OpenTelemetry metrics

You can configure monitoring and alerting using OpenTelemetry so that you're aware of potential issues before they negatively impact application performance or availability.

OpenTelemetry metrics are the foundation for monitoring GitHub Enterprise Server, available from version 3.18 onward. This monitoring stack provides enhanced observability and management capabilities compared to the legacy collectd system.

New installations of version 3.19 and later use OpenTelemetry metrics by default. On version 3.18, and on instances upgraded from earlier releases, collectd metrics are still gathered by default and remain supported in this release. Collectd is retired in version 3.23, and upgrading to 3.23 disables it. Migration to OpenTelemetry is recommended before upgrading instances that still use collectd. See Migrating from collectd to OpenTelemetry.

Note

OpenTelemetry metrics are in public preview and subject to change. We would love to hear your feedback on the preview. You can share it with your customer success team, or leave a comment in the community discussion post.
