Service Level Objectives (Summary)
The following service level objectives are defined in this SLA. Each objective is listed with its weight and the percentage of fulfillment. The fulfillment is the relationship between the weight and the compliancy of the Quality of Service constraints defined within the SLO.
State Objective Description Weight (%) Achieved (%) Expected (%)
up.png HQ - Database Server The database server and its application data is a critical component of this e-commerce service. Monitoring the performance of its functional subsystems and sql query response times in support this SLA is important to ensure continuous SLA compliance. auto 99.83 99.00
