Prometheus query to count unique label values

[Shilpa Akhilesh]

Hi, 

 am  looking for a way to count the unique label values and show each count for each customer name. Here are my metrics. I need to get the count as apple=1, orange=1. 

    customer_alerts(alertname="a", customername="apple")

     customer_alerts(alertname="b", customername="orange")

     customer_alerts(alertname="a",, customername="apple")

    i tried the below query and it is showing the total count as 2, but i would like to show the count map to each customer name. How can I do that?

    Example: apple=1, orange=1

    (count(count by (alertname)(customer_alerts[24h])))

    Please note I am using grafana to create the dashboard.

     Thanks,

      Shilpa

You can directly use the count function for this:

count by(customer) (customer_alerts)
