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

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

"This level of viewable monitoring had many benefits such as alerting, scalability, reporting and service dashboard we could promote."

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

"Foglight is an awesome tool and it is able to instrument and integrate easily with any monitoring tool."

"At a glance I can easily see what is going on with all of my VMware environments, including top consumers of resources."

"Intuitive, Single-pane-of-glass dashboards for real-time statistics and long-term statistics for capacity management and in-depth analytics"

"The product has improved the way we respond to database issues as it has made us more proactive."

More Quest Foglight for APM [EOL] pros

"The business transaction tier of management is the most valuable feature; the fact that we can go into multiple tiers and monitor the transactions from the end-user point of view."

"We can see the customer's path from their computer to the backend systems."

"It’s great that APM monitors in real-time, and when we have an issue, we find out fairly quickly if there's a problem with our hardware."

"The most valuable feature is that we can see how our end-users are interacting with our application across regions."

"We have more than 100-plus applications being monitored using Splunk AppDynamics, and for application performance monitoring, the product features are really good."

"We can make custom alerts in our system for specific issues like high CPU utilization or application downtime."

"It helped to find quick solutions for specific business transactions."

More Splunk AppDynamics pros

Cons

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

"The price is expensive for us."

"We had stability issues for FTR. The player used to get hung while running the robot scripts."

"There are some metrics I'd like to track that are difficult to find or implement into a tracking solution without a lot of manual work."

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

"I want to see mobile access application in the next release."

"When we first turned on Foglight for the first time, it was like a fire hose."

More Quest Foglight for APM [EOL] cons

"It could be cheaper. It's a little cost prohibitive."

"AppDynamics should improve its ability to track all the transactions."

"It's difficult to install. AppDynamics uses multiple agents."

"The tool is expensive."

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

"I haven’t rated it higher because of the comparison between AppDynamics and Dynatrace."

"The big feature that I would love to see is the ability to extract all the data automatically into some type of a data repository, big data lake, or something where we can do even deeper analysis of the data that AppDynamics gives us."

"The documentation and training material have room for improvement."

More Splunk AppDynamics cons

Pricing and Cost Advice

"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."

"The price is expensive for us."

"I believe there was probably an extra charge whenever I wanted to contact the support team."

"It is a more expensive APM among the competitors, which is fine because it also does a lot more on the auto-detection and the AI side... It is not a cheap product. None of them are. The price is fair, but I could use it on more projects if they had a lower price."

"It is not a cheap tool, but you also save in manpower to setup because it is easy and fast. At the end of the day, I think the revenue is much better. BUT, they have an awful co-term mode of licensing."

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

"AppDynamics Server Monitoring is a very expensive product, but if you negotiate well, you get value for money...My company used to make early payments toward the licensing costs of the solution, but now my company has opted for a different licensing model."

"AppDynamics Database Monitoring requires a license for database monitoring and other features, while Dynatrace provides monitoring and other features out of the box without additional costs. Sometimes this makes it more challenging to pitch AppDynamics Database Monitoring to customers, especially because you need to buy a separate license. As an implementer, I have yet to learn about the pricing for AppDynamics Database Monitoring. Pricing is taken care of by the sales team."

"Take into consideration what you get for specific pricing models and how much it costs to add on things you may need later."

"It is expensive. However, our time to recover has been reduced, and this product has helped recuperate costs and provided us with ROI."
