## NAME
       devlink-monitor - state monitoring

## SYNOPSIS
       **devlink** **monitor** [ **all** | _OBJECT-LIST_ ]



## DESCRIPTION
       The **devlink** utility can monitor the state of devlink devices and ports continuously. This op‐
       tion has a slightly different format. Namely, the **monitor** command is the first in the command
       line and then the object list.

       _OBJECT-LIST_ is the list of object types that we want to monitor.  It may contain **dev**, **port**,
       **health**, **trap**, **trap-group**, **trap-policer**.

       **devlink** opens Devlink Netlink socket, listens on it and dumps state changes.
