Zabbix Agent can't return text value

[stevenfoo]

I have an agent 1.8x installed on one of unix machine.

For example

Userparamater=test,ps -ef | grep zabbix | tail -1 | awk '{print $9}'

When I test it with /usr/local/bin/zabbix_agentd -t test
it gives me ==> test [t|zabbix]

However in the audit reporting part, I encounter
items.error: Not supported by Zabbix Agent =>

No matter I change the item to text, character or anything else it is still not supported.

Any ideas?

Any update on this? I am having a similar issue

The following works just fine in the Zabbix_agentd.conf on my esx server

UserParameter=testtest,vdf -h -P

But when I try to grep to get just the info I need the item becomes unsupported

UserParameter=testtest,vdf -h -P | grep -E '/vmfs/volumes/494956d9-edbb9362-d658-003048c324a2' | awk '{ print $5 }'

Any help would be appreciated.

Hi,

check in zabbix_agentd.conf, following parm should be set: UnsafeUserParameters=1

Thanks Patrick

I tried that, it didn't help. But I did find the following.

The zabbix_agentd.log has the following as soon as i set UserParameter=testtest,vdf -h -P | grep -E '/vmfs/volumes/494956d9-edbb9362-d658-003048c324a2' | awk '{ print $5 }'

Error during version check: Permission denied(13): bad permissions on /dev/vmkcall.

does this mean that the zabbix_agentd dosn't have permission to run the command?

I figured it out it was a permissions issue on with the /dev/vmkcall. I ended up with the following script which will give me the free space in GB for the iscsi lun, on my esx server.


UserParameter=vdf, vdf -h -P | grep '/vmfs/volumes/4bba8646-7d9cc9d6-9114-a4badb147fc0' | awk '{ if (length($4) == 4) print substr($4,0,3); if (length($4) == 3) print substr($4,0,2); else if (length($4) == 2) print substr($4,0,1)}'
