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

"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."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"This solution gives us quite good insights that we might otherwise overlook, or it might take a really long time to debug those issues."
"The features that I like best are the dashboard and Business Journey."
"In the case of a mobile banking application, AppDynamics Mobile Real-User Monitoring successfully reduced the response time from eight seconds to just one second. In another example, the tool identified an issue within the mobile app, causing lost transactions in the billing system."
"It is easy to gain visibility into complex environments with AppDynamics. It has the ability to combine operation information of the environment and business information with strong business IQ support."
"The business transaction that stands between multiple applications is proving to be most valuable."
"The proactive monitoring from AppDynamics definitely helps."
"It has improved our organization with its ability to catch issues quickly and fix them."
"The solution's most valuable features are its end-user monitoring and AI functionalities."
 

Cons

"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"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."
"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."
"We have had downtime, which has been the result of config, application, or cord issues."
"Rolling out version upgrades is a difficult job at times."
"AppDynamics lacks integration with cloud technology. It probably isn't a good fit for emerging enterprises because it's an on-premise solution, and many newer companies are moving to the cloud. AppDynamics' on-premise technology works reasonably well, but it doesn't have cloud features."
"At this time, we don't have much visibility on the virtual environment, monitoring, and all other things. We have visibility only for database monitoring, and we have noticed performance impact when deploying database agents on the database server. We got to know this from AppDynamics support also that we should not deploy database agents from the database server. When agents are deployed on the same server and the database is monitored from there, we are not getting database server metrics. Therefore, we don't have those insights, and sometimes, we struggle because of that. They can improve this functionality so that we do not have a performance impact, and we can deploy anywhere. This would help us a lot. In terms of end-user monitoring, currently, it is not working for us because there are some complexities. It is a little complicated, and it takes a little bit of time to understand where you need to make changes. It would be very helpful if they can provide some template designs for end-user monitoring. When our servers are running on VMs, we don't get many insights from the VM side. I don't know whether it is possible to have visibility beyond the database, server, and application and whether there are some features where we can deploy AppDynamics on VMs as well. Such functionality would give us more control over storage, VM, OS, and database. It will also provide complete visibility of our hardware and software."
"The price of the solution could improve."
"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 tool is expensive."
"I would like to see accommodation for millisecond granularity, as we only have one-second granularity now."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"AppDynamics Browser Real-User Monitoring does have licensing cost associated with it."
"There is an annual cost to use this solution. The licensing model could be improved by making it more cost-effective."
"Pricing is based on the size of the deployment."
"You are required to purchase licenses whether you use it or not. It is not pay-as-you-use."
"AppDynamics offers a yearly basis license."
"The licensing cost is fairly high"
"As compared to other applications, its price is moderate. Its price is neither very high nor very low."
"The product’s licencing policy is competitive. However, properly identify and size your needs to get the best rate."
