- Check if Exq process is running before attempting to collect metrics
- Change rescue to catch to handle process exits (:noproc)
- Prevents error logs in environments where Exq is not configured
Added telemetry metrics for monitoring:
Exq Metrics:
- Queue sizes for all queues (default, discovery, polling, monitoring, maintenance)
- Number of busy worker processes
- Total number of worker processes
Redis/Valkey Metrics:
- Connected clients
- Memory usage
- Total commands processed
Metrics are collected every 10 seconds via telemetry_poller and displayed
in LiveDashboard at /dashboard
