Here is an overview of how we label metrics.
There are a couple of scenarios where labels are being added:
- Built-in labels
- Metric dimension labels
- Scaler-specific labels
- Bring-your-own labels
In case of duplicate label names the above priority will be used.
Built-in labels
Every metric that is being reported in the scraping endpoint comes with the following built-in labels:
resource_uri- Full resource URI of the instance. (iesubscriptions/xxx/resourceGroups/yyy/providers/Microsoft.ServiceBus/namespaces/promitor)subscription_id- Id of the subscription.resource_group- Name of the resource group.instance_name- Name of the instance, if applicable.
Metric dimension labels
Metrics support specifying a dimension which will be scraped in Azure Monitor.
Every metric value will be reported under the configured metric name, but a label for the dimension and it’s respective value will be added.
Scraper-specific labels
Every scraper can provide additional labels to provide more information.
Currently we support this for:
- Azure API Management
- Azure Function App
- Azure Service Bus
- Azure SQL Database
- Azure Storage Queue
- Azure Web App
For more information, we recommend reading the scraper-specific documentation.
Custom Labels
As of v1.0, you can define your own labels by configuring them for a specific metric.
For more information, see “Metrics”.
