Hello everyone,
We have some problems with our alert rules. We have no clue where it comes from.
We are checking or web services with the blackbox exporter. This does not works properly.
The down mail working fine. But the service resolve mail does have the grafana state: MissingSeries.
All this services are scraping every minute. The rule evaluation interval is 2m30s.
What we have tested:
- Removing NaN values from the series.
- Using aggregation prometheus function.
- Increase the evaluation interval to have at least two metric data
This is our query setting:
and our no-data and error handling setting:
We are glad for any help to fix our issue.
