Featured Reviews

Harrison Bulley - PeerSpot reviewer
Senior Infrastructure Engineer at Net Consulting
A stable, scalable and cost-effective solution that helps with inbuilt scripts for easy modification
I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built.
Shamim Alsharif - PeerSpot reviewer
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

"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."
"The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated."
"Icinga2 was designed to delegate, distribute and balance tasks between several nodes."
"People should know that it is simple and advanced."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"The most valuable feature is one that not many are even aware of, as Icinga has a self-healing event handler where if the service is down, it is automatically restarted, and you can configure the handler to take action after the critical alarm without human interaction."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"You save time by using this solution allowing you to utilize that saved time towards developing new features for your customers versus trying to troubleshoot the ones that are not working properly."
"Autodiscovery of application topology, based on real user traffic."
"Using AppDynamics, we have been able to monitor what is happening using fantastic metrics that it provides."
"I've been really happy with it and everything we want it to do, it's done."
"We switched to AppDynamics for its capabilities."
"I have seen a return on investment with Splunk AppDynamics, as we are investing more and more for Splunk AppDynamics because we have many tools and many applications in our organization."
"Technical support is great."
"The most valuable feature is having our services being available and healthy."
 

Cons

"The user interface should be improved."
"Network Discovery capabilities would be extremely helpful."
"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."
"Icinga is a complex solution that's hard to learn. It's a powerful product for monitoring, but new users will have a hard time figuring out what to do."
"Sometimes, it is very hard to keep an overview of what's happening."
"One of the areas that are frustrating is remote monitoring for more than one machine."
"The only reason I take off one point is the cost. I can't give it a ten because it is not a cheap product."
"It could be integrated with more performance-testing tools for more intensive use."
"The only improvement I see is intercepting calls in a mobile application without injecting additional code. Currently, when instrumenting or monitoring a mobile application, it's necessary to release updates, prompt users to upgrade, and inject code into the backend. It would be beneficial if there were a method to intercept these calls without requiring users to download and upgrade the application. However, I'm unsure about the feasibility of such an approach."
"Scalability-wise, I think it's a little limited on an enterprise-wide scale."
"The AppDynamics installation process needs to be more straightforward. Deploying the product is also tricky."
"I wouldn't say I am 100% satisfied. There have been times that it fails."
"One of the things that we would like to improve a little more is the dashboards. The dashboards are good, but I believe that they could improve even more."
"AppDynamics is dealing with a lot of products and technologies, so we need to have clear documentation."
 

Pricing and Cost Advice

"This is an open-source solution with paid support."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"It's an open-source solution."
"The product is inexpensive compared to other DBM products."
"We're using the free version of Icinga."
"The solution is cheap."
"The solution is free to use."
"Pricing is based on the size of the deployment."
"The price of AppDynamics could be reduced in my region."
"AppDynamics does not usually do monthly payments. They do it on an annual basis, at the very least."
"Because it is priced per JVM, the price can increase pretty fast, into the millions. We have had challenges because we had to justify the price to our clients, as well, when we are putting in certain tools."
"There is no standard license instead, the license is adapted to the organization's requirements."
"AppDynamics Server Monitoring is a very expensive product, but if you negotiate well, you get value for money...My company used to make early payments toward the licensing costs of the solution, but now my company has opted for a different licensing model."
"If one is expensive and ten is low price, I rate the product price as seven out of ten."
"It is a more expensive APM among the competitors, which is fine because it also does a lot more on the auto-detection and the AI side... It is not a cheap product. None of them are. The price is fair, but I could use it on more projects if they had a lower price."
