Comprehensive and mature monitoring solutions, where many IT elements that comprise a business service, can lead to a further issue – an ‘event storm’.
With the complex and integrated nature of IT application delivery today, degradation in application availability and performance can lead to a cascading flood of events throughout the enterprise monitoring solution.
Event correlation technologies and approaches exist to simplify and consolidate event management, improve overall performance and availability and to reduce operational costs by combining predictive analytics, automation and traditional event and service impact management capabilities into a single platform.
There are two major approaches; rule based correlation in which a defined set of rules is applied on top of incoming events in order to link to related events; and topology based correlation in which leverages the known relationships stored in a CMDB in order to map them related events and services.
Implementation of mature event correlation solutions should lead to:
- Increased operational efficiencies and lower costs through a single platform for enterprise event, impact, and availability and performance management.
- The ability to focus on outage avoidance through predictive root cause.
- Reduction in Mean Time To Repair (MTTR) and increased service level compliance.
- Minimisation of service disruptions to the business through predictive correlation and dynamic prioritisation of events across multiple technologies, platforms, vendors and sources.
- Driving additional value through automating ITIL processes and workflows across your enterprise monitoring and ITSM solutions.
