Checkmk Werk 14550: <tt>mk_logwatch</tt> via bakery: Add <i>APPEND</i> option for message classification

ID: 14550 Title: <tt>mk_logwatch</tt> via bakery: Add <i>APPEND</i> option for message classification Component: agents Level: 1 Class: Bug fix Version: 2.2.0i1 The <tt>mk_logwatch</tt> agent plugin can be deployed via the agent bakery (ruleset <i>Text logfiles (Linux, Solaris, Windows)</i>). In this ruleset, users can specify regular expressions for processing log messages. Before this werk, users could specify regular expressions to classify messages (OK/WARNING/CRITICAL), to ignore messages and to rewrite messages. As of this werk, users can additionally specify regular expressions to combine multiple log lines into a single message via the APPEND option, see the help of the bakery ruleset for details. One use case for this is the processing of multi-line stack traces. Note that this feature was already supported by the <tt>mk_logwatch</tt> agent plugin before this werk, but it was not configurable via the agent bakery.
