I guess you should set it in conf/plugin_status.xml file as follows:
<configuration plugin="status">
<settings name="settings">
<set name="interval">60</set>
<!-- This can either be a path on the local filesystem, or an ftp directory.
To use an ftp directory, use this syntax: ftp://username:password@host/path/to/status.xml
-->
<set name="output_file">ftp://fastserv:password@ftp.fastserverfiles.com/public_html/sosclan/status/status.xml</set>
</settings>
</configuration>
Don't forget to replace password with the correct one.
