name: observability-analyzer description: Query and analyze Claude Code observability data (metrics, logs, traces). Use when analyzing performance, costs, errors, tool usage, sessions, conversations, or subagents.

Observability Analyzer

Query Claude Code telemetry and generate insights from metrics, logs, and traces. Works with both default OTEL telemetry and enhanced hook-based telemetry.

Data Sources

Source	Job Name	Contains
Default OTEL	claude_code	API metrics, token usage, costs
Enhanced Hooks	claude_code_enhanced	Sessions, conversations, tools, subagents

Operations

query-metrics <promql>

Execute PromQL query against Prometheus.

query-metrics 'sum(claude_code_token_usage)[7d]'

query-logs <logql>

Execute LogQL query against Loki.

query-logs '{job="claude_code_enhanced", event_type="tool_call"} | json' --since 24h

analyze-errors

Detect and group error patterns from enhanced telemetry.

{job="claude_code_enhanced", event_type="tool_result", status="error"} | json

Output: Error types, frequencies, affected tools, recommendations.

analyze-performance

Identify slow operations and response sizes.

{job="claude_code_enhanced", event_type="tool_result"} | json | response_length > 50000

Output: Large responses, estimated token costs, slow patterns.

analyze-costs

Calculate token usage from content size estimates.

sum by (repo) (sum_over_time({job="claude_code_enhanced", event_type="context_utilization"} | json | unwrap estimated_session_tokens [24h]))

Output: Token estimates by repo, session costs, projections.

analyze-tools

Tool usage statistics and sequences.

sum by (tool) (count_over_time({job="claude_code_enhanced", event_type="tool_call"} | json [24h]))

Output: Call frequency, success rates, tool sequences, common patterns.

analyze-sessions

Session lifecycle and duration analytics.

{job="claude_code_enhanced", event_type="session_end"} | json

Output: Session durations, turn counts, tools per session, termination reasons.

analyze-conversations

Conversation and prompt analytics.

sum by (pattern) (count_over_time({job="claude_code_enhanced", event_type="user_prompt"} | json [24h]))

Output: Prompt patterns (question/debugging/creation/ultrathink), turn distribution.

analyze-subagents

Subagent/Task tool usage.

{job="claude_code_enhanced", event_type="tool_call", tool="Task"} | json

Output: Subagent types used, completion rates, parallel execution patterns.

analyze-skills

Skill invocation analytics.

sum by (skill_name) (count_over_time({job="claude_code_enhanced", event_type="skill_usage"} | json [24h]))

Output: Most used skills, skill usage by repo, trends.

analyze-context

Context window utilization.

{job="claude_code_enhanced", event_type="context_utilization"} | json | context_percentage > 50

Output: High utilization sessions, compaction events, token efficiency.

analyze-repos

Repository/project activity.

sum by (repo, tool) (count_over_time({job="claude_code_enhanced", event_type="tool_call"} | json [24h]))

Output: Activity per repo, tool usage by project, branch patterns.

generate-report

Comprehensive analysis report (all dimensions). Output: Markdown report with errors, performance, costs, sessions, conversations, tools.
