Check_MK Werk 8538: Make graph data resolution visible in the graphs

by Lars Michelsen

ID: 8538 Title: Make graph data resolution visible in the graphs Component: Metrics System Level: 1 Class: Bug Fix Version: 1.2.9i1 It was not transparent to the users which data resolution the graphs are calculated and rendered with. The step of the graphs is now rendered to the top right of the graphs, next to the time specification to make this transparent.

Check_MK Werk 8611: Alert handlers now log success or failure to monitoring history

by Mathias Kettner

ID: 8611 Title: Alert handlers now log success or failure to monitoring history Component: Alert Handlers Level: 2 Class: New Feature Version: 1.2.9i1 Alert handlers to send feedback to the monitoring core. The history of the affected host or service now gets two log entries: one for the launch of the handler, one for the termination. Also two identical alert handlers will not be allowed any longer to run in parallel. This will avoid flooding processes in case of hanging handlers.

Check_MK Werk 8539: Made consolidation of values transparent to the user

by Lars Michelsen

ID: 8539 Title: Made consolidation of values transparent to the user Component: Metrics System Level: 2 Class: Bug Fix Version: 1.2.9i1 When showing graphs of larger time ranges, the graphs are normally based on aggregated values, which means multiple measured values are consolidated to a single value. For example, when a graph is based on the "max" aggregation function, like nearly all graphs are by default, the values in the Average column are not the real average values of the shown time, but the average values of the max values in the step of the graph. The step of the graph is now shown on the top right of the graph. To clarify this: If you look at a 7 day graph, you have a step of 30 minutes. If the service is being checked in a 1 minute interval, the graph is based on the maximum of 30 single values of each 30 minutes step. So your average values are the 7 day average of the 30 minute maximum values. This is obviously not what most users would expect, but we would have to fetch 3 times more data per graph to get the real average and the real min values for each graph. The graphs are already producing a lot of load and we try to keep the impact low, so we decided to make the calculation transparent and changable by the user. If you have a max graph, the min and average columns are slightly grayed out to visualize the situation. If you hover on the titles, you get a description about it. Now you can click on the columns titles to change the aggregation function the graph is based on.

Check_MK Werk 8570: Make PROCESS_HOST_CHECK_RESULT's behavior more Nagios-like

by Sven Panne

ID: 8570 Title: Make PROCESS_HOST_CHECK_RESULT's behavior more Nagios-like Component: The Check_MK Micro Core Level: 1 Class: Bug Fix Version: 1.2.9i1 The Nagios documentation for the external command PROCESS_HOST_CHECK_RESULT explicitly states that the return code in the commandline is already the host state, not the result code of a check result (which was the core's previous interpretation). We follow Nagios now more closely and map the return code in the commandline as follows: 0 => UP 1 => DOWN/UNREACHABLE (previously this meant UP, too) 2 => DOWN/UNREACHABLE We still deviate a bit from Nagios, because the actual decision if a host is DOWN or UNREACHABLE is done by the core and can't be overridden from the outside.

Check_MK Werk 8541: Service checks timeouts can now be configured individually for services

by Lars Michelsen

ID: 8541 Title: Service checks timeouts can now be configured individually for services Component: The Check_MK Micro Core Level: 2 Class: New Feature Version: 1.2.9i1 It is a good idea to keep the service check timeout values as low as possible. All past versions could only configure this option globally. So if you had only some services needing a higher execution time, you had to increase this global value for all your services. Now you can use the rule set "Service check timeout (Microcore)" to control this timeout per service. It will override the globally configured option for all matching services.
