4.1.1 Traffic-light SLA
Traffic-light SLA compliance table shows single values for each selected elements (access
points or links). The color of the table shows if an element meets the performance target.
4.1.2 SLA Compliance over time
In the picture below, there are three network elements, AP-14, AP-16 and AP-17. Based on the
chart one can assume that AP-14 is operating as expected. On the other hand, the other
elements seem to be occasionally below the SLA compliance target. Note that AP-16 might be
completely out (during pointed time) or some KPI does not meet the target threshold.
While all elements would benefit from some attention, it is obvious that AP-16 should have
the priority. This is elementary to the SLA compliance KPI: one glimpse tells whether some
element needs attention or not. The nature of the problem is available through investigating
SLA single element chart or more detailed metrics’.
