Service Uptime Summary report

Service Uptime Summary report overview

The Service Uptime Summary report shows uptime information for a service. Service Uptime Summary is the percentage of time that the service was completely up, factoring in outages.

The default display is a table showing outage information. Only SAP and SDP outages are displayed. Overlaps of SAP downtime and SDP downtime are considered in total downtime and percentage uptime calculations.

For example, if the SAP was down from 10:00 to 11:00 and the SDP was down from 10:30 to 11:30, then the overlap of 10:30 to 11 would be considered only once. The total downtime in this case would be 1:30:00 hours. Uptime % would be calculated based on this downtime.

Uptime % is calculated by the events recorded in the assurance_assuranceEvent Table. The current state of the service is taken from the currentState field of the Service table.

Uptime is calculated as follows:

Uptime = (Total Time) – (Time for which the SAP or Service was down)

Uptime % = (Uptime/Total Time) * 100

Use cases
