check_fortigate_session2

Project Notes

This script is a modification of "Check Fortigate CPU load" (or check_fortigate_cpu.pl) and the script check_fortigate_session

Test on fortigate 60C

Perhaps someone will find it useful.

It works for CPU and RAM usage, as well as active sessions.
Performance data is also produced.
For this script to work, SNMP needs to be enabled in your FortiGate config, both for the appropriate network interface and in the Config section.
The community name should be "public".

The "snmp" package should also be installed on the Linux side of things.
