Frequently asked questions

How do I start collecting metrics after installing the mod?
Install the OpenTelemetry Java Agent on your server, then add this mod and the Fabric helper extension to your mods folder. Start your server—it will automatically begin sending telemetry data to your configured OpenTelemetry collector endpoint or cloud monitoring account.
What's the difference between TPS and MSPT and why do I need both?
TPS (ticks per second) shows how many game ticks your server completes each second, while MSPT (milliseconds per tick) measures how long each individual tick takes. Together they reveal whether lag is caused by the server struggling to process ticks or by something else slowing the overall tick rate.
Can I monitor individual player stats like experience and levels?
Yes, but you need to enable it first. Set `metrics.enable-player-details-samplers` to true in your configuration to start tracking per-player metrics like experience, levels, and world location.
How do I reduce CPU usage from metric collection?
Enable `metrics.freeze-when-server-paused` to stop sampling when the server is idle, and use `metrics.enabled-only` to collect only the specific metrics you actually need instead of everything.
