I am using Prometheus data source in Grafana connection. In dashboard, I need to query Prometheus with parameter in the URL (state).
Look at the following query:
URL : http://demo.do.prometheus.io:9090/graph?g0.expr=alertmanager_alerts{}&g0.tab=1&g0.display_mode=lines&g0.show_exemplars=0&g0.range_input=1h&state=unprocessed
notice (&state=unprocessed) at the end.
In Query: alertmanager_alerts{}
renders 3 rows:
| alertmanager_alerts{env=“demo”, instance=“demo.do.prometheus.io:9093”, job=“alertmanager”, state=“active”} | 6 |
|---|---|
| alertmanager_alerts{env=“demo”, instance=“demo.do.prometheus.io:9093”, job=“alertmanager”, state=“suppressed”} | 0 |
| alertmanager_alerts{env=“demo”, instance=“demo.do.prometheus.io:9093”, job=“alertmanager”, state=“unprocessed”} |
I need to filter rows and get just one row for state=“unprocessed”. My query is:
alertmanager_alerts{state=~‘$state’} ($state is in URL as a parameter)
It return NO rows. Please help me getting row for the above query.
Not sure what would be the correct query.
Thanks in advance
