Nagios is a good monitoring system, but its pricey.

You have Nagios XI (free version) You can use this to monitor up to 7 nodes.

Munin is a monitoring system that dates back a very long time. In fact, it's a fundamental monitoring system that most Linux based servers have installed. The fact you do not know what Munin is, is well - pretty astounding to say the least. Here's a link for you to get educated on Munin: http://munin-monitoring.org/ I would not suggest Munin however, as a primary platform for monitoring services. There are many far better suited and readily available applications. One of them mentioned is Nagios. Nagios is also an age-old platform that works very well and is even better when you can pair it with a platform that can visualize the data (one of Nagios' pitfalls is it's pretty much a wall of text in an era where having visualization can help you address problems faster). I could point you to monitoring systems like Zabbix or Grafana but the reality is that it all comes down to how you want your monitoring data presented. Do you want that single pane of glass graphical overview with easily visualized data, a hybrid of visualized data and contextual data, or simply contextual data? Everyone here will tell you Nagios - even I did but Nagios by itself is just not enough anymore but it should be the foundation.

I guess it's because of the fact I have not done much with Linux . Used it and know how it works, but not my operating system nor using it.

Hi yes is there any nice monitoring system with visualized data?

https://mathias-kettner.de/check_mk.html - is good .nagios based with integration for graphing and wato config wizard

hi on free version show network monitoring?
Posted by gnusys, 02-22-2017, 10:59 AM
yes it will show interface data and graph it

He's right > add my name to the list

Nagios with Icinga is really best option, you can set any kind of monitoring by creating your own Nagios plugins, we are providing such customised solution to our Dedicated server clients and its working well for them.

hi guys i just want want monitor our rack network usage which version or Nagios plugin should be install?

No, no, no and no. Nagios is a mess, both setup wise and configuration wise. It's a ton of bloat, really. The best answer is going to be write your own. It doesn't take much to get php configured to do the port monitoring, and you can use that as a base for everything. RBL, disk usage, load, email queue, everything.

I won't argue with you here @whmcsguru - the best solution is to of course create your own solution. However, the original poster did not seem capable of that and I don't think one rack is exactly worth the time or money to have your own monitoring system. The way I see it is that in 2002 I would have been fine with text reports and the old fashioned CLI style monitoring of Nagios and the graphs generated by it but today with an infinitely more complex system it's easier to visualize the data in "pretty" graphs and reports with monitoring points being able to be tapped (or clicked) to delve deeper past an overview screen - the single pane of glass approach. Heck, I like that in everything now; automation through clear, concise, and visually appealing single pane of glass interfaces is far better than walls of text but that's just due to complexities of systems. I have found those with less complex systems prefer the exact opposite but I understand - single pane of glass interfaces can be distracting to those with simple deployments. There was a whole thread on this subject a while back that listed pretty much every "off the shelf" monitoring system you could probably find. And that's the reason @hichkas, no one has said anything more than Nagios because what you might like to monitor your rack is going to be different from say what @whmcsguru or we use. There are a lot of us who have developed proprietary systems and concurrently use "off the shelf" monitoring systems too and they are each different and tailored through many hours to what each company needs. All any of us can say is "start with Nagios and go from there." Personally, in "off the shelf" monitoring systems, Grafana can turn a wall of text worth of data into visualized easy to understand data in a single pane of glass.
