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
