I am in the process of integrating Solarwinds with our environment.
We are mostly an Aruba and Fortinet shop, with some Cisco and Palo sprinkled around.
So far I have not see any issues with Aruba Switches and APs, or Cisco Switches, or Palo Alto firewalls when polling those devices. It appears Solarwinds is well integrated with these platforms.
However, when it comes to FortiGate firewalls. There are some pieces of information that I couldn't get SolarWinds to populate. One of the main things is Hardware details, such as FAN status, PS status, FortiGate Serial Numbers (for asset management) OS Image name.
I have messed around with creating Custom UnDP, and I actually found the MIB in the SolarWinds MIB Browser application and created the fnSysSerial poller and assigned it to my firewalls, but It still fails to populate this information, even though the test was successful for this specific poller on the target device.
I also downloaded/installed THWACK Community Fortinet Pollers that get the information I hope to get, but no luck.
