Fusion Reactor has a novel approach to collecting useful information that does not negatively affect real-time performance of our systems. APM tools are no good if we cannot leave them running in production due to fear of slowdowns!

Additionally, the views available are very helpful. There is an overall view to see at a glance any instance which may be having issues, and from there we can dig in to the details to find root cause. Review collected by and hosted on G2.com.

We have only just started using it but have seen nothing to dislike so far. Review collected by and hosted on G2.com.

The sheer amount of data collected and categorized from our servers and applications is amazing. The ability to see the level of detail on threads, headers, stack traces, etc. is very powerful. Add to that, the ability to setup monitors that can queue requests when resources are strained or to live debug an issue on a production server, and you have a very useful tool set.

The cloud options add a higher view level for groups and multiple servers at once. Additional alerting and metrics options are available here as well. We have only started to explore these options, but they look to add value to the overall product.

The Longest and Slow Requests feature is very helpful to our team. We can drill into the details of the request and all of the transaction elements even down to the JDBC request elements.

We initially purchased FusionReactor to help us track down a stubborn heap space issue that was very difficult to recreate in the development environment. FR played a huge role in helping us find the offending code and process. We have since renewed two years in a row, and continue to consider it a valuable tool.

The local Administration Manager is a bit clunky. If you use the manual installation method for the FR files into your server instance, it is more difficult to manually add/register an instance in the manager application for the dashboard view. You also cannot use the manager to upgrade the existing instance if you had originally manually installed the FR product. The documentation about this is a little unclear.

I love the live combined insight into all servers. It's a one stop shop for overall system status Review collected by and hosted on G2.com.

It's harder to diagnose issues in the past. Would like better advice from the app, as to what is causing a recurring issue. Review collected by and hosted on G2.com.

Realtime stats and running requests are vital to track down hard bugs or concurrency issues Review collected by and hosted on G2.com.

Most of all I dislike G2 for soliciting reviews in exchange for an amazon gift card that they then don't provide. I'm sorry fusionreactor partnered with a dishonest company.

I wish it was possible to programmatically enable & disable fusionreactor licenses.

It should also be possible to open WebRequest details or traces in a new tab, but all the links are javascript based, so its not possible. This makes it frustrating to watch running requests and then drill down on individual request details. You can only see on at a time, and when you return to the running transactions page it forgets the "auto refresh" setting. Review collected by and hosted on G2.com.

I like being able to kill processes in the main lists. I can see what requests are hanging in my dinosaur system. Checking out system resources, and the log of longest requests is a great way to keep tabs on your coldfusion environment. Review collected by and hosted on G2.com.

Upgrades are a little tricky, but their customer support team is knowledgeable and helpful to get everything up and running. GRANTED, My version of CF is archaic, I bet it would be way easier for newer installs. Review collected by and hosted on G2.com.

I like being able to see everything that is currently running and quickly identify issues Review collected by and hosted on G2.com.

There isn't anything that I dislike, it is very robust and easy to use Review collected by and hosted on G2.com.

The high level of functionally available as well as the range of tools available. I also like the Cloud version which we have recently upgraded to on Ultimate version. I like the facility to view the SQL statements as well. Price is good value. Review collected by and hosted on G2.com.

With the level of functionality it it not always easy to find the source of the problems and terminology is not always that user freindly. Review collected by and hosted on G2.com.

It's an all-in-one dashboard to monitor the performance of our web application. The breakdown is detailed and it is quick to process. Great user interface, easy to navigate. The convenience of having everything in one place is extremely helpful when working with a ginormous program, and the intuitive design allows for someone new to the company to adapt to it quickly.

I haven't had the chance to explore the application in great detail, so far no complaints. Review collected by and hosted on G2.com.

Cloud installation was a guided step-by-step, well documented convenience and the User Experience did not require me to think too hard about what I was looking for Review collected by and hosted on G2.com.

There is not much to dislike about FusionReactor itself, but I would say it cannot be used as a stand-alone monitoring tool for observability into your production infrastructure. It is a compliment to an existing monitoring service (i.e. New Relic, etc.) Review collected by and hosted on G2.com.

It's easier to monitor servers and application performance with FusionReactor. We can also monitor slow JDBC queries here. It's quite helpful for me as a developer to evaluate our codes and queries performance. Review collected by and hosted on G2.com.

At first, I was a bit unfamiliar with the interface, so I had a little trouble using it at first.

Also, in some cases when the SQL queries are too long, FR often displayed it incompletely. But other than that, it works as expected. Review collected by and hosted on G2.com.
