Statsbeat in Application Insights

  • Article

Statsbeat collects essential and nonessential custom metrics about Application Insights SDKs and autoinstrumentation. Statsbeat serves three benefits for Azure Monitor Application Insights customers:

  • Service health and reliability (outside-in monitoring of connectivity to ingestion endpoint)
  • Support diagnostics (self-help insights and CSS insights)
  • Product improvement (insights for design optimizations)

Statsbeat data is stored in a Microsoft data store. It doesn't affect customers' overall monitoring volume and cost.

Statsbeat doesn't support Azure Private Link.
