ENHANCE, MAINTAIN, AND SUSTAIN CMS ENVIRONMENT (INNOVATION)

Application monitoring and alerting: We propose innovative approaches for automated monitoring and alerting of the CMS application by incorporating alerting procedures into the code. The benefit of this approach is that problems are proactively discovered before the CMS end users experience or reports them. For all new change requests and enhancements, we will consider the application monitoring, thresholds, alerting requirements as early as the Software requirements/development stage and incorporate these checks into code review. We will use the existing instrumentation and Tivoli Enterprise Console (TEC) alert mechanism to integrate application monitoring and alerting.

Predictive analytics for maintaining high availability and reliability: We propose predictive analytics for preventing expensive outages. Our approach includes correlation of business, technical, and historical CMS events/trends to predict potential issues by correlation of business issues (performance, slowness, or outages) and historical trends. The benefits include improved operational efficiency of the applications, reduced tickets, and minimized MTTR/increased MTBF, resulting in high availability.
