Hi All
I've got a support case open with F5 regarding an issue whereby their net-snmp implementation stops reporting F5 specific sysObjectID values.
This may be a recent 11.5+ version issue, as I've not run across it before, and it only seems to occur after making SNMP related configuration changes.
e.g. on virtual editions,
SNMPv2-MIB::sysObjectID.0 = OID: F5-BIGIP-SYSTEM-MIB::bigipVirtualEdition
Starts to become at some point,
SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-TC::linux
Observium goes back to treating the system as a Linux box.
The F5 specific OID's are still pollable, so the best fix seems to be a quick poll against F5-BIGIP-SYSTEM-MIB::sysGeneralChassisSerialNum.0 to determine if it's an F5 system.
Patch is simply,

I hope that helps.
