Devices > Graphs > CPU - Missing graphs for most devices

Hi. New to LibreNMS, and new installation. Having successfully added a number of devices (eg 5 of them), we only see graphs for two of these devices when navigating from the main menu Devices > All Devices > {group name} > {Graphs page menu} > CPU (same problem for Memory and others).

However, when we navigate from the main menu to Health > Processor (or Memory), we do see grpahs for all devices.

This is a fresh install of [1.59-15-g891d6966d] on Ubuntu 18 LTS, and we have not other known issues with the system. All of the devices we are monitoring so far are FortiGates vis SNMP v3 (unauthenticated) over private network routing.

I’d add more screenshots but apparently only allowed to add one as a new user.

Added to the original post

Try run some manual SNMP polls, for example #Not discovering cores, just 1 CPU

You could also see if SNMPv2 gains any different result. check firmware is latest on fortigate
