## Grafana Dashboard Guidelines
When creating or updating Grafana dashboards:
### Sorting Requirements
**ALWAYS ensure ALL panels are sorted by value (descending):**
1. **Time Series Panels:**
- Add to `options.legend`: `"sortBy": "Last", "sortDesc": true`
2. **Bar Gauge Panels:**
- Use `sort_desc()` in PromQL queries
- Example: `sort_desc(topk(10, sum by (label) (metric)))`
3. **Pie/Donut Chart Panels:**
- Add to `options.legend`: `"sortBy": "Value", "sortDesc": true`
4. **Table Panels:**
- Add to `options`: `"sortBy": [{"displayName": "ColumnName", "desc": true}]`
### Example Panel Configuration
**Time Series:**
```json
{
"type": "timeseries",
"options": {
"legend": {
"displayMode": "table",
"placement": "right",
"sortBy": "Last",
"sortDesc": true,
"calcs": ["lastNotNull", "mean", "max"]
}
}
}
```
**Bar Gauge:**
```json
{
"type": "bargauge",
"targets": [{
"expr": "sort_desc(topk(15, sum by (cust) (metric)))"
}],
"options": {
"orientation": "horizontal",
"displayMode": "gradient"
}
}
```
**Table:**
```json
{
"type": "table",
"options": {
"sortBy": [{"displayName": "Count", "desc": true}]
}
}
```
