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.

Quotes from Members

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

Pros

"FxV is valuable as we can playback the session."

"Real time database monitoring and alerting are valuable."

"With the APM you can replay the end user session and see issues quickly by viewing the session."

"It was easy and saved costs."

"A lot of features for the price: Java/.Net instrumentation, End User replay (similar to TeaLeaf), and a huge library of monitoring cartridges."

"Dell Foglight does analyze and optimize your virtual infrastructure. It definitely reduces operational cost."

"We are able to capture the real time user experience of our solutions and we have an understanding of overall performance."

"Our ROI has been great it has saved us many times to resolve issues before customers started complaining."

More Quest Foglight for APM [EOL] pros

"AppDynamics allows users a complete application monitoring solution for making better products and applications."

"The initial setup is simple."

"The most valuable feature is giving end-to-end, about the business transactions, specifically, which is an area everybody struggles with."

"The good part with AppDynamics is that you get all three layers, even though there still are some missing links."

"There are so many tools in the market, depending upon the criteria and what you want, I would definitely suggest AppDynamics, because of the REST things and all of that."

"AppDynamics Browser Real-User Monitoring provides smooth connectivity to different applications."

"It provides great tools for monitoring and managing all the different environments of Dev, QA, and Prod with different needs but from a common interface."

Cons

"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."

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

"In an older version of Foglight, we were not able to get any of our custom agents to work properly so that feature was not as much use as we had initially hoped and haven't tried using since."

"The “cartridge” concept for every little thing is a bit of a bother to implement."

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

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

"The “cartridge” concept for every little thing is a bit of a bother to implement."

More Quest Foglight for APM [EOL] cons

"The synthetic scripting for end-user monitoring could be a little bit broader. Instead of using just Python, they can include a few other languages so that not everyone has to jump on the bandwagon for Python and do Selenium scripting. They can open up that a bit to make it simpler for people to do the scripting."

"There are too many installers available for this solution."

"Actually, it still takes some time when I want to find some requests in time ranges. It's a little slow."

"The tool is a little complicated. I think the UI should be more friendly."

"AppDynamics' modules and hardware resources are very high."

"The downside is that it's a little costly."

"One aspect that requires improvement is the agent. Without an agent, gathering sufficient information on applications is challenging. Additionally, the agent sometimes creates performance issues in production environments."

"I would like to see more artificial intelligence and machine learning brought in to monitor the statement and payment sum issues we have."

More Splunk AppDynamics cons

Pricing and Cost Advice

"The price is expensive for us."

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

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

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

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

"Yearly payments have to be made toward the licensing costs of the solution. The solution has no additional costs apart from the licensing costs."

"We have a license-based solution. That means you need a license for each server you monitor."

"We find its pricing reasonable and competitive. After it was acquired by Cisco, we found it acceptable."

"It does require licensing to be paid."

"This price of this product is expensive."

"We do not have any issues with the price."

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