This option has a slightly different format. +Namely, the +.B monitor +command is the first in the command line and then the object list follows: + +.BR "ip monitor" " [ " all " |" +.IR OBJECT-LIST " ] [" +.BI file " FILENAME " +] [ +.BI label +] [ +.BI all-nsid +] [ +.BI dev " DEVICE " +] + +.I OBJECT-LIST +is the list of object types that we want to monitor. +It may contain +.BR link ", " address ", " route ", " mroute ", " prefix ", " +.BR neigh ", " netconf ", " rule ", " stats ", " nsid " and " nexthop "." +If no +.B file +argument is given, +.B ip +opens RTNETLINK, listens on it and dumps state changes in the format +described in previous sections. + +.P +If the +.BI label +option is set, a prefix is displayed before each message to +show the family of the message. For example: +.sp +.in +2 +[NEIGH]10.16.0.112 dev eth0 lladdr 00:04:23:df:2f:d0 REACHABLE +[LINK]3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast state DOWN group default + link/ether 52:54:00:12:34:57 brd ff:ff:ff:ff:ff:ff +.in -2 +.sp + +.P +If the +.BI all-nsid +option is set, the program listens to all network namespaces that have a +nsid assigned into the network namespace were the program is running. +A prefix is displayed to show the network namespace where the message +originates. Example: +.sp +.in +2 +[nsid 0]10.16.0.112 dev eth0 lladdr 00:04:23:df:2f:d0 REACHABLE +.in -2 +.sp + +.P +If the +.BI file +option is given, the program does not listen on RTNETLINK, +but opens the given file, and dumps its contents. The file +should contain RTNETLINK messages saved in binary format. +Such a file can be generated with the +.B rtmon +utility. This utility has a command line syntax similar to +.BR "ip monitor" . +Ideally, +.B rtmon +should be started before the first network configuration command +is issued. F.e. if you insert: +.sp +.in +8 +rtmon file /var/log/rtmon.log +.in -8 +.sp +in a startup script, you will be able to view the full history +later. + +.P +Nevertheless, it is possible to start +.B rtmon +at any time. +It prepends the history with the state snapshot dumped at the moment +of starting. + +.P +If the +.BI dev +option is given, the program prints only events related to this device. + +.SH SEE ALSO +.br +.BR ip (8) + +.SH AUTHOR +Original Manpage by Michail Litvak <mci@owl.openwall.com> +.br +Manpage revised by Nicolas Dichtel <nicolas.dichtel@6wind.com> |
