=head1 NAME
wtf.pl - Grabs a small capture of the performance data for the local machine and sends the information to the VMPI maintainers
=head1 SYNOPSIS
wtf.pl [-runfor <time>] [-help|-?] [-man] -log <log> | -bad | -good
Options:
-bad Captures the data to the "bad" log (default)
-good Captures the data to the "good" log
-log Specifies the log to send
-runfor Specified the amount of time to sample for
-help|-? Display command line usage
-man Display full documentation
=head1 DESCRIPTION
B<wtf.pl> is for capturing information about your system when VMPI is
doing something "bad". The default behaviour is to capture 15 seconds
of data and send the performance log to the VMPI maintainers. You can
optionally run another capture to show a "good" situation for a
baseline to compare against.
=head1 BUGS
The logman program that is used by wtf.pl does not support the -rc
command properly, so I cannot register wtf.pl to automatically send
the log when the capture ends. Instead I must manually start/wait/stop.
