If you select PF module without Host Resources module on the Services / SNMP page
bsnmp doesn't return PF BEGEMOT-PF-MIB:

# snmpwalk -v2c -c public | grep pf
SNMPv2-MIB::sysDescr.0 = STRING: pfSense 2.5.0-DEVELOPMENT pfSense FreeBSD 12.0-RELEASE-p10 amd64
SNMPv2-MIB::sysName.0 = STRING:
IF-MIB::ifDescr.5 = STRING: pflog0
IF-MIB::ifDescr.6 = STRING: pfsync0
IF-MIB::ifName.5 = STRING: pflog0
IF-MIB::ifName.6 = STRING: pfsync0

You also need to select the Host Resources module to get it:

i have done some research and i found this
i have discovered that pf data is indeed present, the Host Resources module only add hrStorageDescr but there is actually no data
all the pf data are indeed available with

snmpwalk -v2c -c public

this lead to


therefore maybe this patch is not needed

more research done, i found this under the slide of jim that, sadly, i didn't noticed before
if we use snmpget/walk/table we need the -M flag else we can't use the correct name

snmpget -M +/usr/share/snmp/mibs/ -v2c -c public BEGEMOT-PF-MIB::pfStatusRunning.0

[2.5.0-DEVELOPMENT][root@pfSense.kiokoman.home]/root: snmpget -M +/usr/share/snmp/mibs/ -v2c -c snmp-pfsense BEGEMOT-PF-MIB::pfStatusRunning.0
BEGEMOT-PF-MIB::pfStatusRunning.0 = INTEGER: true(1)
