OpenTelemetry can be used to [report various monitoring data (including metrics, logs and traces)](https://opentelemetry.io/docs/what-is-opentelemetry/) and is a de-facto industry standard. This mod provides additional instrumentation for the [OpenTelemetry JavaAgent](https://opentelemetry.io/docs/zero-code/java/agent/) so that various game metrics can be reported. The overall functionality is similar to [``fabric-exporter``](https://github.com/ruscalworld/fabric-exporter). ## Setup 1. Make sure you have an endpoint where OpenTelemetry data can be ingested.
This could be a [OpenTelemetry Collector](https://opentelemetry.io/docs/collector/) hosted by you or by someone else (e.g. in the [Grafana Cloud](https://grafana.com/docs/grafana-cloud/monitor-applications/application-observability/collector/)). 2. [Setup the OpenTelemetry Java Agent](https://opentelemetry.io/docs/zero-code/java/agent/getting-started/) so that it sends data to your ingestion service. 3. Add the [OpenTelemetry Agent Helper Extension for Fabric](https://github.com/litetex-oss/otel-fabric-helper-extension). * This is required so that the OpenTelemetry Agent is correctly detecting and utilizing the mod. 4. Simply add and (optionally) configure this mod. It should work out of the box. 5. Import the provided dashboard into Grafana * From [Grafana Dashboards](https://grafana.com/grafana/dashboards/23234) * From the [local demo in the repo](https://github.com/litetex-oss/mcm-otel-instrumentation-extension/tree/dev/_monitoring_dev_infra/docker-compose.yml)

If you wish to customize it, open ``config/oie.json`` and tune the corresponding values.
