I wouldn't want the interface to go towards the web because they did have a version that was inside of the TruView product. It was more web-based and, to me, the web-based applications lose the robustness of the intimacy of a true character interface. I liked that they were on that path and I hope that they stay on that path because it just looks like it's a better product. I would like to see a multi-user version where you can have a launch platform and, potentially, instead of buying six licenses you buy 12 seats or something like that. From a centralized platform, you could have multiple users using that particular product in a series of different ways. That's what I'd like to see, rather than having everybody running a standalone one on their own workstation.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Quotes from Members

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

Pros

"What ClearSight will do is it actually maps out the conversation for you."
"This is the best protocol analyzer I've used and I've used some from WildPackets and quite a few other places."
"The dashboard allows you to see what's going on in the overall system."
"The alerting system is very effective."
"I can monitor a software made in-house to software of bigger companies."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"Nagios is the best monitoring tool that I have ever worked on."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"Nagios XI is stable."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
 

Cons

"I would like to see a multi-user version where you can have a launch platform and, potentially, instead of buying six licenses you buy 12 seats or something like that."
"I was upset when they sold the product to NETSCOUT."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"I would like to see support for notification via SMS."
"However, it is a bit complex and difficult for a first-time user."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"Nagios provides most of the features by default, however to add more services to it, it requires additional plugins which require little effort on administrative end."
"I would like to see more customization in the network map because it is a bit tricky to use it."
 

Pricing and Cost Advice

"It was pretty modest because you could get it in different ways. I think the six licenses, at that time, were about $1,000 each. But then again, I work for a school and educators tend to get discounts on things. So maybe it cost us about five or six hundred a copy."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Licensing costs are reasonable."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"The licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
