In the last blog we talked about outages. Here we will discuss on how the outages can be processed.

 

Outages can have statuses like:

 

New – indicates newly created outages

In Process – being worked up on by an IT employee who is enriching or adjusting the outage details

To be reviewed – once the data is enriched, data is verified before it is confirmed

Confirmed – these outages are part of availability reporting

Rejected  – not considered for reporting

 

Service Availability is a result of all outages which happened during the related reporting period until current day of current reporting period, but occurred outside the agreed Contractual maintenance period.

 

How Service Availability is measured

TA        Technical Availability

DH       Total of all downtimes measured in hours per month.

SDH     Total of all agreed and scheduled downtimes, plus any downtimes outside the control of SAP, measured in hours per month

TH        Total hours per month

 

Here is an example to illustrate the calculation :

Contractual Maintenance Period(not SLA relevant):

  1. a)      „Maintenance Weekend“ on 3.16 time 08:00 – 18:00 ie.,   600 -> = 600min
  2. b)      „Regular Contractual Maintenance period“: on  8.3.16 time 07:00 – 11:00 -> 240 min

 

Unplanned outage(SLA relevant)

  1. c)       „ABAP System Availability“ 02.3.2016 6:42 – 8:57 = 135 min

 

DH = Total of all Downtimes 975 Min (a+b+c)

SDH = 840 Min (a+b)

TH = March = 31 days = 744h (=44640Min)

 

TA= (1- (975min-840min)/44640min) = 99,69% for the system in march

 

Here is a typical system availability chart :

 

With that we come to a close of this series. Now you can try out the Service Availability Management in your landscape to benefit from transparent reporting.
