zabbix 3.4.0 - unsupported value (0)

[mvrk]

Hi,

I have script that is currently returning 0 for a certain item, and it was working with zabbix agent 3.0.9, but now with 3.4.0 i get unsupported:

zabbix_agentd -t "syslog.errors[scsi 2]"
syslog.errors[scsi 2] zabbix_agentd [87101]: Warning: 0
[m|ZBX_NOTSUPPORTED] [0]

The item configured on zabbix is Numeric (unsigned)

Any ideas?

Could try increasing log level and looking into Zabbix log on agent, what does it say?

I configured log level 5, but nothing much appears:

What if you replace you script contents to printf 0
Does it work then ?

[mvrk]

Its a bash script.

returns values using echo

ex: echo "0"

Already did, same error.

We have the same problem here

I created issue https://support.zabbix.com/browse/ZBX-12594

OK, they say this is not bug, this is feature,
now they check if errorlevel is not 0 and if not- then script failed.
this means grep or find are usually failed and almost all scripts have to be rewritten by at least edding exit 0 ..

this is crazy...
