For example, one may get 100% VoIP calls through but the SLA shows red. The interpretation
here is that while the wlan network provides the VoIP service continuously, the service level is
not met, thus the alarming color-code. There are not necessarily imminent problems with the
wlan network in case red or yellow color but further investigation is surely needed. And
obviously it is possible that in case of the red color, the service may be completely down.
5.2 SLA table active cells
To better understand the resulting color-code the cells in the table are active. By clicking a cell
one gets immediate information on data that lead to the cell color.
In case further analysis is needed, the link “Related KPIs” pop additional KPI charts up. The
charts show a set of KPIs on time-interval that has shown on SLA table row expanded with one
unit earlier and later. If the SLA table row is for an hour, the KPI chart includes the preceding
and the following hour, too.
The set of KPIs either directly affect the SLA result or would be the KPIs that should be checked
in the next step of the analysis. The troubleshoot cases at the end of this manual elaborate on
the flow of analysis.
