Last Updated:Jul 27, 2023

Issue

Why do I initiate multiple requests but generate a small number of trace calls?

Possible cause

The number of traces depends on the specified sampling rate.

You can view the sampling rate in the ARMS console. Navigate to the Sampling rate setting section on the Custom Configuration tab of the Application Settings page. The default sample rate 10% indicates that only 10% of traces are collected.

Sampling rules:

  • By default, traces of abnormal calls and calls that encounter errors are collected.

  • By default, traces of slow calls are not collected.
