Environment:
- APM 10.x- Windows, Linux/Unix
Cause:

The Errors Per Interval counter is entirely different than the Errors Tab. The data is coming from different data sources and is unrelated to each other.

 

Resolution:

- The Errors Per Interval metric counts real exceptions such as HTTP Errors(404,500),Network exceptions etc..
- Errors tab reports errors from Error Detector.
