I'm relatively new to SNMP and currently trying to add somes snmp sensor from my fortigate device to prtg. I'd like to be able to monitor VPN state.
I followed this tutorial :
I have setup snmp v2 on one firewall. I have setup a device on prtg with the right ip and snmp info and some basic sensor like ping are working fine. I downloaded MIB file from my fortigate, converted them with paessler tool and put them in my prtg install. But when I try to add that sensor via "SNMP bibliothek" the sensor goes into "config", which usually take a matter of seconds, but there it juste get stuck, the progress bar looping again and again. I have let it run one full night for nothing.
I try to access my device with paessler SNMP tester and that worked fine (did a simple "scan interfaces").
Any idea of what I could do to understand what is happening ?
Thank you in advance
