| |
| =head2 load |
| |
| Parameters : none |
| Returns : boolean |
| Description : Checks if the lab computer is responding to SSH. If so, true is |
| returned indicating the lab computer is ready to be reserved for |
| a user. If it is not responding, false is returned. This should |
| fail the request before the Connect button is presented to the |
| user. |

| |
| sub load { |
| my $self = shift; |
| if (ref($self) !~ /VCL::Module/i) { |
| notify($ERRORS{'CRITICAL'}, 0, "subroutine was called as a function, it must be called as a class method"); |
| return; |
| } |
| |
| my $request_id = $self->data->get_request_id(); |
| my $request_check_time = $self->data->get_request_check_time(); |

| } |

| #////////////////////////////////////////////////////////////////////////////// |
| |
| =head2 node_status |
| |
| Parameters : none |
| Returns : 'READY' or 'RELOAD' |
| Description : Checks if the lab computer is responding to SSH. If so, 'READY' |
| is returned. This prevents the need to call load(). If the |
| computer is not responding, 'RELOAD' is returned which will |
| result in load() being called. |
