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

"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."

"We are using Nagios Core on a VM and it's working very well, even though the specs of the VM are very low because it doesn't require much storage."

"Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."

"The reporting structure and the feature set are valuable to me."

"Its an awesome product to use."

"The most valuable feature depends on the project; it's great if you need to check to ensure a service is running 24/7, I can use the full solution for free, and it's flexible."

"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."

"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."

More Nagios Core pros

"The possibility to develop your own VB scripts."

"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"

Cons

"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."

"It is a bit slow due to latency."

"I would like to see more training videos."

"Application level monitoring is limited."

"We're using the free version, which limits us in terms of the things that we can do."

More Nagios Core cons
