Trace Bullet
by korti
Trace Bullet is a NeoForge server mod that exports performance and gameplay metrics over OpenTelemetry to an observability platform.
What it does
Trace Bullet runs alongside a Minecraft server and continuously collects metrics such as tick rate, player count, chunk count and entity count. It sends them over OTLP to a compatible observability backend, so server owners can watch trends, set alerts and spot problems before players notice them. It is a server-side only mod: players join without installing anything, and only the server runs it.
Setup begins by dropping the mod JAR into the mods folder and starting the server once to generate its configuration file. The endpoint URL and service name are then set in that file, and the observability stack is pointed at the same endpoint. OpenTelemetry is bundled with the mod, so no separate install is required. Trace Bullet is released under the MIT License, is open source, and is published for NeoForge on Minecraft 26.1.2 only, with the latest file, 0.1.2, marked as a beta build.
Key features
OTLP metric export
Server metrics are sent over OTLP, so any compatible observability backend can receive them without a custom adapter.
Tick, player, chunk and entity counts
The collected metrics cover tick performance, connected players, loaded chunks and live entities, updated continuously while the server runs.
Per-metric toggles
Each metric can be switched on or off individually, so only the figures a server owner needs are exported.
Custom resource attributes
Extra resource attributes can be attached to the exported data, which helps label several servers in one backend.
Grafana dashboard included
A ready-made Grafana dashboard ships with the release as a starting point for viewing the collected metrics.

Use cases
Monitoring a busy server
Owners of multiplayer servers can track tick performance and entity counts over time and see when load starts to climb.
Alerting on problems
Alerts can be set in the observability platform on the exported metrics, so a drop in performance triggers a warning before players complain.
Who it’s for: Server owners and hosting administrators who already run, or plan to run, an OpenTelemetry-compatible observability platform such as a metrics stack with Grafana. Players who only join a server do not need this mod.
