proc.num returns 0

[dan1]

I'm having issues getting proc.num to return anything other than 0 for certain services. Main one is Apache. Monitoring an open port isn't good enough, so I want to check the process is alive.

See below for info:

[[root@servername ~]# sestatus
SELinux status:                 disabled

[[root@servername ~]# cat /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=permissive
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

Am I being really thick? What am I missing?

Fixed. Realised that Zabbix couldn't see any other processes than itself, so it would be permission related.

Need to set AllowRoot=1 in the zabbix agent config


I think this is something that should be mentioned in the documentation, as I couldn't find any mention at all!

Instead giving zabbix agent privileges you should add to zabbix account permission to be able check other processes status.

That does sound better than giving root access. How do you do it?
