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.
