Featured Reviews

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…
Gyanesh Rahatekar - PeerSpot reviewer
Application performance management and error resolution improved with data-driven insights
Dynatrace has multiple functions compared to Splunk AppDynamics, so Splunk AppDynamics should add those functions, which are not available as of now. Dynatrace has a universal agent that collects all information related to their CI, and if one CI has multiple languages, then there is no need to instrument multiple agents. However, 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. Splunk AppDynamics should work with Dynatrace with one single universal agent that works with all application languages, eliminating the need for multiple implementations.

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 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."
"All the metrics are baselines in networks, infrastructure, application, and user experience. AppDynamics offers its own query language. It is called ADQL. You can write code of any kind to do queries and analysis and you can use those within the reporting or within other research."
"The ability to check parameters for microservice applications is most valuable. It is important for me. I can manually create new business transactions for applications and individually monitor business transactions. I can also use a lot of extensions. It has a lot of extensions to monitor other third-party applications, such as NoSQL applications, memory cache applications, Kafka applications, and Couchbase applications. It is very useful. We are also using the end-user monitoring site to follow all end-user activities. It is important for us to check the errors on the customer site."
"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."
"AppDynamics has been stable."
"It's good for a larger scale deployment such as what my company is working on."
"The product is easy to install, it took about half an hour. The use and the configurations are simple as well."
"Provides good overall application performance and transaction errors."
"Users can configure business sections in their environment, and it's possible for customers to configure different sources for the name of the class, the name of the method, or the name of the web service, which is very interesting."
 

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."
"Installation and configuration can be very tough. An average user without specialized knowledge can't do this. You need to have DevOps and QA teams handle it. During installation, a lot of customers get stuck trying to track the database or the API part, and they have to contact customer support."
"Application Analytics' performance in pure and native cloud environments could be improved."
"In the next release, I would like to see the configuration of the data and more support for new applications. It should support new languages."
"This product has an issue with initial lag upon opening that we would like to see improved."
"One aspect that requires improvement is the agent. Without an agent, gathering sufficient information on applications is challenging."
"Splunk AppDynamics provides an end-to-end view of the application but misses the infrastructure part, which is crucial."
"The setup, implementation and use are clumsy and need to be refined."
"The integration ability of AppDynamics with other performance testing tools is an area with shortcomings where improvements are required."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"AppDynamics Database Monitoring is expensive. I rate it a seven to eight out of ten."
"Yearly payments have to be made toward the licensing costs of the solution. The solution has no additional costs apart from the licensing costs."
"Take into consideration what you get for specific pricing models and how much it costs to add on things you may need later.​"
"You are required to purchase licenses whether you use it or not. It is not pay-as-you-use."
"We are looking forward to purchasing the solution on the AWS Marketplace."
"The licensing cost is fairly high"
"The tool is expensive."
"The pricing needs to come down."
