A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

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

"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"It's very easy to manage and monitor it."
"Being open source lets us customize it for our monitoring needs, saving us money."
"It allows us to configure health rules so that we can, based on our own experience, determine when an application is behaving incorrectly."
"The ability to identify the top running queries has been extremely valuable for us."
"What I like most about AppDynamics Server Monitoring is that it's easy to manipulate and easy to implement. All solutions have the same features, but what sets AppDynamics Server Monitoring apart is that it's really quick to implement. AppDynamics Server Monitoring has a great interface. As a developer, it doesn't matter whether it's SolarWinds, Dynatrace, or any APM you're using, but it would matter to the customer. A product must be easy to manipulate or use, for example, AppDynamics Server Monitoring, for the customer, but for developers like my team, there's no pressure, even if a solution requires coding."
"Once you get past installation, AppDynamics is highly stable and we get good results."
"The solution's most valuable feature is the response time from the end-to-end server."
"You have a live view of what happens when something goes wrong on the production or support side. You don't have to scramble and do guesswork. We can identify the query that creates the bottleneck or slows the performance of the database system. It can give you points on how to debug and fix the system."
"We have found the scalability to be quite good."
"One noteworthy feature is user journey analysis, which enables tracking user interactions and conversion paths on a website."
 

Cons

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"Sadly, I did not see return on investment with Splunk AppDynamics."
"It's very complex regarding pricing, setup costs, and licensing of Splunk AppDynamics."
"It would help to maybe have a more graphical interface and more user-friendly graphics."
"The overall performance of this solution could be improved. The hot-hot infrastructure features could also be improved."
"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."
"Things are being done differently in the industry now, and many of these problems are being solved with cloud databases."
"The integration with cloud services is still pending with AppDynamics. We would like the product to be serverless."
"There needs to be an option to capture all the sessions for all the users, not just samplings."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"AppDynamics is one of the most expensive solutions on the market."
"As compared to other applications, its price is moderate. Its price is neither very high nor very low."
"The cost is prohibitive."
"It would be better if there were more solutions incorporated into the base price. ​"
"AppDynamics does not usually do monthly payments. They do it on an annual basis, at the very least."
"I believe there was probably an extra charge whenever I wanted to contact the support 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 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."
