Regarding pxe boot monitoring on linux

[ssindhe]

Hi someone,

How to begin with the pxe boot monitoring using nagios, I want to create a plugin which monitors pxe?

OS: Linux
Servers

Depends on how far you want to go, there are many moving parts. The simplest thing would be to monitor the services required independently then maybe create a service with all those individual parts as dependencies.

check_dhcp deals with that bit
There are a few options on the Exchange for monitoring TFTP, even some that it appears can try to grab your boot file

How complex do you need to get?

Hi,

Thanks, Yeah I see check_tftp scripts for monitoring tftp. But I want to know where do I have to create this file and dump this code in?

in /etc? or /usr?

[jdalrymple]

Depends on your configuration. They can be anywhere, but the location is usually referenced by the $USER1$ macro.

Can you find your resources.cfg and see what that macro references?

Code: Select all

[jdalrymple@localhost ~]$ grep \$USER1 /usr/local/nagios/etc/resource.cfg
$USER1$=/usr/local/nagios/libexec

Your resource.cfg may be elsewhere, this is for a default install of NagiosXI

Great, Thanks a lot, I found the reference, it says
$USER1$ = /usr/lib64/nagios/plugins

For $USER2$ it refers to event handlers.

Now, do you want me to copy this python script of check_tftp into /usr/lib64/nagios/plugins? will that help me in monitoring the pxeboot?

Unfortunately, that is a loaded question because every setup of nagios is different. Usually you would place it in the plugins directory, which on your server looks like it is at

Code: Select all

/usr/lib64/nagios/plugins

Here is a link to Nagios Documentation
http://nagios.sourceforge.net/docs/nagi ... n/toc.html

Also, if you are completely new to Nagios, you may want to check out Nagios XI, which really reduces the learning curve in getting up and running and creating the configuration files

I have a check_tftp python code, but when I compile it display, syntax error!!

Can someone please get me a check_tftp code, with no errors. not specific to python but any code is fine.
