Aled Sage resolved BROOKLYN-576.
--------------------------------
Resolution: Fixed
> Excessive debug logging
> -----------------------
>
> Key: BROOKLYN-576
> URL: https://issues.apache.org/jira/browse/BROOKLYN-576
> Project: Brooklyn
> Issue Type: Bug
> Reporter: Aled Sage
> Priority: Major
>
> There is excessive (debug) logging in Brooklyn.
> As an example, I took a QA test that deploys a medium-sized blueprint, runs a
> few assertions against it, and tears it down (within an hour). That test has
> 280,724 lines at debug or above. As another example, in a long-running
> Brooklyn server the debug log rolls frequently (with 10 rolling log files of
> 100MB each, we have only 9 hours of logs).
> Taking that first example, here are a few counts of line numbers that appear
> a lot.
> There are 3352 lines during startup of the form:
> {noformat}
> 2018-01-16T10:18:39,356 DEBUG 120 o.a.b.c.b.s.c.BrooklynEntityMatcher
