+.Dt bsnmp-jails 8
+.Os bsnmp-jails
+.Sh NAME
+.Nm bsnmp-jails
+.Nd an SNMP module provides statistics regarding FreeBSD jails running on the system.
+.Sh DESCRIPTION
+.Nm
+is a module for
+.Xr bsnmpd 1
+which monitors network and other statistics for FreeBSD jails running on the system.
+These statistics are gathered by the module.
+.Pp
+.Sh MIBS
+The counters will be available as a table under the following MIB:
+.Bd -literal -offset indent
+ .1.3.6.1.4.1.12325.1.204
+.Ed
+.Pp
+Or if the appropriate MIB.txt files have been installed:
+.Bd -literal -offset indent
+ enterprises.fokus.begemot.jails
+.Ed
+.Pp
+The following SNMP MIBs are available for use (where X is the counter index):
+.Bl -tag -width Fl
+.It Ar jails.jailCount
+The number of jails running on the system.
+.It Ar jails.jailTable.jailEntry.jailIndex.X
+The index of the jail in the table.
+.It Ar jails.jailTable.jailEntry.jailHost.X
+The hostname of the jail.
+.It Ar jails.jailTable.jailEntry.jailInOctets.X
+The number of octets received by the jail over the network.
+.It Ar jails.jailTable.jailEntry.jailInPackets.X
+The number of packets received by the jail over the network.
+.It Ar jails.jailTable.jailEntry.jailOutOctets.X
+The number of octets sent by the jail over the network.
+.It Ar jails.jailTable.jailEntry.jailOutPackets.X
+The number of packets sent by the jail over the network.
+.It Ar jails.jailNetworkFilter
+A tcpdump style filter for the network traffic. Only matched traffic
+is counted in the jail statistics.
+.El
+.Sh OPTIONS
+To activate the
+.Nm
+module you must load the module in
+.Pa /etc/snmpd.config
+.Pp
+You can use the jailNetworkFilter SNMP MIB to configure which traffic
+to count in the jail network statistics.
+.Sh EXAMPLES
+This example configures the module, and excludes traffic to/from the
+10.0.0.0/8 network from the network monitoring.
+.Pp
+The following would be added to
+.Pa /etc/snmpd.config:
+.Bd -literal -offset indent
+begemotSnmpdModulePath."jails" = "/usr/local/lib/snmp_jails.so"
+%jails
+jailNetworkFilter = "not net 10.0.0.0/8"
+.Ed
+.Sh SEE ALSO

+.Xr tcpdump 1
