The setup is straightforward, but the satellite service installation file could be separated from the server one.

* The status overview page provides a state of computers monitored and provides quickly what users need to focus on * The satellite service installed on remote computers is an easy way to add clients, plus it's easy to deploy and to configure * The licence is perpetual and not linked to one computer, so it's possible to remove a licence from one computer and use it on another with no extra cost

Quotes from Members

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

Pros

"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."

"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."

"Nagios Core is stable."

"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."

"The most valuable features are the reports and the way it generates the report in a graphical manner."

"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."

More Nagios Core pros

"The satellite service installed on remote computers is an easy way to add clients, plus it's easy to deploy and to configure the licence is perpetual and not linked to one computer, so it's possible to remove a licence from one computer and use it on another with no extra cost"

"The possibility to develop your own VB scripts."

Cons

"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."

"I believe Nagios Core will need to provide an option for big data platforms in the future."

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."

"The mapping is a little hard."

"t was a little hard to get our setup represented in the configuration."

"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."

"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."

"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."

More Nagios Core cons

"The satellite service installation file could be separated from the server one. It would reduce the size of the file, and reduce the time to deploy on weak connections."

"Basic monitoring on Unix was working really well but it didn't really help under machines in Windows Domain Controller."

Pricing and Cost Advice

"The enterprise version has technical support. The version we are using is free."

"The solution is expensive."

"It's free."

"Nagios Core is an open source solution, and there are no licensing fees."

"We are using the free version of Nagios Core."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"It's free."

"The product is cheaply priced."
