NAME

kdump - display kernel trace data

SYNOPSIS

kdump [-dnlRT ] [-f file ] [-m maxdata ] [-t [cnis] ]

DESCRIPTION

Kdump displays the kernel trace files produced with ktrace(1) in human readable format. By default, the file ktrace.out in the current directory is displayed.

The options are as follows:

-d: Display all numbers in decimal.
-f file: Display the specified file instead of ktrace.out
-l: Loop reading the trace file, once the end-of-file is reached, waiting for more data.
-m maxdata: Display at most maxdata bytes when decoding I/O
-n: Suppress ad hoc translations. Normally kdump tries to decode many system calls into a more human readable format. For example, ioctl(2) values are replaced with the macro name and errno values are replaced with the strerror(3) string. Suppressing this feature yields a more consistent output format and is easily amenable to further processing.
-R: Display relative timestamps (time since previous entry).
-T: Display absolute timestamps for each entry (seconds since epoch).
-t cnis: See the -t option of ktrace(1).
