Inventory OS Information Linux

[michaelp]

Hi,

Just started to use Zabbix coming from Nagios, is there a way of finding out in the Inventory the OS Version ? Or OS Full version ?

I would like to know which version of Linux is running

Host Group OS
xxx-xxx Linux Linux version 6.5.0-3-amd64

What I would like to see is the version of Linux

cat /etc/os-release | grep VERSION

VERSION_CODENAME=trixie

Would I need to create a new ITEM and how do I assign the NEW ITEM to all machines ?


Also If a server needs a reboot I normally run this script

#!/bin/bash
if [ -f /var/run/reboot-required ]; then
echo 'reboot required'

fi

Thanks if you can help me

Yes you need to create a new item to obtain that info. You can use vfs.file.contents item and some preprocessing to get version name out of it. Then also check the box of "populate inventory", so you can see that info in inventory page. As this probably does not change very often, you can set quite long update period like 1d or something.. Place it to a template, that is added to all hosts.

For second case you can use vfs.file.exists item to check if that /var/run/reboot-required file is present and then build a trigger on top of it to notify you... and then you can even build an action to reboot automatically or add a script, that you can run manually from problem menu...

Thanks for this,

I create the following item vfs.file.contents[ /etc/os-release]
I take it that I can use the Preprocessing to only return this value VERSION_CODENAME=trixie or just trixie ?

I have tried to match a regular expression but produces all of the line i.e


NAME="Debian GNU/Linux"
VERSION_CODENAME=trixie
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

I just want VERSION_CODENAME=trixie or everything after VERSION_CODENAME= but not ID=debian

preprocessing -> regular expression -> VERSION_CODENAME=(.*) -> return value \1
Should work... At least works in my computer...

Tried that and get the following

• cannot perform regular expression "VERSION_CODENAME=(.*) " match for value of type "none": pattern does not match

Not sure what I am doing wrong ?

Are you sure, you have exactly "VERSION_CODENAME=trixie" there? You have there options to test and pull data from host directly...

I removed the item and then re=added VERSION_CODENAME=(.*) and this seems to work

[michaelp]

Looks like I used the wrong key

vfs.file.regexp[/etc/os-release,VERSION_CODENAME=(.*)] This now produces VERSION_CODENAME=trixie which is what I needed

I can play around with syntax and hopefully just get
trixie

Thanks for you help

You can use vfs.file.regexp as well.. There are no right or wrong.. if it works, then it works..
If you just want the captured name, then just set the output value... vfs.file.regexp[/etc/os-release,VERSION_CODENAME=(.*),,,,\1]

[michaelp]

fs.file.regexp[/etc/os-release,VERSION_CODENAME=(.*),,,,\1] this is perfect and now produces a list of machines that need upgrading.

Just working on the "needs rebooting" and this will make things easier !

Can't you use zabbix_agent2 and query for system.sw.os[name]?

# zabbix_agent2 -t system.sw.os[name]
system.sw.os[name] [s|Debian GNU/Linux 13 (trixie)]

Sorry for digging up an old thread

system.sw.os[name] [s|Debian GNU/Linux 13 (trixie)]

Yes you can, still need to do some preprocessing to narrow down to required release name..

This is my simple item. Maybe not the best, but it works
