$ udevadm monitor --udev
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
udevadm monitor [options]
Listens to the kernel uevents and events sent out by a udev rule and prints the devpath of the event to the console. It can be used to analyze the event timing, by comparing the timestamps of the kernel uevent and the udev
event.
-k, --kernel
Print the kernel uevents.
-u, --udev
Print the udev event after the rule processing.
-p, --property
Also print the properties of the event.
-s, --subsystem-match=string[/string]
Filter kernel uevents and udev events by subsystem[/devtype]. Only events with a matching subsystem value will pass.
-t, --tag-match=string
Filter udev events by tag. Only udev events with a given tag attached will pass.
