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

"Capacity on database and file servers. I found the algorithms to forecast growth and concerns particularly intuitive."

"Excellent monitoring capability and business service views"

"Having standard monitoring features and a central repository saves us a lot of time and reduces risk of incidents."

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

"The ability to track performance of an application or application suite over time is extremely valuable to our business partners and for our application development team with near real time results."

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

"The most valuable feature is drill-down monitoring, which shows us from one interface the transaction chain from the front end to back end."

"The extensive monitoring tools embedded in Foglight are a real asset."

More Quest Foglight for APM [EOL] pros

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

"I feel AppDynamics is really unique, because I really want to check our loss."

"With Dynatrace, AppDynamics Mobile Real-User Monitoring is one of the best tools on the market."

"The most valuable feature of AppDynamics is its ability to track the transactions between different applications."

"I would really say if you are an enterprise company, then AppDynamics is the product of choice, but if you are a small company, just starting a business and you need a solution that is quick and easy to install and gets up to speed very quickly, then DataDoc is an alternative."

"This practice has transitioned our testers to engineers."

"The solution is very scalable, and you can get the performance data from the end users, so it provides a proper way to analyze data from different regions."

"Once you use AppDynamics it feels like you were standing in the dark before."

More Splunk AppDynamics pros

Cons

"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."

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

"I recall that the lay-out was rather dull when I used this particular version of Foglight."

"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 current version of Foglight (on-premise edition) is so fusty in comparison with leaders of Gartner APM Quadrant - i.e. Appdynamics, NewRelic, Dynatrace."

"They need to improve the stability of FxM and FxV."

"The upgrade process could use some fine tuning. I have done an upgrade of the system as well as addedupdated agents, and sometimes that process is a bit cumbersome, and does not go as planned."

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

More Quest Foglight for APM [EOL] cons

"The network diagnostics that they are adding will be really useful. They could add more detail into what is going on in the network."

"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."

"For me, the single largest area with room for improvement that I've been requesting the AppDynamics team to deliver for us is APM support for Ruby on Rails and for HHPM."

"They are using Flash for their website, which is very slow. We had hoped the website would be much faster to use, and that is definitely what we want to see."

"I would say that the support is 50/50. It is not very fast and there is definitely room for improvement in terms of support."

"We miss more information for tweaks at the OS level and resource usage."

"The limitations are often due to the vendors not supplying all the profiling features to AppDynamics."

"This product has an issue with initial lag upon opening that we would like to see improved."

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."

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

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

"We buy the platform's yearly subscription."

"The pricing model for AppDynamics could be better. You have to subscribe to a yearly or a three-year licensing, which isn't very handy. The solution is one of the most expensive in the market today."

"I would like more flexible pricing: A pay-per-use model, rather than just a fixed-price model."

"I rate AppDynamics Mobile Real-User Monitoring's pricing as seven out of ten. Mobile monitoring is paid based on the number of instances utilizing the mobile monitoring service, which increases as the scale grows. Consequently, your mobile user count can proportionally surpass all other applications."

"I give the price a five out of ten."

"The pricing is quite comparable to similar solutions in the market. All these solutions at the moment are cheap, but it is like paying for insurance; you pay insurance to avoid major damage."

"I was not involved with the procurement of AppDynamic, but I believe it's expensive."

"The licensing cost is fairly high"
