Hi Enrique,
If you are using the cluster feature of the status module to monitor all
the systems from a single webmin server, then the information about
which monitors are up and down is already available on that master
server. It can be found in the file /etc/webmin/status/oldstatus , which
is a text file in which each line is in the format :

id=status

The 'id' is the ID of a monitor, and status is the result from the last
check. 0 = down, 1 = up, other numbers indicate other types of failures.
You can read that file easily in a webmin module with the read_file
funcion, which converts it into a hash.

The actual details of each monitored services are in files in the
/etc/webmin/status/services directory. You can either read those
directory, or make foreign calls from your module to the status module
to read them, with code like :

&foreign_require("status", "status-lib.pl");
$serv = &status::get_service($id):
