Expose timing information in GELF output #3716

Open kroepke opened 7 years ago

kroepke commented 7 years ago

The GELF output currently does not track detailed histogram information about its timing.

This makes it difficult to identify throughput problems when forwarding to other systems. At last the process time should be tracked, better yet a HDR histogram.

Reopened because we had to revert #3810 due to backwards compatibility.

A backwards compatible way to gather output metrics could be implemented in the OutputProcessor.
