Azure Integration - Application Gateway

Mackerel supports obtaining and monitoring Application Gateway metrics in Azure Integration. When integrating with Azure Integration, billable targets are determined using the conversion 1 Resource = 1 Micro Host.

Please refer to the following page for Azure Integration configuration methods and a list of supported Azure services.

The "#" in 'Metric name in Mackerel' holds one of the following.

  • BackendServer
    Indicates the IP address and port number for the backend server.
    IP addresses and port numbers are displayed separated by hyphens.
    For example, 127.0.0.1:8080 would be displayed as 127-0-0-1-8080.

      • Backend Connect Time
      • Backend First Byte Response Time
      • Backend Last Byte Response Time
      • Backend Response Status
  • BackendSettingsPool
    Indicates the backend pool and HTTP setting for the backend target.
    The backend pool and HTTP setting are displayed separated by a hyphen.
    For example, if the backend pool is backendpool and the HTTP setting is httpsetting, then it will be displayed as backendpool-httpsetting.
