Hello all,
I have a FortiGate device and couple of VDOMs on it. FortiGate was on version 6.x and monitoring worked normal both for the “box” (physical device) and for the VDOMs.
After software upgrade of FortiGate to version 7.2.7, monitoring of the FortiGate “box” works normal, but VDOMs are not monitored any more.
What I saw as well on LibreNMS is that the version on the FortiGate’s box itself is current (OS is 7.2.7), but when I checked VDOMs, on each there is the different version: 7.0.13 or 7.0.10 or 7.0.12 (note: while upgrading the FortiGate it is not possible to reach the end version in one step, e.g. from 6.x. first “jump” is to 7.0.10, then upgrade to 7.0.12, then 7.0.13, then last upgrade to 7.2.7 etc. as I remember the versions - upgrade path for FortiGate devices).
Maybe that is causing the issue, but I am not sure if I need to re-discover the VDOMs again so the OS version would be a good one.
Does anybody has a clue why is this happening and how I can tackle it?
Thanks in advance
Filip
