Sampling override with http.response.status_code doesn't work

[zwilling79]

Expected behavior

If you add a sampling override that filters out all requests with a specific HTTP response status, those requests shouldn't be shown in Application Insights.

Actual behavior

HTTP requests with the specified status code are shown in Application Insights.

To Reproduce

• Create a simple Spring Boot application with the health actuator endpoint enabled
• Create a applicationinsights.json that includes the below sampling setting:

  "sampling": {
    "percentage": 100,
    "overrides": [
      {
        "telemetryType": "request",
        "attributes": [
          {
            "key": "http.response.status_code",
            "value": 200,
            "matchType": "strict"
          }
        ],
        "percentage": 0
      }
    ]
  },

• Do a GET request to the http://localhost:8080/actuator/health endpoint
  • It should return a 200 response code with the following payload: { "status": "UP" }
  • This request shouldn't be shown in Application Insights
• Do a GET request to the http://localhost:8080/actuator/invalid endpoint
  • This request should be shown in Application Insights because you get a 404 error
