This tool generates the Prometheus metrics documentation at docs/admin/integrations/prometheus.md.

The documentation is generated from two metrics files:

1. metrics (static, manually maintained)
2. generated_metrics (auto-generated, do not edit)

These files are merged and used to produce the final documentation.

Contains metrics that are not directly defined in the coder source code:

• go_*: Go runtime metrics
• process_*: Process metrics from prometheus/client_golang
• promhttp_*: Prometheus HTTP handler metrics
• coder_aibridged_*: Metrics from external dependencies

Edit this file to add metrics that should appear in the documentation but are not scanned from the coder codebase, or to manually override metrics where the scanner generates incorrect metadata (e.g., missing runtime-determined labels like in agent_scripts_executed_total).

Contains metrics extracted from the coder source code by the AST scanner (scanner/scanner.go).

Do not edit this file directly. It is regenerated by running:

make scripts/metricsdocgen/generated_metrics

To regenerate the documentation after code changes:

make docs/admin/integrations/prometheus.md

This will:

• Run the scanner to update generated_metrics
• Merge metrics and generated_metrics metric files
• Update the documentation file
