for a complete overview we recommend reading the
[official documentation](https://docs.microsoft.com/en-us/azure/azure-monitor/platform/metrics-supported).

## How does Promitor handle deleted resources?

The approach depends if you are using declarative metrics or resource discovery but we highly recommend to
**enable Prometheus metric timestamps** in [our runtime configuration](/configuration/v2.x/runtime/scraper/#prometheus-scraping-endpoint)
to indicate how old the metric is.

### When using declarative metrics

Promitor will scrape all resources that are configured and report the metrics accordingly. If that resource is deleted,
we will **still serve the metrics as long as we can until it is no longer available and exceptions will be thrown**.

We **recommend to update the metrics declaration when a resource is deleted** to avoid polluting logs.

### When using resource discovery

Promitor will automatically discover all matching resources which means that **it will automatically scrape metrics for
new/removed resources**.

Removed resources will immediately stop being scraped by Promitor, but still be reported in Prometheus scrape endpoint.

## Is scraping multiple subscriptions supported?

No, we do not support scraping multiple subscriptions as of today as we consider that to be a security boundary.
