+
+.SH DESCRIPTION
+The
+.B ip
+utility can monitor the state of devices, addresses
+and routes continuously. 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.
