proc.num problem

[wld]

Hi,

I have problem with proc.num[sshd].
When I run zabbix_get from zabbix server:
./zabbix_get -s 192.168.x.x -k 'proc.num[sshd]'
0
But when i run ps on monitored server:
ps -ef|grep -c sshd
3

I found the problem.
SELinux was in enforced, I've changed it to Permissive.

Best regards.
