Claude Code OpenTelemetry Monitoring

Monitor your Claude Code usage with a complete observability stack: OpenTelemetry Collector, Prometheus, Loki, and Grafana. Track costs, token usage, cache efficiency, active time, and code changes in real-time with pre-built dashboards. Watch and check back for updates to this repo for step by step instructions for setting this up. Still fine-tuning the charts and panels.

An accompanying Claude Code usage metrics MCP server allows Claude Code access to it's own usage metrics (see below example along with example screenshots).

Based on Official Claude Code Documentation: Claude Code supports OpenTelemtry as described in Anthropic's official monitoring documentation.
