UserParameter not returning expected

[Durwin]

I am using zabbix-agent-2.2.8-1.fc21.x86_64. I added this line directly from the example into /etc/zabbix_agentd.conf. I just renamed key. I then restarted zabbix-agent.service.

UserParameter=dir.size[*],dir="$1"; du -s -B 1 "${dir:-/tmp}" | cut -f1

I then ran zabbix_get.

zabbix_get -s 127.0.0.1 -p 10050 -k "dir.size[/home/userdir]"

The value I get is 4096 which is the size of a directory structure. The 'du' command as supplied should return the size of the entire directory including all sub directories.

Any help on this?

Thank you,

Durwin

Hi

Have you sure Zabbix have good rights on directory ?

If I try your UserParameter with this modification
UserParameter=dir.size[*],dir="$1"; du -s -B 1 "${dir:-/tmp}" 2>/dev/null | cut -f1

> zabbix_get -s 192.168.130.206 -k dir.size[/tmp]
53248

Really, with root a du -s -B 1 /tmp returns
86016 /tmp

The difference is the size of files that Zabbix cannot acceded.

Hope that's help you.

Thank you for the reply. Shortly after I posted I recalled that zabbix runs as zabbixsrv. As soon as I set the SUID on 'du' all worked as expected.
