 - **Applications**: Application Insights creates metrics for your monitored applications to help you detect performance issues and track trends in how your application is being used. Values include _Server response time_ and _Browser exceptions_.
 - **Virtual machine agents**: Metrics are collected from the guest operating system of a virtual machine. You can enable guest OS metrics for Windows virtual machines by using the [Windows diagnostic extension](../agents/diagnostics-extension-overview.md) and for Linux virtual machines by using the [InfluxData Telegraf agent](https://www.influxdata.com/time-series-platform/telegraf/).
 - **Custom metrics**: You can define metrics in addition to the standard metrics that are automatically available. You can [define custom metrics in your application](../app/api-custom-events-metrics.md) that's monitored by Application Insights. You can also create custom metrics for an Azure service by using the [custom metrics API](./metrics-store-custom-rest-api.md).

The Metrics Dataplane API is a high-volume API designed for customers with large volume metrics queries. Similar to the existing ARM metrics API, it provides the capability to retrieve metric data for up to 50 resource IDs in the same subscription and region in a single batch API call, improving query throughput and reducing the risk of throttling. The current metrics API is the most queried API in ARM API, but customers who leverage it for bulk queries at high frequency and push metrics to other datastores for deep analytics may experience throttling issues. The Metrics Dataplane API provides higher query limits to address these issues and enable customers to query metrics without the risk of throttling. Customers can learn more about this API by visiting the link provided.
