Updated logging regarding new masters. #510

Closed armandgrillet closed 5 years ago

armandgrillet commented 7 years ago

The detection of new masters now results in a log line that is displayed even with a disabled verbose mode.

The idea behind this change is that this event is important and not common thus it should be logged as such.

I'm pretty sure that, at one point, very-verbose logging was enabled for mesos-dns on dc/os. I took a peek at the dcos config scripts and also observe that any "verbose" logging appears to be completely disabled. I wonder why? (Too noisy in larger clusters?)

@jdef I have created https://jira.mesosphere.com/browse/DCOS_OSS-1880 to report the verbose mode issue. This PR is the result of a customer issue where having verbose logging would have been quite useful.

I do not think that this PR is dependent of DCOS_OSS-1880. If reviewers agree that an event such as new masters deserve more than a very verbose log line, it should be able to be merged.

LGTM

Just rebased. Should be merged if CI passes
