This page covers advanced diagnostic procedures for investigating PRX issues that are pas resolved par le basic troubleshooting steps.

Diagnostic Commands

prx doctor

The comprehensive health check:

prx doctor

Output includes:

• Configuration validation results
• Provider connectivity tests
• System dependency checks
• Resource usage summary

prx debug

Enable debug-level logging for detailed operation traces:

PRX_LOG=debug prx daemon

Or set in config:

[observability]
log_level = "debug"

prx info

Display system information:

prx info

Shows:

• PRX version and build info
• OS and architecture
• Configured fournisseurs and their status

Performance Profiling

Enable the metrics endpoint and use Prometheus/Grafana for performance analysis:

[observability.metrics]
enabled = true
bind = "127.0.0.1:9090"

Key metrics to monitor:

• prx_llm_request_duration_seconds -- LLM latency
• prx_sessions_active -- concurrent sessions
• prx_memory_usage_bytes -- memory consumption
