SNMP pf object missing (bsnmpd)
-
i was watching this video https://www.netgate.com/resources/videos/monitoring-pfsense-24-with-snmp.html
and i configured snmp with the MibII and PF modules
but i see no output about pflocation := "Home" contact := "---------------" read := "-------------" system := 1 # pfSense %snmpd sysDescr = "pfSense pfSense.kiokoman.home 2.5.0-DEVELOPMENT pfSense FreeBSD 12.0-RELEASE-p10 amd64" begemotSnmpdDebugDumpPdus = 2 begemotSnmpdDebugSyslogPri = 7 begemotSnmpdCommunityString.0.1 = $(read) begemotSnmpdCommunityDisable = 1 begemotSnmpdPortStatus.127.0.0.1.161 = 1 begemotSnmpdLocalPortStatus."/var/run/snmpd.sock" = 1 begemotSnmpdLocalPortType."/var/run/snmpd.sock" = 4 # These are bsnmp macros not php vars. sysContact = $(contact) sysLocation = $(location) sysObjectId = 1.3.6.1.4.1.12325.1.1.2.1.$(system) snmpEnableAuthenTraps = 2 begemotSnmpdModulePath."mibII" = "/usr/lib/snmp_mibII.so" begemotSnmpdModulePath."pf" = "/usr/lib/snmp_pf.so"

from the BEGEMOT-PF-MIB.txt
pfStatus OBJECT IDENTIFIER ::= { begemotPfObjects 1 }

pfStateTable OBJECT IDENTIFIER ::= { begemotPfObjects 3 }
pfSrcNodes OBJECT IDENTIFIER ::= { begemotPfObjects 4 }

pfLabels OBJECT IDENTIFIER ::= { begemotPfObjects 11 }but none of this are available to me, am i missing somethig ?
same output for 2.4.5 -
@kiokoman maybe you didn't disable the net-snmp service?

nope, it's not running and not even configured, i have installed it only to have snmpwalk
-
@kiokoman I found that you need to select Host Resources module too
-
yes, tnx victor you are right.
i think it should be mentioned or set it as mandatory like MibII ? -
@kiokoman Please create redmine issue for this
https://docs.netgate.com/pfsense/en/latest/development/bug-reporting.html -
Fix:
https://redmine.pfsense.org/issues/10470#note-1 -
nice !

ok i was at work and i didn't have the time to check this carefully, there is still a problem or i don't understand how it work, there is no data about pf or i don't understand how to grab it.
we only have the description
?for example pfStatus OBJECT IDENTIFIER ::= { begemotPfObjects 1 }, this is still missing
uhm i found some info here http://www.circitor.fr/Mibs/Html/B/BEGEMOT-PF-MIB.php#begemotPf
if i do
snmpwalk -v2c -c public 127.0.0.1 1.3.6.1.4.1.12325.1.200
i see the data, so i suppose that pf stuff it's under
SNMPv2-SMI::enterprises.12325.1.200
maybe that patch is not needed @viktor_g
what i think is "pfStatus":
snmptranslate 1.3.6.1.4.1.12325.1.200.1.1
this translate to:
SNMPv2-SMI::enterprises.12325.1.200.1.1so
snmpwalk -v2c -c public 127.0.0.1 1.3.6.1.4.1.12325.1.200.1.1 SNMPv2-SMI::enterprises.12325.1.200.1.1.1.0 = INTEGER: 1 SNMPv2-SMI::enterprises.12325.1.200.1.1.2.0 = Timeticks: (27057300) 3 days, 3:09:33.00 SNMPv2-SMI::enterprises.12325.1.200.1.1.3.0 = INTEGER: 1 SNMPv2-SMI::enterprises.12325.1.200.1.1.4.0 = STRING: "0xdce55c76"
i didn't noticed before but under the video there is a link with examples inside
https://www.netgate.com/assets/downloads/hangouts/201803 _ -_ pfSense_Hangout _ - _ mib-example.txt
(remove the spaces from the link, for some reason the forum remove one underscore without it)A brief example of how a name is mapped to an OID using MIB files. bla bla bla bla... snmpget -M +/usr/share/snmp/mibs/ -v2c -c public 127.0.0.1 BEGEMOT-PF-MIB::pfStatusRunning.0
that's it ... the -M flag
[2.5.0-DEVELOPMENT][root@pfSense.kiokoman.home]/root: snmpget -M +/usr/share/snmp/mibs/ -v2c -c snmp-pfsense 127.0.0.1 BEGEMOT-PF-MIB::pfStatusRunning.0 BEGEMOT-PF-MIB::pfStatusRunning.0 = INTEGER: true(1)
and that is how you lose 6 hours on something because you don't see a f**ing link
well at least partially.. you always learn something new if you dig deeper -
@kiokoman thank you for useful info!
