Transition to using connection strings for data ingestion by 31 March 2025

Published date: March 21, 2022

On 31 March 2025, technical support for instrumentation key–based global ingestion in the Application Insights feature of Azure Monitor will end. After that date, your Applications Insights resources will continue to receive data, but we'll no longer provide updates or customer support for instrumentation key–based global ingestion.

Application Insights is changing from global ingestion endpoints to regional endpoints that use connection strings, which provide these additional capabilities:

  • Authenticated telemetry ingestion.
  • Regional data residency.
  • Endpoint customization for intranet or hybrid environments.

Recommended action

To continue getting technical support related to data ingestion for your Application Insights resources, transition to connection string–based ingestion before 31 March 2025.
