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…

Performance Test Engineer at TANIM CONSULTING, LLC
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

"It's very easy to manage and monitor it."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"Being open source lets us customize it for our monitoring needs, saving us money."
"It's very easy to manage and monitor it."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It gives me the ability to trace logs between transactions, for example, a DB transaction or JVM transaction from one hub to the other. I can easily find out where the problem is or where the bottleneck of the issues lies."
"The feature that is most valuable to us is the snapshot feature. It allows us to get a snapshot of different SQL scripts that are being executed simultaneously and we can identify everything we need on them."
"The most valuable feature is the ability to take a report, and in particular, a visual, and link it to actual application performance and then the consequences."
"We were able to correct problems, which led to an increase in availability, time savings, and performance for our solutions."
"The metrics browser is very useful, and the deep dive feature is very useful for us."
"I rate Splunk AppDynamics 10 out of 10."
"In my experience, it's easy to use. There's nothing complex to learn or fear. You can quickly adapt to it without the need for extensive training."
"Knowing which tables on the database were working the most was valuable. It helped the client understand where they need to focus. They streamlined a lot of their queries and brought the resource usage down. It helped them to find long-running queries. They rewrote them completely so that they don't take as long and the application performs better."
 

Cons

"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"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."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"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 the transaction naming features, for business transactions, we are not always able to tie a business transaction to a real user transaction."
"To improve Splunk AppDynamics, it should migrate seamlessly into observability Splunk, which is called Splunk Observability Cloud."
"We have had some stability issues for a few sites. At distribution centers, we've had a few issues, but not as a whole."
"I would like to see improvements with respect to the visibility of the network. It currently provides visibility on the application side, but not on the network layer."
"Scalability-wise, I think it's a little limited on an enterprise-wide scale."
"We would like to be able to easily use this solution to monitor our Java script based browsers, which are currently blocked by the security settings."
"The limitations are often due to the vendors not supplying all the profiling features to AppDynamics."
"Sometimes, it can be a little bit too crowded; all the screens."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"The tool is expensive."
"The solution has a high cost."
"AppDynamics Database Monitoring is expensive. I rate it a seven to eight out of ten."
"There is a license for the solution and we paid approximately $2,000. There is also an additional cost above the standard license which cost us approximately $3,000."
"We have a license-based solution. That means you need a license for each server you monitor."
"The license fee for Application Analytics is in the range of 2.5 million over three years, with extra fees for service contingencies."
"I believe there was probably an extra charge whenever I wanted to contact the support team."
"Yearly payments have to be made toward the licensing costs of the solution. The solution has no additional costs apart from the licensing costs."
