- The red line on the chart represents the set threshold. Click on the right side and drag it up and down.
- Evaluate every `1m` for `5m`, Is the result calculated every minute, and the threshold is exceeded for five consecutive minutes.
- After setting for, if the state exceeds the threshold value and changes from Ok to Pending, the alarm will not be triggered. After continuously exceeding the threshold value for a period of time, the alarm will be sent. If the state changes from Pending to Alerting, the alarm will only be notified once.
- WHEN `avg ()` OF `query (B, 5m, now)` IS ABOVE `89`, That means line B has an average of more than 89 alarms in the last five minutes.
