Checkmk Werk 7938: Unify status table columns in NEB and CMC.

by Sven Panne

ID: 7938 Title: Unify status table columns in NEB and CMC. Component: Livestatus Level: 1 Class: New feature Version: 1.7.0i1 <ul> <li>Added <tt>average_latency_cmk</tt> and <tt>average_latency_real_time</tt> columns, always containing zero.</li> <li>Added <tt>average_latency_generic</tt> column, containing the average latency of all active host/service checks.</li> <li>Added <tt>core_pid</tt> column as an alias for <tt>nagios_pid</tt>.</li> <li>Added <tt>has_event_handlers</tt> column.</li> <li>Added <tt>helper_usage_generic</tt>, <tt>helper_usage_cmk</tt>, and <tt>helper_usage_real_time</tt> columns, always containing zero.</li> <li>Added <tt>livestatus_overflows</tt> and <tt>livestatus_overflows_rate</tt> columns. The NEB queues accepted connections, so we never have overflows here. Nevertheless, we provide these columns for consistency with CMC, and they always contain zero.</li> <li>Added <tt>livestatus_usage</tt> column.</li> <li>Added <tt>num_queued_alerts</tt> column, always containing zero.</li> <li>Added <tt>num_queued_notifications</tt> column, always containing zero.</li> <li>Removed <tt>livecheck_overflows</tt> and <tt>livecheck_overflows_rate</tt> columns from both NEB and CMC. They were unused for more than 6 years, they never really worked well, and simply contain zero for ages. To reduce confusion, those columns are gone now.</li> </ul>

Checkmk Werk 7978: Service labels can now be discovered

by Lars Michelsen

ID: 7978 Title: Service labels can now be discovered Component: Core & setup Level: 2 Class: New feature Version: 1.7.0i1 The discovery functions of Checkmk checks can now produce a collection of service labels together with the discovered services. This makes it possible for the check developer to mark the services of the discovered services which can then be grouped together in a flexible way. The discovered service labels can be listed on the service discovery page of WATO by enabling them with the button "Show discovered labels". These labels are attributes of the discovered service and will be handled exactly like them. They are discovered in one step and applied to the running configuration in the same way. The cluster handling is also equal. How make my checks produce service labels? Instead of producing a two element tuple of <tt>(item, parameters)</tt> to create a new service the discovery functions can now provide objects like this: C+: Service( item="Interface 213", parameters=None, service_labels=ServiceLabels( ServiceLabel(u"check_type", u"network_interface"), ServiceLabel(u"interface_type", u"uplink"), ) ) C-: These objects can be returned / yielded like the tuples before. Both, the parameters and the service_labels are optional arguments.
