observability Framework

by pz.labs

Maykesh's Server Observability Framework gives Fabric server operators a telemetry layer for tick timings, entity updates, chunk loading and network packets, and requires Fabric API.

FabricServer required, client optionalCreative Commons Attribution Non Commercial Share Alike 4.01.21

What it does

A modular set of collectors feeds a central telemetry bus, so tick timings, entity updates, chunk loading and network packets can be read from one place. Structured telemetry is exposed for developers building tools on top of the server runtime. The framework reports runtime data without changing gameplay.

The first public build, 1.0.0 for 1.21, is a beta file dated 2026-06-27 and covers only Minecraft 1.21. It is required on the server and optional for players. Fabric API must be installed alongside it. The mod is released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license and is not open source.

Key features

  1. Tick and entity timings

    Tick timings and entity update costs are measured while the server runs, to help with debugging and optimisation.

  2. Chunk loading and packets

    Chunk loading and network packet activity are instrumented so operators can see where server time is spent.

  3. Core collectors and telemetry bus

    Modular collectors publish their readings to a shared telemetry bus that other tools can subscribe to.

  4. Rate-limiting diagnostics

    Utilities for diagnosing and rate-limiting systems are included alongside the collectors.

Use cases

Server performance debugging

Operators can check which tick, entity or chunk work takes the most time when the server lags.

Developer tooling

Developers can read the structured telemetry output to build their own monitoring or exporters.

Who it’s for: Server owners who want detailed runtime measurements on Fabric 1.21 servers, and developers who build tools on top of the server telemetry stream.

Questions

Does Maykesh's Server Observability Framework need to be on the client?

No. Only the server has to run it, and players can join without installing it, since clients are free to skip it.

Which Minecraft version does the framework support?

The only listed game version is 1.21, and the latest Fabric file, 1.0.0 for 1.21, is a beta build.

Does the framework need Fabric API?

Yes. Fabric API is a required dependency and must be installed on the server alongside the framework.
