Hello
By testing with 2 and 3 KPI´s and different severities and importances i have gotten the following formula:
N = count of KPI´s; G = importance of one KPI; K = the severity of the KPI (normal=100, low=70, medium=50, high=30, critical=0)
(I have gotten the factors of the different severities by testing)
Here an example:
Service Health Score = (100 ∗ 10/22)+(70 ∗ 7/22)+(30 ∗ 5/22) = 45,45 + 22,27 + 6,81 = 74,53
So far so good, but I do not know how service dependencies are considered in this calculation, since you can not adjust their importances directly. My idea is, that the KIP´s of the other services are handled like it would be the own ones. Does anyone has an idea?
Regards
Benjamin
