Prompt Patterns
- Average response_time_ms by hour_of_day and weekday last 14 days heatmap.
- Count of errors by service_name and severity last 7 days heatmap.
Best Practices
- Ensure both axes have limited cardinality (
<24each). - Provide consistent metric scale.
Common Mistakes
- High cardinality axes causing unreadable tiles.
