DESCRIPTION

This object holds the results of a trace performed via Sys::Trace.

METHODS

new($trace)

Initialises the object from a given trace. Normally called via the results method of Sys::Trace.

calls([$call])

Return a list of all the calls. The system call name will be filtered against $call if provided (either a string or a Regexp reference).

Each element in the list will be a hash reference of the form:

{
name => "/path/to/file", # filename, if relevant
call => "open", # system call name
systime => 0.000012, # time spent in call
walltime => 1277664686.665232 #
args => [ ... ] # arguments
errno => "ENOENT" # errno, if error occurred
strerror => "No such file or directory", # error string, if returned
pid => 1234, # pid being traced
return => -1
}

files([$path])

Return a list of files that were referenced by the system calls in this trace, optionally filtering on $path.

TODO

This is currently very basic, this module should provide the ability to perform analysis.
