Checkmk Werk 13710: <tt>oracle_instance</tt>: Handle unresponsive databases and login failures correctly

ID: 13710 Title: <tt>oracle_instance</tt>: Handle unresponsive databases and login failures correctly Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 In case of unresponsive databases or login failures, the check plugin <tt>oracle_instance</tt> went UNKNOWN and reported "Item not found in monitoring data". Instead, the plugin now goes CRIT and reports "Database or necessary processes not running or login failed". This also covers the case where a process which is needed to monitor the databases is not running (e.g. <tt>ora_pmon</tt>).
