Great Plugin, but could be better

First of all a Great PLugin, which lets you monitor your Fortigate Device. Works with Fortigate 600D (5.4.8). To make it work with Fortimanager (5.6.2) all you have to do is change ( /^(FL|FAZ)/ to ( /^(FL|FAZ|FMG)/ otherwise it will not work for Fortimanager. Unforntunalty the disk check is not working for Fortigate, because it’s not defined in the oids and I wasn’t able to get the right oid. For the error from mugundan28 all you have to do is to provide the right permissions to /var/spool/nagios/ramdisk/FortiSerial, a chown nagios:nagios did the trick for me.
