SLA Monitoring and Forecasting for TWS for z/OS and End-To-End
TWSemon SLA Realtime Forecast fulfills an essential requirement to proactively determine business services that are at risk of missing agreed service levels. Batch processes under TWS for z/OS can now be managed in a more professional way. Reliable information replaces professional estimates for higher accuracy, predictability and manageability of your mission critical batch processes.
TWSemon SLA Realtime Forecast allows the definition of a service and a time when this service needs to be completed by (SLA point). At regular intervals it calculates the expected completion time for a defined business service running under TWS for z/OS. The impact of errors or delays in a defined business service will then be recognized by TWSemon SLA Realtime Forecast and potential delays that could put the agreed service levels under risk are flagged before the business is adversely impacted. Corrective actions can be taken with the standard TWSemon functionality.
Based on the defined services and SLA points critical services are listed with their expected or real completion times and the SLA points. Those services which could not be completed within the agreed SLA points, or which most likely will fail to meet future SLA points, can easily be identified. On the basis of:
historical runtime data collected by the TWSemon SLA Realtime Forecast over time,
the structure of the Current Plan and
the planned start- and end-times calculated by TWS for z/OS
TWSemon SLA Realtime Forecast will create a basis for the real-time forecast calculation. At a defined interval, the SLA real-time forecast calculator recalculates the plan basis considering all status changes in the Current Plan. Structural changes in the Current Plan, like the addition of a triggered application (ETT) will also be considered in the calculation.
