Products

Issue/Introduction

Errors Per Interval metric value does not seem to match with the errors reported in the Error Tab, as per below sample screen shots:

1. Errors Per Interval metric counts

2. Errors tab

 

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.

 

Environment

- APM 10.x, 2022.x - Windows, Linux/Unix

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.
