I'd like to work on this issue.
Here's my proposed metrics plan:
**Phase 1 — System (wire existing sysinfo data to Prometheus)**
- iggy_process_cpu_usage (Gauge) — process CPU %
- iggy_memory_usage_bytes (Gauge) — process RSS
- iggy_messages_size_bytes (Gauge) — total messages on disk
- iggy_consumer_groups (Gauge) — consumer group count
- iggy_uptime_seconds (Gauge) — server uptime
**Phase 2 — Throughput & Consumer Lag**
- iggy_messages_sent_total, iggy_messages_polled_total (Counter)
- iggy_bytes_sent_total, iggy_bytes_polled_total (Counter)
- iggy_consumer_lag (Gauge, labels: consumer/topic/partition) —
current_offset - stored_offset
**Phase 3 — Connections**
- iggy_connections_active{transport=tcp|quic|http|ws} (Gauge)
- iggy_connections_total{transport=tcp|quic|http|ws} (Counter)
**Phase 4 — Auth**
- iggy_login_attempts_total, iggy_login_failures_total (Counter)
**Phase 5 — Storage & Ops**
- iggy_segments_rotated_total, iggy_segments_expired_total,
iggy_messages_expired_total (Counter)
- iggy_stale_clients_evicted_total (Counter)
- iggy_messages_deduplicated_total (Counter)
Start with Phase 1-2 in the first PR then follow up with the rest
If there are any additional metrics you'd like to see or specific priorities
please let me know
