# `prometheus.exporter.azure`

The `prometheus.exporter.azure` component embeds [`azure-metrics-exporter`](https://github.com/webdevops/azure-metrics-exporter) to collect metrics from [Azure Monitor](https://azure.microsoft.com/en-us/products/monitor).

The exporter supports all metrics defined by Azure Monitor. You can find the complete list of available metrics in the [Azure Monitor documentation](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/metrics-supported). Metrics for this integration are exposed with the template `azure_{type}_{metric}_{aggregation}_{unit}` by default. As an example, the Egress metric for BlobService would be exported as `azure_microsoft_storage_storageaccounts_blobservices_egress_total_bytes`.

The exporter offers the following two options for gathering metrics.

1. (Default) Use an [Azure Resource Graph](https://azure.microsoft.com/en-us/get-started/azure-portal/resource-graph/#overview) query to identify resources for gathering metrics.
   
   1. This query makes one API call per resource identified.
   2. Subscriptions with a reasonable amount of resources can hit the [12000 requests per hour rate limit](https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/request-limits-and-throttling#subscription-and-tenant-limits) Azure enforces.
2. Set the regions to gather metrics from and get metrics for all resources across those regions.
   
   1. This option makes one API call per subscription, dramatically reducing the number of API calls.
   2. This approach doesn’t work with all resource types, and Azure doesn’t document which resource types do or don’t work.
   3. A resource type that’s not supported produces errors that look like `Resource type: microsoft.containerservice/managedclusters not enabled for Cross Resource metrics`.
   4. If you encounter one of these errors you must use the default Azure Resource Graph based option to gather metrics.

## Authentication

Alloy must be running in an environment with access to Azure. The exporter uses the Azure SDK for go and supports [authentication](https://learn.microsoft.com/en-us/azure/developer/go/azure-sdk-authentication?tabs=bash#2-authenticate-with-azure).

The account used by Alloy needs:

- When using an Azure Resource Graph query, [read access to the resources that will be queried by Resource Graph](https://learn.microsoft.com/en-us/azure/governance/resource-graph/overview#permissions-in-azure-resource-graph).

<!--THE END-->

- Permissions to call the [Microsoft.Insights Metrics API](https://learn.microsoft.com/en-us/rest/api/monitor/metrics/list) which should be the `Microsoft.Insights/Metrics/Read` permission.

The list of available `resource_type` values and their corresponding `metrics` can be found in [Azure Monitor essentials](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/metrics-supported).

The list of available `regions` to your subscription can be found by running the Azure CLI command `az account list-locations --query '[].name'`.

The `resource_graph_query_filter` can be embedded into a template query of the form `Resources | where type =~ "<resource_type>" | <resource_graph_query_filter> | project id, tags`.

Valid values for `metric_aggregations` are `minimum`, `maximum`, `average`, `total`, and `count`. If no aggregation is specified, the value is retrieved from the metric.

For example, the aggregation value of the metric `Availability` in [Microsoft.ClassicStorage/storageAccounts](https://learn.microsoft.com/en-us/azure/azure-monitor/reference/supported-metrics/microsoft-classicstorage-storageaccounts-metrics) is `average`.

Every metric has its own set of dimensions.

For example, the dimensions for the metric `Availability` in [Microsoft.ClassicStorage/storageAccounts](https://learn.microsoft.com/en-us/azure/azure-monitor/reference/supported-metrics/microsoft-classicstorage-storageaccounts-metrics) are `GeoType`, `ApiName`, and `Authentication`.

If a single dimension is requested, it will have the name `dimension`. If multiple dimensions are requested, they will have the name `dimension<dimension_name>`.

Tags in `included_resource_tags` will be added as labels with the name `tag_<tag_name>`.

Valid values for `azure_cloud_environment` are `azurecloud`, `azurechinacloud`, `azuregovernmentcloud` and `azurepprivatecloud`.

`validate_dimensions` is disabled by default to reduce the number of Azure exporter instances required when a `resource_type` has metrics with varying dimensions. When `validate_dimensions` is enabled you will need one exporter instance per metric + dimension combination which is more tedious to maintain.

`timespan` and `interval` are used to control how metrics are queried from Azure Monitor. The exporter queries metrics over the `timespan` and returns the most recent datapoint at the specified `interval`. If you are having issues with missing metrics, try increasing the `timespan` to a larger value, such as `PT10M` for 10 minutes, or `PT15M` for 15 minutes.

## Blocks

The `prometheus.exporter.azure` component doesn’t support any blocks. You can configure this component with arguments.

## Exported fields

The following fields are exported and can be referenced by other components.

Expand table

| Name      | Type                | Description                                               |
|-----------|---------------------|-----------------------------------------------------------|
| `targets` | `list(map(string))` | The targets that can be used to collect exporter metrics. |

For example, the `targets` can either be passed to a `discovery.relabel` component to rewrite the targets’ label sets or to a `prometheus.scrape` component that collects the exposed metrics.

The exported targets use the configured [in-memory traffic](../../../../get-started/component_controller/#in-memory-traffic) address specified by the [run command](../../../cli/run/).

## Component health

`prometheus.exporter.azure` is only reported as unhealthy if given an invalid configuration. In those cases, exported fields retain their last healthy values.

## Debug information

`prometheus.exporter.azure` doesn’t expose any component-specific debug information.

## Debug metrics

`prometheus.exporter.azure` doesn’t expose any component-specific debug metrics.

            username = "<USERNAME>"
            password = "<PASSWORD>"
        }
    }
}
```

Replace the following:

- *`<SUBSCRIPTIONS>`* : The Azure subscription IDs holding the resources you are interested in.
- *`<PROMETHEUS_REMOTE_WRITE_URL>`* : The URL of the Prometheus remote\_write-compatible server to send metrics to.
- *`<USERNAME>`* : The username to use for authentication to the `remote_write` API.
- *`<PASSWORD>`* : The password to use for authentication to the `remote_write` API.
