Drill-down monitoring shows us the entire transaction chain, from the front end to back end. It needs HTML5 interface.

I want to see a new interface that contains HTML5 features. The current version of Foglight (on-premise edition) is so fusty in comparison with leaders of Gartner APM Quadrant - i.e. Appdynamics, NewRelic, Dynatrace. If you try to compare SaaS and on-premise Foglight versions you can see differences in UI-design. It's my subjective experiences, but SaaS version looks more modern. Hope this helps

Has enabled us to detect issues instantly through alerts and monitor every service from a single dashboard

Splunk requires significantly more improvements compared to Splunk AppDynamics, specifically regarding the licensing aspect. Splunk renews licenses every six months, which is inconvenient. It would be better to have a one-year license to avoid needing to update keys constantly, which can only occur on weekends, making it a burdensome task. Although Splunk is better for certain use cases, Splunk AppDynamics is broader in functionality. Specifically, I want enhancements related to creating dashboards not only for logs or minor services but also for configuration levels, allowing us to check configurations immediately without manually opening the entire code when exceptions arise—a feature I wish to see improved in Splunk, although it may not be necessary for Splunk AppDynamics.

Cons

"I would perhaps like to see more SSMS connections."

"I think installation and setup needs little more improvement especially when you are installing with external database."

"It needs a more intuitive way to create and implement custom "Cartridges" to be deployed through out a Federated environment."

"The version compatibility needs work."

"Being able to incorporate other bespoke monitoring into Foglight would have made the tool even more useful."

"I want to see a new interface that contains HTML5 features. The current version of Foglight (on-premise edition) is so fusty in comparison with leaders of Gartner APM Quadrant - i.e. Appdynamics, NewRelic, Dynatrace."

More Quest Foglight for APM [EOL] cons

"The main concern is the extensions and their documentation, particularly for the installation of Azure app services. It is lacking some documentation, which is why we are always with the AppDynamics team for support to get the details."

"We have had downtime, which has been the result of config, application, or cord issues."

"There could be some improvement in the constructions of the diagrams, it is too difficult currently."

"The tool is expensive."

"If I consider what can be improved in Splunk AppDynamics, I would point out that it could enhance its reporting capabilities, as it remains very technical."

"The initial setup is a bit complex."

"The solution's user interface should be improved."
