How to set "Alertmanager data source" in Alerting section for a Prometheus data source via helm chart

[phongvq]

Hello team,
In a Prometheus Data source UI in Grafana, we have a place to select Alertmanager data source (The alert manager that manages alerts for this data source).
I wonder how we can set it via helm chart or datasource provision file.

I've tried to specify alertmanagerUid for the datasource, but it didn't work.

    - name: gmp-dataplatform-296603-prod-01
      access: proxy
      editable: false
      jsonData:
        tlsSkipVerify: true
        manageAlerts: true
        alertmanagerUid: Alertmanager
      orgId: 1
      type: prometheus
      url: http://prometheus.monitoring.svc:9090
      version: 1

Thank you guys very much.

Ok I will answer my own question.
I need to specify the uid of Alert Manager, not the name of it.
should be something like: alertmanagerUid: KBFA4AR4k.

To get the UID, you can use one of the following ways:

• specify the UID when configure Alert
• click into the Alert Manager data source in Grafana UI and copy it from the URL
• get it from grafana config file

Btw, it's weird that in Grafana document, they don't mention alertmanagerUid fields in jsonData, but somehow it works.
