NAME
       dropwatch - kernel dropped packet monitoring utility

SYNOPSIS
       dropwatch [-l <method> | list]

DESCRIPTION
       dropwatch dropwatch is an interactive utility for monitoring and recording packets that are dropped by the kernel

OPTIONS
       -l <method> | list
	      Select  the  translation method to use when a drop alert arrives.  By default the raw instruction pointer of a drop location is out-
	      put, but by the use of the -l option, we can assign a translation method so that the instruction	pointer  can  be  translated  into
	      function names.  Currently supported lookup methods are:

       kas - use /proc/kallsyms to lookup instruction pointers to function mappings

INTERACTIVE COMMANDS
       start  Tells the kernel to start reporting dropped packets

       stop   Tells the kernel to discontinue reporting dropped packets

       exit   Exits the dropmonitor program

       help   Displays summary of all commands

       set alertlimit <value>
	      Sets a triggerpoint to stop monitoring for dropped packets after <value> alerts have been received
