Creating a trigger for a text-based item

[nasomers]

Hello all!

I have created an item for updates/packages for Linux systems, which returns a text list of the packages and respective version.

I want to create a trigger that alerts when this item returns any text, but I can't get a trigger to work. I know that the item works as when I visit "Latest Data" I can see the text list of packages there.

Thanks so much!

Here's what I'm using for the item

UserParameter=system.sw.debianupdates-list,apt-get dist-upgrade -s  |sed -n 's/^Inst \(.*\) (.*/\1,/p' | tr '\n' ' '

you can look at this direction -
set the trigger with .nodata=0 or .nodata=1 for this item

for me the easiest way is to create a bash script

#!/bin/bash

CHECK=$(apt-get dist-upgrade -s |sed -n 's/^Inst \(.*\) (.*/\1,/p' | tr '\n' ' ')

if [[ -n $CHECK ]]; then
echo 0
else
echo 1
fi

and then set the trigger like this :
{server.office.local:system.sw.debianupdates-list.last(0)}=0

and if the script returns 0 when the check command is not null it will fire a trigger

Sorry, new to Zabbix. Could you expand on this a little? Thanks!

i never set a trigger for this but i think you can set a trigger like

{server.office.local:system.sw.debianupdates.nodat a(600)}=0

it will fire the trigger - but again im no expert either
i will always prefer making my own scripts.

Unfortunately I get an error trying to save that, says the trigger expression is invalid and cannot be used.

I want the trigger to list the packages in the actual alert on the dashboard. I have it configured now to alert when there are updates available at all and how many, but I want to know what the packages are so I can discern if they may be service affecting or not.

Thanks

you cant with the dash board because if you will have a
long string it will cut a half of it.
