Automatic Service Detection

When container_and_service_enable is set to true, Glouton automatically detects all known services running on the machine — whether they run as host services or inside containers — and starts collecting their logs without any per-service configuration.

log.opentelemetry.auto_discovery.container_and_service_enable: true

This option is also enabled when using all_enable.

Each service has a built-in log format that parses log lines into structured fields (e.g., HTTP method, status code, client IP, severity level).

Supported Services
