NAME
dropwatch - kernel dropped packet monitoring utility

SYNOPSIS
dropwatch [-l method | list]

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

OPTIONS

-l method | list, --lmethod method | list
    Select the translation method to use when a drop alert arrives. By default the raw instruction pointer of a drop location is output, 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:

    list
        Show all supported methods.

    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.
