Event correlation is the process of aggregating events and analyzing relationships between them in order to “reduce the noise.” It is a response to “alert fatigue” caused by IT sprawl (the volume and complexity of infrastructure and applications) and the reality that most enterprises have deployed numerous monitoring tools. Something needs to collect information from these disparate sources then refine the incoming information to make it understandable and actionable – providing IT Operations and monitoring teams with the ability to “See the forest through the trees.”
The technique has been around long enough that it almost became an afterthought. “Keeping the lights on” isn’t a sexy concept to executive stakeholders who are primarily focused on concerns such as cloud computing, security, mobile, etc. However, the emergence of machine learning and IT Operations Analytics (ITOA) is creating an event correlation renaissance – better automation and deeper insights (including warnings about events that haven’t even happened yet) are dramatically lowering costs and improving efficiency, resulting in a lighter load on the Service Desk, fewer service interruptions and faster response time.
If you are looking for a modern event correlation engine, below are some of the key attributes you should consider.
Collaboration on a unified platform allows IT Operations and Support teams to dramatically improve event management. “Noise” can be managed and reduced on the front end by automatically provisioning monitoring when a new device is added to the CMDB, and/or automatically suppressing event noise during planned changes. Additionally, events can be enriched with ITSM data to improve root cause analysis and trigger automated remediation.
Best practices include the normalization of source data into a common event format (which allows you to report and take action on similar events while maintaining all original detail), and filtering unwanted events close to the source. Correlation based on a mixture of CMDB topology, time, and event content will give you the most flexibility and accuracy.
Enterprises do not want to custom code their event management solution (there are too many moving parts) so an out-of-the-box, tunable solution that evolves with your business requirements and accommodates 0-day events (or unique scenarios) is preferable.
Can you proactively calculate service impact and identify leading indicators in real-time? Extensible algorithms will allow you to immediately determine severity and continuously improve scoring accuracy.

“We have the challenge of making sure that we become much more proactive. AI and the capabilities of Evanios are absolutely critical.”
Charles Araujo Analyst, Intellyx
“Built upon the ServiceNow platform, the Evanios approach is to fully integrate event management, automated incident resolution, predictive analytics and monitoring directly into a unified workflow. The result is an intuitive and seamless model that enables IT organizations to move past the arbitrary separation between event and incident management and instead focus on the management of services from a business value perspective.”
Steele Smith Senior Systems Engineer, Cox Enterprises
“Working in the event management space for well over a decade, I can honestly say that I have never had a product integration go so smoothly and perform exactly as expected. The Evanios integrations and event management products have been the absolute best products I’ve encountered and a pleasure to use.”
Tony Taylor Sr. Director Infrastructure & Security, Land O’Lakes
“With Evanios’ integrated ServiceNow solution we’ve made more significant process than ever before.”
John Bitzer Global Service Management Tools, AstraZeneca
“Evanios filters, de-duplicates and correlates events so well that we are seeing exactly what we hoped for: reduced incidents, fewer tickets, better routing and far greater accuracy resulting in much better response rates.”
