Trend Analyses to Produce
1. Daily Activity Trend
Plot daily_sessions and daily_events for the requested period. Compute:
- Average sessions/day and events/day
- Week-over-week delta (%)
- Peak day and quietest day
2. Token Volume Trends
From analytics tokens (baselines are pre-summed into totals at the DB level):
- Total tokens:
total_input,total_output,total_cache_read,total_cache_write - Cache efficiency over time:
total_cache_read / (total_cache_read + total_input)— trending up = improving - Output intensity:
total_output / total_inputratio — high = Claude is verbose
3. Tool Usage Ranking
From tool_usage (top 20 tools by event count):
- Bar chart data (tool name → count)
- Tool diversity: unique tools used
- Subagent spawns: count of "Agent" tool uses (each = a subagent launched)
4. Model Distribution
From agent_types + per-session model field:
- Which models are used most frequently
- Subagent type distribution: main (null) vs task vs explore vs code-review
5. Session Health Distribution
From sessions_by_status:
- Completion rate:
completed / total × 100 - Error rate:
error / total × 100 - Abandoned rate:
abandoned / total × 100
6. Event Type Distribution
From event_types:
- PreToolUse/PostToolUse ratio (should be ~1:1; gap = tools failing)
- Compaction frequency relative to session count
- APIError count (quota hits, rate limits, overloaded)
