Observe Metrics

Aggregate counters, gauges, and histograms from the observability namespace and flag anomalies.

When to use

When you need a snapshot of system health -- task completion rates, error rates, active agent counts, memory usage, and token consumption. Useful for monitoring swarm performance and detecting degradation.

Steps

1. Retrieve metrics -- call mcp__claude-flow__agentdb_hierarchical-recall to fetch metric records from the observability namespace for the specified period (default: 1 hour)
2. Aggregate -- compute:
   • Counters: sum totals (tasks_completed, errors, token_usage)
   • Gauges: current values (active_agents, memory_usage_bytes)
   • Histograms: p50, p95, p99 (task_duration_ms, span_duration_ms)
3. Compute baselines -- search for historical patterns via mcp__claude-flow__agentdb_pattern-search to establish baseline values for each metric
4. Flag anomalies -- mark metrics deviating >2 standard deviations from baseline with direction (above/below) and severity
5. Store patterns -- call mcp__claude-flow__agentdb_pattern-store to record current metric snapshot for future baseline comparison
6. Report -- display: metric name, current value, baseline, deviation, trend (up/down/stable), anomaly flag; overall health score (green/yellow/red)
