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 Level: 1 Class: Bug fix Version: 1.4.0i1 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 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 Level: 2 Class: Bug fix Version: 1.4.0i1 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 8533: Fixed possible mixup of check results resulted by a timeout in a check helper

by Lars Michelsen

ID: 8533 Title: Fixed possible mixup of check results resulted by a timeout in a check helper Component: cmc Level: 2 Class: Bug fix Version: 1.4.0i1 When the check of a host resulted in a timeout, it could happen that the check helper which handled the time out was left in an unintended state making the next check timeout too early. This could result in the check helper / core communication being mixed up. As result one host could get the check results of another reported which mostly lead to an error message "ignoring check result for [host] / [service]: no such service".
