=== Fully Integrated SNMP Monitoring ===

This page is dedicated to some %%FreeBSD%% SNMP development for BSNMP http://people.freebsd.org/~harti/bsnmp/, the native %%FreeBSD%% lightweight SNMP agent.
For the time being we have the SNMP instrumentation for HOST-RESOURCES-MIB, TCP-MIB and UDP-MIB. For the latest details & patches please see the SnmpMonitoringModulesStatus page.

Short term topics list:

  * **Host%%%%Resources MIB**. This might benefit from some additional stuff (used i-nodes for the files systems, ...). We have a private MIB to put it in (/usr/share/snmp/mibs/{FREEBSD,BEGEMOT}-MIB.txt). __//Host%%%%Resources MIB//__ is: http://www.ietf.org/rfc/rfc2790.txt

The current code is located here (just for browsing):
[[http://perforce.freebsd.org/depotTreeBrowser.cgi?FSPC=//depot/projects/soc2005/bsnmp/usr.sbin/bsnmpd/modules/snmp%5fhostres/&HIDEDEL=YES|Perforce Depot for HR-MIB]]

  * **Ethernet MIB**. Here we will need help from interface hackers to get the drivers actually deliver the statistics. Ether%%%%Like-MIB is: http://www.ietf.org/rfc/rfc3635.txt

  * **IPv6 MIBs**. We have an almost complete IPv4 MIB-2 (well, I (harti) did not track MIB additions during the last two years so may have missed something). Current IETF mibs:

| MIB | IETF URL | Notes | Implementation |
| TCP-MIB | http://www.ietf.org/rfc/rfc4022.txt | unified v4 and v6 | [[http://perforce.freebsd.org/depotTreeBrowser.cgi?FSPC=//depot/projects/soc2005/bsnmp/usr.sbin/bsnmpd/modules/snmp%5ftcp%5fudp46&HIDEDEL=YES|Perforce Depot for TCP-MIB and UDP-MIB]] |
| UDP-MIB | http://www.ietf.org/rfc/rfc4113.txt | unified v4 and v6 | [[http://perforce.freebsd.org/depotTreeBrowser.cgi?FSPC=//depot/projects/soc2005/bsnmp/usr.sbin/bsnmpd/modules/snmp%5ftcp%5fudp46&HIDEDEL=YES|Perforce Depot for TCP-MIB and UDP-MIB]] |
| IP-MIB | http://www.ietf.org/rfc/rfc4293.txt | v4 & v6 | None yet |
| IP-FORWARD-MIB | http://www.ietf.org/rfc/rfc4292.txt | v4 & v6 | None yet |
| TUNNEL-MIB | http://www.ietf.org/rfc/rfc4087.txt | None | None yet |
| IPV6-ICMP-MIB | http://www.ietf.org/rfc/rfc2466.txt | v6 only | N/A |
| IPV6-MIB | http://www.ietf.org/rfc/rfc2465.txt | v6 only | N/A |
| TCP6-MIB | http://www.ietf.org/rfc/rfc2452.txt | v6 only - Obsolete | N/A |
| UDP6-MIB | http://www.ietf.org/rfc/rfc2454.txt | v6 only - Obsolete | N/A |

  * Row creation for the snmp_netgraph Node and Hook table (low priority).

Long term topics list:

  * SNMPv3 (this is tough)

  * snmp{get,set,walk,...)

  * remote configuration command line tool (I [harti] have ideas on this one).
