Its very easy to setup a nagios system following your lecture for me bcoz I already have past tools admin experience with nagios core 3 integration with nrpe, snmp, nagvis, centreon, otrs,mrtg,rt, ndoutils and many more. thank you for this video. its really good
I am a big fan of your work... keep it swag!!! one of the best linux online teachers i've ever had... :D
Excellent video on configuring Nagios clients both Linux and Windows
At the point 8:42, I think you missed one step, which is add the "cfg_file=/usr/local/nagios/etc/objects/linuxclient.cfg" line into the nagios.cfg file. cheers!
thanks buddy. your comment saved my troubleshooting time.
So very nice I will be installing the whole Nagios software in my lab over the next few weeks and then see if my boss will be ok installing in prod.. Very cool.

Hi,Thanks for the excellent tutorial. Can we add multiple servers in a single nagios file.
Que bom está de volta.
Why did the simple tar xvf (without the 'z') work against the gzipped tarball? That was kind of weird.
will you plz tell me what's the difference of Typical ,custom and complete when installing ???
how to access nagios core web interface from another machine,not from the same machine it is installed in
Please also make video on how to configure nagios email alert notifications
Thanks for the Tutorial. I have a question regarding the current Version 4.0.2. The Xinetd Configuration doesnt show up under the Directory "Sample Config". Also searched the Xinetd directory and so on.. Yet nothing to find but online results. Whats the Procedure from here though? (Working on Cent OS8)
Hi,
I'm trying to setup my test nagios to check the disk space of another remote host. I've got it setup and checking. But to my surprise, it was checking the nagios server's local disk space instead of the remote host.Pls hlp me ASAP
Is there anyway to discover hosts automatically and add them in to config file using script? I would like to set up nagios for small company so adding all the servers manually is time consuming.
Thanks for the video. Does email notifications work out of the box or do we need to install Postfix ?
Can you please help me to install monitoring network on the RASPBERRY card to supervise some printout and some router through the SNMP protocol.
Thank you
after install xinetd it doesnt show in the sample-config directory, any ideas folks?

I have two instances.One is Nagios Server Monitor and another one is client where my Kafka service is running.I am able to monitor client host and using other monitor tool like Datadog able to monitor.
But I have not worked before with Nagios and do not know how to integrate Kafka service with it.
Please guide asap.
Thanks in advance
Hello, very good day, first of all congratulations and thank you for your videos, they are very good material to be able to learn more about this world of open source, sorry for the inconvenience, could you tell me to clarify a doubt that I have in my workplace I already have 16 windows computers with nsclient already installed, could you tell me how I could add each one separately to make monitored or flat if it is better all in just one thank you very much and sorry for the inconvenience
I have just noticed , that the linux-clienthost is also showing the same root partition size as the nagios-server root partition ! ,, same goes for the swap !
I have the same situation, I followed the tutorial but it gives all nagios server info not the client. Anyone know why it is like that?
thank you, really helpful
Please help I got an error whole Itype ./
Very nice... Thanks
Getting error no nsclient getting information
CHECK_NRPE: Error - Could not complete SSL handshake...
Please help me out from this error..thanks
how and why logged onto GUI with root?
super helpful.
Better setup all passwords in resource.cfg "$USER100$=temp123" ,and in commands.cfg add "USER100$" ... CGI is not reading the resource file so your passwords are more secure , you can also chmod resource file to 600 or 660.
miss you :)
Thanks a lot .
Jeez, where have you been? You owe us an explanation. :) Welcome back!
where you been 2 years many warm welcome to come back.
beautiful....
Found rpm way of installing that is much faster. Anyways thanks.

It seemed to be too resource intensive ..

Do you use two linux computers? or just one? I am a student who studying about nagios lately..
Honestly for someone that is not very good with linux and cli I found this to be very difficult to follow and I still cannot get my windows hosts to work with nagios. I like your style but you blew through that so fast... This video did not help me.
hey Tanya! i have a problem with setting up Nagios for Linux client, there is any way to contact you ?
