Linux – Observium and SNMP

I have Observium installed but I can't seem to get the unix-agent to get MySQL, Apache and other statistics.

I have the unix-agent enabled under the Poller Modules. I have also tested and ensured the server-status page could be reached.

ls -la /usr/lib/observium_agent/local
total 76
drwxr-xr-x 2 root root  4096 Jul 11 12:45 .
drwxr-xr-x 3 root root  4096 Jul 10 23:13 ..
-rwxr-xr-x 1 root root  2910 Jul 11 12:43 apache
-rwxr-xr-x 1 root root   372 Jul 11 12:43 hddtemp
-rwxr-xr-x 1 root root 51594 Jul 11 12:43 mysql
-rwxr-xr-x 1 root root    64 Jul 11 12:45 mysql.cnf
-rwxr-xr-x 1 root root   116 Jul 11 12:44 temperature

and

ls -la /usr/bin/observium_agent
-rwxr-xr-x 1 root root 13584 Jul 11 12:54 /usr/bin/observium_agent

and
