OIDs for Fortigtate firewalls

Fortinet firewalls can be monitored using any SNMP capable device. You can look into CPU usage, memory usage, number of sessions, utilization on interfaces and so forth.

But it is not always easy to know how to do this. I needed to monitor CPU, memory and # of sessions on a firewall. Here are the OIDs to do so. Tested on FortiOS 3.0

CPU load	1.3.6.1.4.1.12356.1.8.0
Memory usage	1.3.6.1.4.1.12356.1.9.0
Number of current sessions	1.3.6.1.4.1.12356.1.10.0

These values can be added directly to SNMP tools such as PRTG and MRTG.
