get_attributes

Return the attributes supported by this module:

uids

Allows restricting the user ids (see lsof(8) for the -u parameter).

    $dbh->{sys_openfiles_uids} = [scalar getpwuid $<];
    $dbh->{sys_openfiles_uids} = [$<]; # all opened by myself

pids

Allows restricting the process ids (see lsof(8) for the -p parameter).

    $dbh->{sys_openfiles_pids} = ['^' . $$]; # everything except the current process

filesys

Allows restricting the scanned file systems (see lsof(8) for the +f parameter).

    $dbh->{sys_openfiles_filesys} = [qw(/usr /var)];

collect_data

Retrieves the data from the lsof command and put it into fetchable rows.
