SYNOPSIS

crashinfo [-d crashdir] [-n dumpnr] [-k kernel] [core]

DESCRIPTION

The crashinfo utility analyzes a core dump saved by savecore(8). It generates a text file containing the analysis in the same directory as the core dump. For a given core dump file named vmcore.XX the generated text file will be named core.txt.XX.

By default, crashinfo analyzes the most recent core dump in the core dump directory. A specific core dump may be specified via either the core or dumpnr arguments. Once crashinfo has located a core dump, it analyzes the core dump to determine the exact version of the kernel that generated the core. It then looks for a matching kernel file under each of the subdirectories in /boot. The location of the kernel file can also be explicitly provided via the kernel argument.

Once crashinfo has located a core dump and kernel, it uses several utilities to analyze the core including dmesg(8), fstat(1), iostat(8), ipcs(1), kgdb(1), netstat(1), nfsstat(1), ps(1), pstat(8), and vmstat(8).

The options are as follows:
-d crashdir
  Specify an alternate core dump directory. The default crash dump directory is /var/crash.
-n dumpnr
  Use the core dump saved in vmcore. dumpnr instead of the latest core in the core dump directory.
-k kernel
  Specify an explicit kernel file.
