The threshold value for KPI.
Green level
99,0%
At least 99,0% of measured samples must attain
an upload throughput of at least 5,5Mbit/s in
order to attain the green level for the KPI in
question.
Yellow level
95,0%
If the percentage of measured samples that
satisfy the boundary value criteria falls between
95,0% and 99% the yellow level is attained.
Red level
below 95,0%
If the percentage falls below 95,0% the service
level can be considered unfulfilled.
19.3 Creating an SLA group
An SLA group can be created in one of two ways:
1. By copying an SLA template
2. By creating an empty SLA group and adding to it the desired Key Performance
Indicators
When the desired set of KPIs has been added to the SLA group the KPI boundary values can be
set to match the service levels outlined in the actual Service Level Agreement contract.
