RG Solutions Capacity Management reporting provides assurance that IT can meet current/future Business needs in a cost effective manner and lets the business know when IT investments will need to be made.

In fact, Capacity Management reporting is core to Service Delivery because if your systems are out of capacity there’s little point trying to agree on service levels etc as they’ll probably never be realized.

As with Service Level reporting, our approach to Capacity Management reporting takes a look at capacity from the perspectives of Interactive (online) and Update (Batch) processing workloads but in the context of the Server rather than the Service.

Interactive processing is generally a transaction driven workload and you need to ensure there is sufficient capacity to service transactions within the agreed service level agreement (SLA). Capacity of interactive workloads is therefore measured on the peak processing interval.

Update processing requires the opposite in that the CPU’s should be 100% utilized in order to turn around processing in the shortest possible time. Therefore, capacity is measured using batch elapsed times.

In the following examples, you will see some illustrations of how RG Solutions can be used for Capacity Management reporting.

Interactive Capacity Management

The real time transaction services for this bank are provided on a number of different platforms. The capacity required is based upon the peak load for each individual server. The ATM Wintel servers are clustered for contingency purposes. The IBM i5 server shaded in red is running at 100% of capacity and requires urgent attention.

Interactive Capacity Management Trend

As the IBM i5 system was in need of urgent attention, a trend report was used to review the growth over the previous 12 months.

The report shows a period of steady growth over the first half of the year but from August there was a sudden step change. This happened when new functionality was introduced into the online service. The additional processing effectively reduced the lifecycle of the server.

Update Capacity Management

The overnight processing capacity usage also needs to be taken into account for this bank. If this overruns, it will impact on the real-time service availability. The server shaded in red is critical, although the processing shows it could have been started 90 minutes earlier.
