May 20, 2021 - When deploying in-cluster, a common pattern to collect metrics is to use Prometheus or another monitoring tool to scrape the metrics endpoint exposed by your application. As an example, when running in Azure Kubernetes Services (AKS), you can configure Azure Monitor to scrape prometheus metrics exposed by dotnet-monitor.

October 11, 2022 - In addition to the collection of System.Runtime and Microsoft.AspNetCore.Hosting metrics, it is now possible to collect additional metrics (emitted via EventCounters) for exporting in the Prometheus exposition format. You can configure dotnet monitor to collect additional metrics as shown in the example below:

November 10, 2023 - The Metrics API gets a snapshot of metrics in the Prometheus exposition format of a single process (the pid will be set through configuration). dotnet-monitor can read and combine configurations from multiple sources.
