Checkmk Werk 7489: mk_logwatch: optimize regex search

ID: 7489 Title: mk_logwatch: optimize regex search Component: Checks & agents Level: 1 Class: New feature Version: 1.7.0i1 For regular expressions in a logwatch section leading or trailing '.*' portions can be a performance desaster. With long log lines, it can virtually render your system paralyzed. If you are not using any rewrite patterns though, you can omit leading and trailing '.*' expressions without changing the set of matched lines. mk_logwatch now detects those cases, and will optimize the patterns accordingly.
