5 SERVICE LEVEL AGREEMENT, SLA
The service level agreement (SLA) view contains KPIs that display network functionality and
availability as traffic lights.
The default limits are set by 7signal, and the values are based on real-life situations. You can
modify the values to conform to the service level agreement currently being used. The values
can be modified in the Sapphire Carat’s management interface.
The SLA view contains by default the following KPIs:
AP attach success rate
IP retrieval success rate
AP beacon availability
Ping success rate
FTP downlink throughput
FTP uplink throughput
MOS downlink
MOS uplink
Ping RTT
FTP test success rate
VoIP test success rate
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.
