Application Insights Agent

The agent uses the configuration /docker/applicationinsights.json. By default, the sampling is enabled

• dependency: 5%
• trace: 5%
• exception: 100%
• request: 100%

If you want to customize the agent you can add your file in the Dockerimage

FROM ghcr.io/pagopa/docker-base-springboot-openjdk17:v2.1.2@sha256:824a241756a32ac9eeef4585a3a266fb019d2c599337269b0c8b419de4c2df3e
