Not following the standard log format

[breezewish]

Example:

./ng-monitoring-server
2021-11-30 21:10:22.028505 I | Failed to initialize config, err: unexpected empty pd endpoints, please specify at least one, e.g. --pd.endpoints "[127.0.0.1:2379]"

Some outputted log format is not following the standard log format as well, like:
