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 bsnmpd 1, .Xr tcpdump 1 .Sh AUTHOR .An Stef Walter Aq stef@memberwebs.com
