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.

Quotes from Members

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

Pros

"It provides a history of the activities on our SQL servers."
"At a glance I can easily see what is going on with all of my VMware ​environments, including top consumers of resources."
"Infrastructure Monitoring and End User Monitoring are the product’s most valuable features to me."
"With the APM you can replay the end user session and see issues quickly by viewing the session."
"Capacity on database and file servers. I found the algorithms to forecast growth and concerns particularly intuitive."
"FxV is valuable as we can playback the session."
"The most valuable feature is drill-down monitoring, which shows us from one interface the transaction chain from the front end to back end."
"Dell Foglight does analyze and optimize your virtual infrastructure. It definitely reduces operational cost."
More Quest Foglight for APM [EOL] pros
"What I like the most about Splunk AppDynamics is the end-to-end observability for the application, along with traces."
"That visual representation’s been really good, also the overhead that AppDynamics creates is quite small. We've tried Dynatrace in the past. Some of the applications didn't work as well with Dynatrace."
"I like that AppDynamics allows every organization to have what they want to see, like for my organization, we're able to customize the dashboard to show us details of what we want to see in our transactions."
"The features related to the application performance in AppDynamics Database Monitoring are the most valuable."
"Once you get past installation, AppDynamics is highly stable and we get good results."
"We had no issues with scalability. It was very good for us."
"Application Analytics' most valuable features are the real-user monitoring and the agents installed in the software stack on the application server."
"What I found valuable in AppDynamics Database Monitoring is good technical support. I also like that it's scalable and stable."
More Splunk AppDynamics pros
 

Cons

"I would perhaps like to see more SSMS connections."
"My only complaint from Foglight for monitoring is that you only get a plot for five minute average for metrics like CPU and Memory, on the application side I can see metrics more quickly at 15 seconds for metrics like active sessions, heap. I would like to see the same for CPU and memory."
"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 mobile access application in the next release."
"I think installation and setup needs little more improvement especially when you are installing with external database."
"They need to improve the stability of FxM and FxV."
"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."
"It needs a more intuitive way to create and implement custom "Cartridges" to be deployed through out a Federated environment."
More Quest Foglight for APM [EOL] cons
"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 integration part in AppDynamics with other systems is an area with a little difficulty, especially when it comes to the configuration area. The integration of AppDynamics with other products takes a lot of time."
"I would like to see some cosmetic enhancements."
"The downside is that it's a little costly."
"The solution's user interface should be improved."
"This feature needs to be properly described to a client, and then the client needs to have a use case. There are some clients which do not need it and some clients who do. It is not for everyone and is dependant on their use case."
"An area for improvement in AppDynamics Server Monitoring is integration; in particular, it needs a better way to integrate with custom applications such as Siebel CRM. Right now, it's challenging to integrate AppDynamics Server Monitoring with Siebel CRM because it sometimes gives an error and cannot integrate properly."
"The solution could improve by covering more technologies. For example, it does support .NET Core applications. However, it could be a bit better."
More Splunk AppDynamics cons
 

Pricing and Cost Advice

"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."
"Since the product split – the licensing is a bit more complex."
"The price is expensive for us."
"For those who appreciate the value and had issues with the visibility of the performance of their applications, then the pricing is good. For somebody who does not need it, it can be pricey, but overall, it is worth the money which it costs."
"There is a license to use this solution. However, the clients pay for the licenses we are the service provider."
"It's a very expensive product. Each of the licenses after this month for one server is around $9,000 or $10,000."
"AppDynamics Server Monitoring is an expensive solution."
"We buy the platform's yearly subscription."
"Yearly payments have to be made toward the licensing costs of the solution. The solution has no additional costs apart from the licensing costs."
"AppDynamics is one of the most expensive solutions on the market."
"We are looking forward to purchasing the solution on the AWS Marketplace."
