Checkmk Werk 15536: IPMI sensors: consider sensor state as reported by freeipmi

ID: 15536 Title: IPMI sensors: consider sensor state as reported by freeipmi Component: Checks & agents Level: 1 Class: New feature Version: 2.3.0b1 This werk changes the way Checkmk derives the state of IPMI sensors from their status descriptions. Previously, Checkmk would first check the user configured parameters (<i>IPMI sensors -> Set states of IPMI sensor status texts</i>), and then fall back to built-in heuristics to derive the service state from the sensors status description. These heuristics missed a lot of possible "OK" states, and thus produced false positives. This situation is improved by using the sensor status interpretation provided by <tt>freeipmi</tt>, if present. The order of preference is: Use the first matching user configured state, if found. Otherwise use the status as reported by <tt>freeipmi</tt>, if it is present. If neither of these can be applied, still fall back to the built-in heuristics. In order to get the <tt>freeipmi</tt> status reported by the agent, you need to select <i>"Sensor state"</i> in the rule set <i>"IPMI Sensors via Freeipmi or IPMItool"</i>.
