AUTO-RESOLVED: CPU sustained below 70% for 2 consecutive checks. Current value: 22.9%

Handoff notes generated: # Shift Handoff Notes: claw-gateway1 CPU Alert - **Incident Summary**: CPU spike on claw-gateway1 reached 91.9% at 00:05 UTC on 2026-06-02; alert triggered and auto-resolved after 15 minutes when CPU dropped to 22.9% and remained stable. - **What Happened**: Single gateway experienced elevated CPU load with upward trend; memory pressure was low (26.3%), ruling out swap/GC issues. Root cause not definitively identified before auto-resolution. - **Actions Taken**: Auto-resolver confirmed CPU sustained below 70% threshold for 2 consecutive checks and closed the incident. No manual intervention was required. - **Current State**: RESOLVED. claw-gateway1 CPU now at 22.9% and stable. Gateway is operating normally. - **Watch For**: Monitor claw-gateway1 CPU over the next shift for recurrence. If spike repeats, SSH in and run `top -b -n 1 | head -20` to identify the runaway process. Check recent deployments or traffic anomalies as potential triggers. Restart process or gateway if CPU stays >80% sustained.

Handoff notes generated: # Shift Handoff Notes: claw-gateway1 CPU Alert - **What happened**: CPU spike on claw-gateway1 reached 91.9% (threshold: 90%) at 00:05 UTC on 2026-06-02; alert auto-resolved after dropping to 22.9% and sustaining below 70% for two consecutive checks. - **Root cause**: Likely a transient runaway process or load spike; memory was not under pressure (26.3%), so garbage collection/swap issues ruled out. - **What was done**: Alert was automatically investigated and resolved; no manual intervention required. CPU returned to normal within ~15 minutes. - **Current state**: RESOLVED — claw-gateway1 operating normally at 22.9% CPU; no ongoing issues detected. - **Next steps/watch for**: Monitor claw-gateway1 CPU trends over next shift. If spike recurs or sustains >80% for 15+ minutes, SSH in and run `top` to identify persistent high-CPU process; check recent deployments or traffic anomalies as potential triggers.

Handoff notes generated: # Shift Handoff Notes: claw-gateway1 CPU Alert - **What happened**: CPU spike on claw-gateway1 reached 91.9% (threshold: 90%) at 00:05 UTC on 2026-06-02; triggered P2 medium severity alert due to service degradation risk. - **Resolution**: Incident auto-resolved at 00:20 UTC after CPU dropped to 22.9% and remained stable below 70% for 2 consecutive checks. Root cause (runaway process or load spike) self-corrected; no manual intervention required. - **Current state**: RESOLVED. claw-gateway1 CPU now normal (~23%); memory pressure low (26.3%). No ongoing issues detected. - **Watch for**: Monitor claw-gateway1 CPU trends over next shift. If spike recurs, investigate via `top -b -n 1` to identify top CPU consumer. Check for recent deployments or traffic anomalies if pattern repeats. - **No action needed** at handoff unless spike returns; runbook available if escalation required.

Handoff notes generated: # Shift Handoff Notes: claw-gateway1 CPU Alert - **What happened**: CPU spike on claw-gateway1 reached 91.9% (threshold: 90%) on 2026-06-02 at 00:05 UTC; P2 medium severity alert triggered due to upward trend and service degradation risk. - **What was done**: Alert auto-resolved at 00:20 UTC after CPU dropped to 22.9% and remained below 70% for 2 consecutive checks. Root cause was likely a transient runaway process or load spike; memory was not under pressure (26.3%). - **Current state**: RESOLVED. claw-gateway1 is operating normally with CPU at 22.9%. - **Next shift should monitor for**: Recurrence of CPU spikes on this gateway. If spike returns, SSH in and run `top -b -n 1 | head -20` to identify the top CPU consumer process. Check for recent deployments or traffic anomalies. - **No further action required** unless CPU climbs above 80% again within the next 24 hours.

Handoff notes generated: # Shift Handoff Notes: claw-gateway1 CPU Alert - **Incident**: CPU spike on claw-gateway1 reached 91.9% (threshold: 90%) on 2026-06-02 at 00:05 UTC; triggered P2 medium alert due to service degradation risk. - **Resolution**: Alert auto-resolved after 15 minutes when CPU dropped to 22.9% and remained below 70% threshold for 2 consecutive checks (by 00:20 UTC). Root cause not explicitly identified—likely a transient load spike or runaway process that self-cleared. - **Current State**: Host is stable with CPU at 22.9%. No manual intervention was required. - **Next Steps**: Monitor claw-gateway1 CPU trends over the next 24 hours for recurrence. If spike returns, SSH in and run `top -b -n 1 | head -20` to identify the top CPU consumer (runaway process vs. distributed load). Check recent deployments or traffic anomalies if pattern repeats. - **Runbook Reference**: Available; memory was not under pressure (26.3%) at time of incident, ruling out GC/swap issues.
