SI
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…
Muhammad Zeeshan Siddiqui - PeerSpot reviewer
Dynamic mapping enhances workflows that are user-friendly
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. If AppDynamics could develop a means to monitor without an agent, it could significantly improve application performance and reduce potential problems. Moving to an agentless solution, like what some competitors are doing, would be beneficial.

Quotes from Members

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

Pros

"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 is easier for client installation, and the configurations are doable even for a newcomer in the field."
"It has been stable, scalable and manageable."
"The auto-discovery of the logs is the most valuable feature. It requires minimal configuration, we just need to set up on once and it automatically detects through the code."
"AppDynamics has been stable."
"The most valuable feature of AppDynamics is Proactive Monitoring and Alerting."
"The most valuable feature is the detailed statistics, like the consumer count, for the ActiveMQ server."
"The most valuable aspect of the solution is the ability to discover and track transactions."
"Capacity planning is, in my opinion, the most useful."
"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."
 

Cons

"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."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"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."
"Improvements can be made in the area of AI integration."
"The training on the dashboards that is provided could be a little bit better, as could the use cases. They should have some good examples out there. As it is right now, I had to scour YouTube to find some stuff."
"The synthetic scripting for end-user monitoring could be a little bit broader. Instead of using just Python, they can include a few other languages so that not everyone has to jump on the bandwagon for Python and do Selenium scripting. They can open up that a bit to make it simpler for people to do the scripting."
"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."
"The integration with cloud services is still pending with AppDynamics. We would like the product to be serverless."
"An improvement could be if the monitoring was able to be summarized into something more clear and simple for people who don't have the technical skills on the database side."
"They do not have robust documentation."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"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 license for AppDynamics is procured by our customers."
"AppDynamics is an expensive solution."
"I would like more flexible pricing: A pay-per-use model, rather than just a fixed-price model."
"It's a very expensive product. Each of the licenses after this month for one server is around $9,000 or $10,000."
"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."
"AppDynamics is really pricey as it requires licenses for every feature."
"The pricing needs to come down."
