[pfSense Support] SNMP oid's for bandwidth
Hi, I'm trying to monitor in / out bandwidth in bits on wan interface but are having some problems finding the right SNMP oid. I found this one: http://cvstrac.pfsense.com/tktview?tn=257 but the OID i'm trying doesn't return anything. Does anyone have any better suggestions for bandwidth monitoring on pfsense from an nagios server? Regards Stale Johnsen
Re: [pfSense Support] SNMP oid's for bandwidth
to measure bandwidth used I use a script that checks the difference between bytes passed from poll A to poll B. I can point you to the plugin I use if you'd like. gives results like: vr0:UP (131.0KBps/8.0KBps) and I get alarms in my email when I pass too much traffic like you'd expect: * Nagios * Notification Type: PROBLEM Service: Interface Status - vr0 Host: pipboy Address: 192.168.2.1 State: WARNING Date/Time: Tue Sept 29 08:02:33 EDT 2009 Additional Info: vr0:UP (WARN 1490.2KBps/56.2KBps) The OID it uses is just off the IF-MIB if I remember right. and most devices regardless of OS tend to respond to polls on the .1.3.6.1.2.1 trees, especially .1.3.6.1.2.1.2.2 and .1.3.6.1.2.1.25 , the first of which is the one you're looking for for interface information. 2009/9/29 Ståle Johnsen stale.john...@smartit.no Hi, I'm trying to monitor in / out bandwidth in bits on wan interface but are having some problems finding the right SNMP oid.

I'm not sure about Nagios for graphing, however here is what my Cacti poller shows. Data Source: x.x.x.x/fxp0 (In) RRD: /var/www/data/graphs/networks/rra/X_in_1.rrd Action: 0, OID: .1.3.6.1.2.1.2.2.1.10.1 (Host: x.x.x.x, Community: **) Data Source: x.x.x.x/fxp0 (Out) RRD: /var/www/data/graphs/networks/rra/X_out_2.rrd Action: 0, OID: .1.3.6.1.2.1.2.2.1.10.1 (Host: x.x.x.x, Community: **) Curtis LaMasters http://www.curtis-lamasters.com http://www.builtnetworks.com 2009/9/29 Ståle Johnsen stale.john...@smartit.no: Hi, I'm trying to monitor in / out bandwidth in bits on wan interface but are having some problems finding the right SNMP oid.

Does anyone have any better suggestions for bandwidth monitoring on pfsense from an nagios server? I use Cacti to monitor mine, and it polled the pfSense box when I setup the graphs and listed all the interfaces, and I just chose them from there. If you need to find the actual OID, you may have to do something like: snmpwalk -v 2c -c yourcommunity pfsense ip mib-2.interfaces And then use the resulting OIDs to see what you want (You can also use -On to find the numeric OIDs instead of their textual counterparts) IIRC, depending on the system, the wan interface will almost never be the same due to various ways the interfaces are detected by the system. You'll have to look in that snmpwalk output, find the interface name which corresponds to your WAN interface, and then use the traffic counters for that interface index number. For example, my WAN would show up like: IF-MIB::ifDescr.8 = STRING: vlan0 So then the various counters that end in .8 would be for that interface. (IF-MIB::ifInOctets.8, IF-MIB::ifOutOctets.8, etc) Jim - To unsubscribe, e-mail: support-unsubscr...@pfsense.com For additional commands, e-mail: support-h...@pfsense.com Commercial support available - https://portal.pfsense.org

Hi, This plugin looks perfect for what i'm looking for. Can you point me to it and paste which OID's you are using? Thank you in advance.
