28-28: Add description for the dashboard IDThe dashboard ID
4should be documented with a comment explaining its significance and whether it needs to be unique across different Grafana installations.
6080-6080: Consider adjusting the refresh interval based on loadThe refresh interval of "10s" might be too aggressive for high-load environments. Consider making this configurable or increasing it to reduce Prometheus query load.
- "refresh": "10s", + "refresh": "${dashboard_refresh_interval:default=30s}",
6166-6174: Optimize variable query for better performanceThe pod variable query could be optimized by adding a time range filter to improve query performance.
- "definition": "label_values(greptime_app_version{app=~\"$roles\"},pod)", + "definition": "label_values(greptime_app_version{app=~\"$roles\"}[5m],pod)",
2992-2992: Inconsistent drawStyle configuration across panelsSome panels use
"drawStyle": "points"while others use"drawStyle": "line". This inconsistency makes it harder to compare metrics visually. Consider standardizing the style based on the metric type:
- Use "line" for continuous metrics (e.g., memory, CPU)
- Use "points" for discrete events (e.g., p99 latencies)
Also applies to: 3088-3088, 3209-3209, 3426-3426, 3847-3847, 3943-3943

6080-6303: Add dashboard version and revision historyThe dashboard lacks version tracking and revision history. Consider adding:
- A version tag in the dashboard title
- A description field documenting major changes
- Links to related dashboards
"title": "GreptimeDB Cluster Metrics", + "description": "Version: 1.0\nLast updated: 2024-11\n\nChangelog:\n- Initial release\n\nRelated dashboards:\n- GreptimeDB Node Metrics\n- GreptimeDB Query Analytics", "uid": "ce3q6xwn3xa0wa",

1-6303: Consider implementing dashboard best practicesSeveral Grafana dashboard best practices could be implemented:
- Add documentation panels explaining metrics
- Group related variables
- Add dashboard-level alerts
- Implement consistent panel sizing
- Add drill-down links to detailed views
