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

Real-time monitoring has improved our banking API performance and supports detailed business transaction analysis

The real-time monitoring is what we can see for anything that is needed in terms of CPU, memory, or the connections or the sessions related. It's real-time monitoring of performance of each of the components, which is what we need and use all the time. It's highly effective, I would say. Infrastructure visibility, transaction monitoring, to check the actual user experience in terms of the response time, MRT and all those things. We do the component monitoring like the API performance and the connections and all those things, but we also do the business process monitoring and business transaction monitoring.

More Quest Foglight for APM [EOL] pros

"The features, ease of use, and customer service provided by AppDynamics was what tipped the scale towards them."

"AppDynamics makes it much easier for us to detect problems or issues before they become problems, and we have alerting on all of our business transactions, which makes it very easy for us to keep our applications stable."

"Application Analytics' most valuable features are the real-user monitoring and the agents installed in the software stack on the application server."

"AppDynamics does exactly what I want it to do."

"The real-time monitoring is what we can see for anything that is needed in terms of CPU, memory, or the connections or the sessions related, and it's highly effective because we use it all the time to monitor both component performance and business transactions to check the actual user experience in terms of response time."

More Splunk AppDynamics pros

Cons

"South African skill is scarce"

"We had issues with deployment in the beginning until we had an expert guide us through the process."

"SQL agents often failed but again this may have been addressed in future versions."

"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."

"I want to see a new interface that contains HTML5 features."

"The price is expensive for us."

"We have not realized a good ROI on the product due to the fact that we were not able to monitor our core application which runs on Webmethods."

"We are running a Webmethods stack (Software AG) and Foglight is unable to instrument. We are in a POC with Dynatrace and it was able to instrument with little effort."

More Quest Foglight for APM [EOL] cons

"My impression of the scalability of the solution is that it is not very scalable. They are not the market leader anymore."

"One thing that can be improved is the license structure."

"There needs to be an option to capture all the sessions for all the users, not just samplings."

"AppDynamics scaled well up to around 3,000 agents. The performance deteriorated after that, while Dynatrace could support more than 10,000 agents. We were surprised that AppDynamics' scalability is not so good."

"They need to improve the consolidation of agents for the agent's installation process."

"The solution has performance issues after we deploy the agent."

"They should combine the cloud and EPM on-premises together and provide a unified single pane of glass for all their modules because they currently have different modules for infrastructure monitoring."

"Analytics SQL statement monitoring"

More Splunk AppDynamics cons

Pricing and Cost Advice

"The price is expensive for us."

"Since the product split – the licensing is a bit more complex."

"I recall it being a very expensive solution relative to function and stability."

"Foglight can be expensive I would go with the pricing at a three year deal."

"AppDynamics is what I would consider an enterprise-level solution. This means that it's a solution that is intended for use by larger organizations, while small or medium-sized businesses may find it difficult to afford. The number of agents required will also impact the pricing, and smaller companies may only be able to afford a limited number of agents. Essentially, the cost of the solution is not within the reach of every organization, and only some may be able to afford it."

"We have purchased a few licenses for AppDynamics Database Monitoring and the price is high."

"As compared to other applications, its price is moderate. Its price is neither very high nor very low."

"There is a license to use this solution. However, the clients pay for the licenses we are the service provider."

"AppDynamics is an expensive solution."

"One of the main downsides to the solution is its cost."

"Purchasing the product through the AWS Marketplace was good."

"The solution has a high cost."
