Application performance and System monitoring at Agos

A reasonably priced tool for system and application monitoring

The main room for improvement is in the solution's presentation and the integration area. In our company, we use the integration capabilities from ServiceNow. We also have another big monitoring solution in place in our company, which is Dynatrace. At the moment, there doesn't exist an out-of-the-box integration for Dynatrace. I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most. The only implementation of Checkmk that allows high availability is the virtual appliance that has the option for the availability of a different box. Otherwise, you have to find a way to implement it manually with some custom solution, which could be an improvement.

Cons

"If an alert is generated for a specific pattern in the log, and if Checkmk catches that log, it will stay there even after the alert is resolved."

"Checkmk does not allow running scripts at varying intervals."

"In Checkmk, the documentation can probably be improved a bit more."

"It is easy for tech-savvy people, but newcomers might find it intimidating."

"The initial setup is a bit complex."

"Sometimes we receive alerts, and it can become annoying when you acknowledge an alert. It is very clunky when you acknowledge the alert. The process is not very intuitive, and there are instances where it feels a bit cumbersome to acknowledge an alert."

More Checkmk cons
