Great for visibility but lacks many features and difficult to update

We're customers. We don't have a special relationship with the company. I am the operation's application administrator. At the moment, the solution is monitoring the applications that we want it to monitor. We're not looking at it on a daily basis. We just use it here and there. The challenge we have is that we believe that Dynatrace can address some tasks we'd like done that are not possible to execute on this solution. Dynatrace includes monitoring of not just the logs, but the applications as well. Dynatrace also makes us include firewalls, etc. We could have it so there are end to end solutions or identifications within the process. What we have right now is only the app server as well as the database server and its connectivity. The solution does save time that's caused when creating SQL coding. However, there are some issues around AppInternals changing the code and giving us issues. From the point of view of the top management, we want a more permanent solution. We want to identify what causes issues and we are looking for a more end-to-end solution. That is why we are looking at Dynatrace. I don't know if I have any advice for other organizations. The experience I have is only based on my own limited experience. However, I believe that the application has the potential to be really good if it identifies what is really important to an organization. It's still sort of half-baked without AppResponse. Without the other key features in infrastructure, like the network, firewalls, and proxies, it's lacking. It's not fully complete. I'd rate the solution six out of ten. It addresses some of our needs, but there's a lot lacking that could be added to make it a fuller, more interesting product.

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

"If you want to save time for problem resolution, and to address problem on your environments you should try Riverbed OPNET."

"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."

"I like it that one can match IPs with the application name."

"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, and this gives us the ability to see what's going on."

"The product is very useful to find problems in middleware for the application servers, especially agent instrumentation and management is user friendly."

"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."

"The most valuable aspect of this solution is the integration with their other systems. It's easy to understand and it points out the relevant problems in the enterprise."

"The most valuable aspect of this solution is the integration with their other systems, it's easy to understand and it points out the relevant problems in the enterprise."

More Aternity AppInternals [EOL] pros

"AppDynamics is a good product and I totally recommend it."

"We just started using it so it is a little too early to tell but we have already seen how APM finds the issues with the different applications, which is very important for us."

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

"This is purely an application instrumentation and monitoring tool with good features for business analytics."

"This is a stable product and we definitely plan to continue using it in the future."

"Application Analytics' most valuable features are the real-user monitoring and the agents installed in the software stack on the application server."

"Quicker turnaround on finding/resolving issues or improving performance, which leads to improved client experiences."

"This solution not only provides answers but also provides sensor data. This allows us to quickly resolve issues that developers may take a long time to solve."

More Splunk AppDynamics pros

Cons

"The technical support is not very good and should be improved."

"They should find a way for report generation from TTW to run quicker."

"The recording mechanism for synthetic transactions could be improved as well."

"It's not as good as it was three years ago before meddling by an activist investor, privatization, and subsequent layoffs hurt support."

"It would be great if the solution could offer fixed bundles and more features."

"It wasn't a critical issue, but it was hot enough to where it would have been nice to get some guidance from Riverbed, but they went ahead and let us down, but that was only one occasion."

"Deployment and agent patch management is not managed centrally, resulting in a large level of effort to update."

"We have put in a request as an enhancement that we would like to search for items. If we're searching for a URL and we want to know was it a get or was it a post."

More Aternity AppInternals [EOL] cons

"I see that the main challenge with Splunk AppDynamics is the management of multiple agents, as installing several agents on a server is a significant hurdle we still face."

"The integration with cloud services is still pending with AppDynamics. We would like the product to be serverless."

"There may be some older technologies that are still covered, however, it's not as plug-and-play."

"This solution is expensive."

"It could be more user-friendly for beginners."

"Sometimes, it can be a little bit too crowded; all the screens."

"Scalability-wise, I think it's a little limited on an enterprise-wide scale."

"An area that has room for improvement on the CR and ERP would be the addition of monitoring of the internal solution. For example, you can monitor the day-to-day and everything in the transactions with AppDynamics, but there's also a lot going on in the kernel itself that you cannot monitor. The automation needs to improve as well. As it stands, a lot of customization needs to happen before you can use AppDynamics."

More Splunk AppDynamics cons

Pricing and Cost Advice

"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."

"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 price of AppDynamics could be reduced in my region."

"The solution is highly expensive"

"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."

"It could be a bit lower, but looking at the scalability, functionality, and other things, you can understand why AppDynamics is so expensive as compared to some of the cheaper products that don't have that full single pane of glass they've got. Dynatrace has got three different elements that you need to log into just to get a full view, which is not so good, and because of that, it is a bit cheaper."

"AppDynamics Database Monitoring is expensive. I rate it a seven to eight out of ten."

"The license fee for Application Analytics is in the range of 2.5 million over three years, with extra fees for service contingencies."

"One of the main downsides to the solution is its cost."

"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."
