=head1 OUTPUT

The returned value is a reference to an array. There is an entry in the array
for each collection gathered for each file server. Each entry in the array is
a reference to a hash, containing the following keys:

=over

=item B<hostName>

The name of the file server this data collection represents

=item B<collectionNumber>

The data collection number

=item B<probeTime>

The time the probe was initiated, measured in seconds since the Epoch
(00:00:00 UTC, January 1, 1970).

=item B<probeOK>

1 if the probe was successful, 0 if the probe failed.

=item B<data>

If the probe was not successful, this key will not exist. Otherwise, this
entry will contain a reference to a hash containing all of the data collected.
For details on the contents of this hash, and an example of printing it in a
readable format, refer to the B<xstat_fs_test> script in the B<examples>
directory.
