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.

Monitoring ease and cost-saving benefits enhance operational efficiency
The monitoring in OP5 Monitor is very easy because we can directly use custom plugins. We can write custom scripts and use those scripts directly. It's very low cost, open, and the dashboards are easy to see. We can extract the reports easily, and this is very easy to compare. Real-time monitoring in OP5 Monitor provides data every one minute or every five minutes, enabling us to get live data from the last one minute or last five minutes. OP5 Monitor gave us proper server availability, so we can always check whether a server goes down or the server CPU and memory decreases. Before reaching a particular bottleneck situation, we identified and fixed the issue, which helped us from a cost-saving business perspective. It helped us avoid application downtime.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"So far, the amount of IT hours to maintain and support has dropped dramatically."
"The most valuable feature is the integration with various alert-generating systems because you may have synthetic alerts or monitoring alerts for volume drops."
"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 might have synthetic alerts or monitoring alerts for volume drops."
"The ability to manipulate events via JavaScript getting the exact data that we want."
"Evanios has helped us reduce our incident count by about 60% in just three months into implementation and we are seeing great ROI right from the first month."
"The best feature is that it is very relatable, stable, and scalable. The logger is a part of the software, but it's not the most important point of it."
"Its open-source environment is accessible to everyone."
"The API makes it pretty easy to integrate with any system."
"With limited hardware or a virtual machine, you can address a huge network, hundreds of thousands of elements that need to be monitored. Other commercial software is not on that level."
"The monitoring in OP5 Monitor is very easy because we can directly use custom plugins; we can write custom scripts and use those scripts directly, it's very low cost, open, and the dashboards are easy to see."
"Instead of checking the logs each Monday, or checking that applications are running, and checking your ticketing system for angry users, you put this system in place and it monitors and continuously tests everything that is of importance to you and your users."
"The best feature is that it is very relatable, stable, and scalable."
"OP5 Monitor is a great choice due to its being built on an open-source monitoring tool and provides ample opportunity for customization based on specific support requirements. It is also user-friendly and easy to manage with a wide range of plugins available for use. In comparison to other enterprise tools, such as Micro Focus, OP5 Monitor stands out for its features and cost-effectiveness, making it the best tool in the market. Customization is one of the key strengths of the tool and provides a lot of capabilities. Additionally, it is easy to find support and plugins for the tool through online resources."
 

Cons

"Evanios created too much noise. For every alert, it would create an incident."
"More complex correlation rules would be nice. The ability to clearly define a parent event in a correlation and nested correlations, specifically."
"There were initially some minor issues around domain separation in ServiceNow."
"We would like the ability to have an "exit" option for events when they are being processed."
"The price could be cheaper."
"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)."
"More complex correlation rules would be nice. The ability to clearly define a parent event in a correlation and nested correlations, specifically."
"OP5 Monitor could include application monitoring in addition to infrastructure monitoring. If application business transactions were monitored, it would be helpful."
"OP5 lacks some visualization, a feature that makes some other products nice. Op5 is built for purpose, which is fine, but if you compare it with some new products, the visualization is not so appealing, especially for management... If you don't need fancy visualizations, OP5 is fine."
"IT environments today are in constant flux. This is driven by the newer cloud technologies such as Kubernetes and Docker, etc. The whole Nagios-based monitoring system that OP5 is created on top of, is based on a host-service model. There is a need for a strategy on what to do with more dynamic environments."
"We do not get performance reports properly, which needs improvement."
"We do not get performance reports properly."
"The user interface is not what we are used to these days, and should be improved."
"The solution is useful for tweaking. However, there have been some negative experiences, such as limited report capabilities. The only report available is in PDF format, making it difficult for teams managing multiple servers to extract data in Excel format. The speaker recommends that the team improve the report capabilities to better serve users."
"IT environments today are in constant flux. This is driven by the newer cloud technologies such as Kubernetes and Docker, etc. The whole Nagios-based monitoring system that OP5 is created on top of, is based on a host-service model. There is a need for a strategy on what to do with more dynamic environments. There is some cool stuff going on in that direction."
 

Pricing and Cost Advice

Information not available
"It was not expensive. And because it's less demanding in terms of hardware, you don't have to pay for another SQL or other database license, and you can have a huge installation on one machine..."
"The cost of the license and support are separate. If you want platinum call support, it will cost more than a regular call. I did not opt for it, as it is an additional cost."
"OP5 has a very low price as a solution, compared to many other solutions out there."
