Customizable solution that provides the ability to ingest alerts from different systems
The price could be cheaper. That was one reason why we switched to PagerDuty. We wanted to switch to something that provided the same features but at a lower cost. We also switched because PagerDuty provided other features like integration with ServiceNow and the scheduling of engineers. Evanios was only for event integration. Evanios created too much noise. For every alert, it would create an incident. We received too many alerts and incidents from monitoring. It wasn't able to intelligently ingest alerts. It created 4,000 incident tickets in a month, which didn't reflect what was happening. If we received an alert, the synthetic monitoring and volume drop would give us the same alert. Evanios should include alert ingestion and de-duplication of alerts and noise reduction. We couldn't have people resolving each and every incident. PagerDuty gives us reports on how many alerts are being ingested, how many are noise, how many have bigger incidents, and which of the alerts are creating noise. It would be helpful if Evanios had metrics on the amount of alerts and types of the alerts to show which ones were serious incidents and which ones were just noise.

A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Pros

"The ability to manipulate events via JavaScript getting the exact data that we want."
"So far, the amount of IT hours to maintain and support has dropped dramatically."
"Evanios has in some areas provided up to a 90% noise reduction in some our noisy monitoring tools."
"Provided up to a 90% noise reduction in some our noisy monitoring tools."
"Creation of incidents was previously a manual process with lots of copy and paste, swivel chair, mistakes, and missed events, and everything is now automated with events correlated and deduplicated, as well as crosschecks against scheduled change outages."
"Incredible ROI: As soon as we switched to Evanios, we started seeing events that were being unknowingly suppressed in our previous solution."
"The most valuable feature is the integration with various alert-generating systems because you may have synthetic alerts or monitoring alerts for volume drops."
"The most valuable feature is the integration with various alert-generating systems because you might have synthetic alerts or monitoring alerts for volume drops."

Cons

"There were initially some minor issues around domain separation in ServiceNow."
"More complex correlation rules would be nice. The ability to clearly define a parent event in a correlation and nested correlations, specifically."
"Evanios created too much noise. For every alert, it would create an incident."
"We would like the ability to have an "exit" option for events when they are being processed."
"The price could be cheaper."
"More complex correlation rules would be nice. The ability to clearly define a parent event in a correlation and nested correlations, specifically."
"System information and status (easy to read for all levels of IT) Clearer instructions on setting up alert notifications to support staff in the event of an issue with product: There are some instructions on their support site but I'm looking for something a little more detailed to understand the flow of events (expected compared to unexpected)."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
