# This next call returns a list of systems available to the user. The

# syntax of this call is described at:

# http://$HOST/rpc/api/system/list_user_systems/

# In the code snippet below, we dump data about our systems, and we

# capture the ID of the first system we find for future operations.

my $systems = $client->call(’system.list_user_systems’, $session);

for my $system (@$systems) {

print Dumper($system);

}

print "\n\nCapturing ID of system @$systems[0]->{name}\n\n";

my $systemid = @$systems[0]->{id};

# This next call returns a list of packages present on this system. The

# syntax of this call is described at:

# http://$HOST/rpc/api/system/list_packages/

# This will probably be a pretty long list.

my $packages = $client->call(’system.list_packages’, $session, $systemid);

for my $package (@$packages) {

print Dumper($package);

}

# Additional system calls are described at:
