Problem Description

After upgrading to 2.1.17 from 2.1.16, our log verbosity has increased dramatically, with no change to the configured log level.

What is actually happening

With version 2.1.16 our average log lines per event (after parsing with jq) was about 35 lines. After upgrading to 2.1.17 each event is now ~800 lines, an increase of roughly 2,285%.

After noticing this, we've tried decreasing the log level to info but it made no difference.

How can we reduce the verbosity of these logs?

What is the expected behavior

  • a patch upgrade should not change behavior so dramatically, and
  • changing the log level should result in a different level of logging

example log event with 2.1.16:
