Executive SummaryUpdated on Aug 17, 2025

Aternity AppInternals [EOL] and Splunk AppDynamics are competing application performance management products. Splunk AppDynamics seems to have the upper hand with its comprehensive features and robust support options.

Features: Aternity AppInternals [EOL] provides detailed end-user experience monitoring and intuitive analytics along with diagnostic capabilities. It offers efficient transaction traces and real-user monitoring. Splunk AppDynamics offers deep application performance insights with real-time data analysis and seamless integration across various platforms, supports code-level deep dives, and delivers a straightforward dashboard for easy monitoring.

Room for Improvement: Aternity AppInternals [EOL] needs enhancement in dynamic application discovery, better integration for complex environments, and advanced analytics features. Splunk AppDynamics could improve ease of configuration for less technical users, offer more flexible pricing, and refine its alerting system for more granular notifications.

Ease of Deployment and Customer Service: Splunk AppDynamics provides cloud-based deployment with high flexibility and superior customer service. Aternity AppInternals [EOL] offers a simple setup but lacks flexible deployment options and needs to enhance its customer support responsiveness.

Pricing and ROI: Aternity AppInternals [EOL] is price competitive, emphasizing affordability and a solid return on investment. Splunk AppDynamics, although more costly initially, justifies the higher expense with its high-value output, advanced analytics, and strong overall performance, ultimately leading to a compelling ROI.

Gyanesh Rahatekar - PeerSpot reviewer
Application performance management and error resolution improved with data-driven insights
Dynatrace has multiple functions compared to Splunk AppDynamics, so Splunk AppDynamics should add those functions, which are not available as of now. Dynatrace has a universal agent that collects all information related to their CI, and if one CI has multiple languages, then there is no need to instrument multiple agents. However, Splunk AppDynamics requires multiple agents; if I have one server with multiple applications in different languages, then I need to instrument different agents for each application. Splunk AppDynamics should work with Dynatrace with one single universal agent that works with all application languages, eliminating the need for multiple implementations.

Quotes from Members

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

Pros

"As an Administrator, before we bought this AppInternals, I didn't have visibility on why items were slow or why an application was not running. This gives us the ability to see what's going on. The application is load balancing. We can now see if its own server has issues or just one specific server has issues."
"Browsermetrix, which is real-user monitoring via JS injection and linked back to TTW via cookie. It allows us to see the experience of every user hitting our sites and analyze performance by region, browser, etc."
"Transaction Tracing is the most useful. Being able to have the transaction stitched together so we can see where the problem is has proven invaluable."
"The product is very useful to find problems in middleware for the application servers, especially agent instrumentation and management is user friendly."
"The capability of analysing each individual transaction captured to a very low level detail (method call/line of code)."
"We just control on the backend of AppInternals what we want to instrument and what we don't want to instrument."
"Clicks to root cause - fast & easy to diagnose and deep-dive"
"I like it that one can match IPs with the application name."
More Aternity AppInternals [EOL] pros
"This solution is easy to use and very powerful, it is a complete tool for us."
"The alert mechanism in AppDynamics enhances server management tasks by using agents installed on each server."
"It has been stable, scalable and manageable."
"The flow map is very valuable to us. Before we installed APM, we had no idea how our application looked."
"The analytics are great."
"AppDynamics is a good tool that offers excellent out-of-the-box dashboards and application topology."
"The feature that I appreciate in AppDynamics Browser Real-User Monitoring is the intuitive and user-friendly dynamic mapping it creates for workflows."
"We had no issues with scalability. It was very good for us."
More Splunk AppDynamics pros
 

Cons

"It would be great if the solution could offer fixed bundles and more features."
"They should find a way for report generation from TTW to run quicker."
"Deployment and agent patch management is not managed centrally, resulting in a large level of effort to update."
"We'd like to be able to find out performance problems on application class and methods."
"Support for PHP, DB and other applications need to be supported."
"The admin dashboard could be easier as it takes a little bit of time to get used to it."
"I would like for it to have automated updates, the way the product updates itself should be all automated, as opposed to what it is now."
"The recording mechanism for synthetic transactions could be improved as well."
More Aternity AppInternals [EOL] cons
"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."
"We would love to see support for more types of agents in the mainframe world."
"The interface and user experience could be better."
"While it is scalable, it could be better."
"The integration ability of AppDynamics with other performance testing tools is an area with shortcomings where improvements are required."
"The integration with cloud services is still pending with AppDynamics. We would like the product to be serverless."
"It's very complex regarding pricing, setup costs, and licensing of Splunk AppDynamics."
"The end-user experience is not really good because we can't catch all of the transactions. We only can catch the full stack of flow transactions, but I think that this is caused by the technology they use. If they will catch every transaction, it will cause a very big load on the performance of applications. The monitoring of all transactions needs improvement."
More Splunk AppDynamics cons
 

Pricing and Cost Advice

"The licensing model is expensive compared to its competitors, but the service it gives to your business, and the data quality, means that it's worth it."
"The licensing model for v9 is better where it is an individual license per server, while v10 licenses are per JVM/ .NET and server instance. The latter model appears to be the model that other APM vendors are using."
"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."
"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 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."
"The way it is structured in terms of price could be better. You pay for individual modules and that adds on to the cost, which detracts you from implementing those modules and slows you down."
"The price of AppDynamics could be reduced in my region."
"The pricing of the solution is reasonable for what features you receive."
"One of the main downsides to the solution is its cost."
"There is no standard license instead, the license is adapted to the organization's requirements."
