Handoff notes generated: # Shift Handoff Notes: claw-gateway1 CPU Alert - **Incident Summary:** CPU spike to 93.4% on claw-gateway1 triggered MEDIUM alert at 16:05 UTC on 2026-05-18. Likely causes identified: runaway process, sudden traffic spike, or memory pressure. - **Resolution:** Alert auto-resolved at 16:20 UTC after CPU dropped to 44.0% and remained below 70% clear threshold for 2 consecutive checks (~15 min sustained). - **Current State:** RESOLVED. claw-gateway1 CPU stable at 44.0%. No service outage reported. Alert cleared without manual intervention. - **Root Cause Unknown:** Spike was transient; underlying cause (process, traffic, or memory) not identified. Runbook unavailable at time of incident. - **Watch For:** Monitor claw-gateway1 CPU for recurring spikes over next shift. If spike recurs, SSH in and run `top` to identify top CPU consumer, then cross-reference recent deployments/config changes. Check memory levels (was at 45.4%) for creep toward swap/GC cycles.

CPU sustained at ~44% well below the 70% clear threshold; no ongoing service degradation observed. - **What next shift should monitor:** Watch for CPU creep on claw-gateway1 over the next 24 hours. If spike recurs, SSH in and run `top` to identify the top CPU consumer; also check recent deployments or config changes. If a single process consistently consumes >50% CPU, consider restart or escalation. - **No action required now:** Incident fully auto-resolved; runbook unavailable but infra health and past incident context were sufficient for monitoring.

Handoff notes generated: # Shift Handoff Notes: claw-gateway1 CPU Alert - **Incident:** CPU spike to 93.4% on claw-gateway1 triggered MEDIUM alert at 16:05 UTC on 2026-05-18; auto-resolved at 16:20 after CPU dropped to 44%. - **Root Cause:** Likely runaway process or sudden traffic spike; memory pressure possible. No root cause definitively identified before auto-resolution. - **Current State:** RESOLVED. CPU stable at 44.0% for past 2+ hours; no service outage reported. - **Actions Taken:** Alert auto-resolved via threshold clearing (CPU <70% for 2 consecutive checks). No manual intervention required. - **Watch For:** Monitor claw-gateway1 CPU trending over next shift. If spikes recur, SSH in and run `top` to identify runaway processes or check deployment logs for recent config changes in the 30 min prior to spike.
