Statsbeat in Application Insights
In many instances, Azure Monitor Application Insights automatically collects data about product usage for Microsoft through a feature called Statsbeat. This data is stored in a Microsoft data store and doesn't affect customers' monitoring volume and cost. Statsbeat collects essential and nonessential metrics about:
- Azure Monitor OpenTelemetry Distros
- Autoinstrumentation (automatic instrumentation)
- Application Insights SDKs (Classic API)
The three main purposes of Statsbeat are:
- Service health and reliability - Monitoring the connectivity to the ingestion endpoint from an external perspective to ensure the service is functioning correctly.
- Support diagnostics - Offering self-help insights and assisting customer support with diagnosing and resolving issues.
- Product improvement - Gathering insights for Microsoft to optimize product design and enhance the overall user experience.
Note
Statsbeat doesn't support Azure Private Link.
