Grafana Dashboards

I have alert group state firing within 24hr is 2 alert group

I want to count alert group within 24hr.I use promql in dashboard

grafanacloud_oncall_instance_alert_groups_total{slug="test_stack", integration="Grafana Alerting", state="firing"}**

but data show is 0 what i’m wrong

2

It’s counter, so I guess (fix any syntax issues and 24h grouping):

sum(
  difference(
    grafanacloud_oncall_instance_alert_groups_total{
      slug=“test_stack”,
      integration=“Grafana Alerting”,
      state=“firing”
     }[$__range] 
  )
)
