Monitoring and Alerting Infrastructure (MAI) –
Calculation Engine Framework using “Hot Table”
New Framework with Improved Performance
You are using System Monitoring within SAP Focused Run to monitor a large landscape of systems. The job SAP_ALERT_CALCULATION_ENGINE (calculation engine) which calculates all the System Monitoring alerts is scheduled every minute. The calculation is quite performance intensive causing a heavy load on the HANA database.
Besides the job either sporadically or regularly might be taking more than one minute to complete causing a delay in the alert creation process. This document describes the technical background, the architecture of a new approach improving the performance and includes also a how-to section explaining how to activate and if needed also deactivate the new framework.
