Actions¶

ARM Resource Actions (see Generic Actions)

Example Policies¶

This policy will filter load balancers with an ipv6 frontend public IP

policies:
  - name: loadbalancer-with-ipv6-frontend
    resource: azure.loadbalancer
    filters:
       - type: frontend-public-ip
         key: properties.publicIPAddressVersion
         op: in
         value_type: normalize
         value: "ipv6"

This policy will find all load balancers with 1000 or less transmitted packets over the last 72 hours

policies:
  - name: notify-inactive-loadbalancer
    resource: azure.loadbalancer
    filters:
      - type: metric
        metric: PacketCount
        op: le
        aggregation: total
        threshold: 1000
        timeframe: 72
