Fortigate + Solarwinds SNMP Traps ??

Hello, first post here sorry if I posted it in the wrong forum.

Fortigate:

Enabled SNMP

Syslog port 161

Traps port 162

All SNMP Events is enabled

Solarwinds Server:

Syslog port 161 (Solarwinds Syslog)

Traps port 162 (Solarwinds Trapviewer) 

I am testing with "diag log test" - which "fakes" different log levels. 

With this setup, I see everything in the syslog. But my trap viewer does not catch anything from the test. There is some sort of communication thought, because changes like IP on an Interface sends a trap that can be seen, likewise with Uptime/Config Change etc. 

Why am I only receiving some traps but not all? I want to see traps when Virus is blocked, IPS blocked etc. 

Hope you can help, if you need more information feel free to ask!
