Newbie's first custom UserParameter

[snakefox]

Hello.
I'm trying to set up a custom UserParameter for a Linux server. I've made the necessary changes:

UserParameter=disk.partition.workload[*],df -k | grep $1 | awk '{print $5}' | sed 's/.$//'

The idea is that I ask about a specific file system and get in return an integer which I then use in Zabbix triggers. I've tested the command itself and it works exactly as I want it to. But when I try to get the result through Zabbix (or try to test it with following)

zabbix_agentd -t disk.partition.workload[/pcap]

the result I get is the entire, unformatted string:

/pcap 54476506720 48636767680 3105006112  94% /pcap

I don't understand what causes this change and how do I fix it.

Zabbix agent is parsing the $5 in the awk command to an empty string (because there is only one parameter given in the item). You need to use double $ as mentioned in the documentation (https://www.zabbix.com/documentation...ser-parameters) or, just like you did, use an external script.

Seems to break just before awk...
You do not mention version of Zabbix, but I tested on 6.0.9 and agent2 and it does the same... But I cannot think of any good solution, too many other things to deal with...

Sorry, I am using zabbix_agentd (daemon) (Zabbix) 4.4.9.
Tried using a bash workaround:

df -k | grep $1 | sed 's/ */ /g' | cut -d" " -f 5 | sed 's/.$//g'

Worked, so it was definitely awk's fault. Which is weird, because if I put awk in a script and launch the script in the UserParameter, it works.

Huh, this'll hopefully teach me to read documentation better.
Thanks!
