Attila Doroszlai commented on HDDS-7648:
----------------------------------------
[~xBis], I have checked UGI metrics with and without the patch. Two
observations:
# {{component}} is already available to distinguish between various servers.
Can you please clarify why it would be useful to add servername, too?
# The patch uses default port to determine the origin of metrics. This only
works with the default ports. Using custom ports results in "unknown"
servername.
Without patch:
