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 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:
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
