1 Title: It is now possible to sort by the perfometer column
10 The service list status views of Check_MK can now be sorted by the column "Perf-O-Meter".
12 The sorting of the perfometers is sorted by these values:
15 <li>First sort by the optional perfometer group or perfometer ID</li>
16 <li>Second sort by the sort value of each perfometer</li>
19 <strong>The Perfometer group / perfometer ID</strong>
21 Each perfometer declaration can have an optional element <tt>sort_group</tt>. This element
22 holds a string that can be used to group different perfometers (that visualize comparable values)
25 In case no <tt>sort_group</tt> is defined, the internal ID of the perfometer definition is used.
26 This means that all perfometers which are rendered by the same logical function are sorted together
27 in a perfometer group.
29 <strong>The sort value</strong>
31 The sort value of a perfometer is calculated in different ways for each perfometer type based on
32 the current metrics of this service.
35 <li><i>Logarithmic</i>: The single logarithmic value displayed by this perfometer is used</li>
36 <li><i>Linear</i>: The first segment of the displayed values is used</li>
37 <li><i>Stacked</i>: The sort value of the first stacked perfometer is used</li>
38 <li><i>Dual<i>: The maximum of both displayed value is used for sorting</li>
41 The sorting only works for perfometers that are implemented as metric plugin
42 (in <tt>plugins/metrics/</tt>). The legacy perfometers that are implemented as perfometer
43 plugins can not be sorted.
45 Dear check developers: All perfometers that visualize equal types of values have to be
46 sorted together in a sort group. For example all checks that monitor fileystems should have
47 equal perfometers that can be compared to each other and should therefor be sortable by their
