7signal Sapphire Loupe User Guide Release 3.1
5.1 Three-basket principle
The color-coding indicates the SLA status, it may be either red, yellow or green. The wlan
network may be operational and any test and any user-action may be successful yet the color
in the SLA table is yellow or even red. This is because SLA view is highly derived data that is
compared to expected level of the service.
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.
