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…

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 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."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It's very easy to manage and monitor it."
"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."
"AppDynamics has become the go-to tool for issue identification."
"Because of AppDynamics, we came to know where the bottlenecks are in the infrastructure by using the system agent, as well as the JVM agent."
"Error analysis in the troubleshooting sections go straight to the point."
"APM tool provides comprehensive information about several elements like performance, errors, and resources."
"It works great for doing what you need, when you want to track response times and error rates; and especially being able to dig down to individual transactions and see the actual call methods."
"This product has improved the performance management of our applications before deploying them to the end user."
"Overall, it is a very strong product, with most of the features that we need, and other than some usability improvements, I think it is a very great product."
"We can see the customer's path from their computer to the backend systems."
 

Cons

"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"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."
"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."
"Regarding Search Guard functionality, there is room for improvement."
"If we consider the implementation of alternative solutions, such as Dynatrace, there is a notable difference in the approach to agent-based service monitoring. For instance, Dynatrace employs a single-agent solution, which can pose security concerns. When installing Dynatrace, granting the agent ld pro payload rights is a requirement. In contrast, our solution ensures a more secure approach by not requiring root and administration access. While we currently utilize an agent-based solution, there may be a shift in the next one or two years, possibly with the adoption of Open Telemetry. It's anticipated that many APM vendors, including Dynatrace, may alter their structure or strategy for implementation. However, as of now, the trend is towards an increasing number of implementations daily."
"The networking monitor function could be better, we are not getting many details from it."
"This product has an issue with initial lag upon opening that we would like to see improved."
"It would help to maybe have a more graphical interface and more user-friendly graphics."
"AppDynamics Database Monitoring could improve the price of the solution, it is costly."
"The end-user experience is not really good because we can't catch all of the transactions."
"Things are being done differently in the industry now, and many of these problems are being solved with cloud databases."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"Yearly payments have to be made toward the licensing costs of the solution. The solution has no additional costs apart from the licensing costs."
"You are required to purchase licenses whether you use it or not. It is not pay-as-you-use."
"The pricing of the solution is reasonable for what features you receive."
"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."
"We have purchased a few licenses for AppDynamics Database Monitoring and the price is high."
"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."
"The pricing is very competitive."
"I give the price a five out of ten."
