Azure Monitor Custom Metrics Output for Telegraf

This plugin will send custom metrics to Azure Monitor.

All metrics are written as summarized values: min, max, sum, count. The Telegraf field name is appended to the metric name. All Telegraf tags are set as the metric dimensions.

Azure Authentication

This plugin can use one of several different types of credentials to authenticate with the Azure Monitor Custom Metrics ingestion API endpoint. In the following order the plugin will attempt to authenticate.

1. Managed Service Identity (MSI) token
   • This is the prefered authentication method.
   • Note: MSI is only available to ARM-based resources.
2. AAD Application Tokens (Service Principals)
   • Primarily useful if Telegraf is writing metrics for other resources. More information.
   • A Service Principal or User Principal needs to be assigned the Monitoring Contributor roles.
3. AAD User Tokens (User Principals)
   • Allows Telegraf to authenticate like a user. It is best to use this method for development.

# Configuration for sending aggregate metrics to Azure Monitor
[[outputs.azuremonitor]]
## The resource ID against which metric will be logged.  If not
## specified, the plugin will attempt to retrieve the resource ID
## of the VM via the instance metadata service (optional if running 
## on an Azure VM with MSI)
#resourceId = "/subscriptions/<subscription-id>/resourceGroups/<resource-group>/providers/Microsoft.Compute/virtualMachines/<vm-name>"
## Azure region to publish metrics against.  Defaults to eastus.
## Leave blank to automatically query the region via MSI.
#region = "useast"

## Write HTTP timeout, formatted as a string.  If not provided, will default
## to 5s. 0s means no timeout (not recommended).
# timeout = "5s"

## Whether or not to use managed service identity.
#useManagedServiceIdentity = true
