     VMRSM is a real-time system performance monitor that accurately evaluates the                         
     current state of the VM system keeping your technical support staff ever                       
     aware of the changing resource demand and load placed upon the VM system.                      
     The important CP and Guest statistics are clearly and graphically reported                              
     upon.  You are alerted to exceptional performance conditions as they occur                          
     not minutes or hours later.                                                     
                                                                                                    
     VMRSM provides your Systems Programmer with a viewport to the VM System                        
     operation from any supported local, SNA or Internet connected terminal.                      
     VMRSM permits VM performance problems to be examined directly and allow                        
     the Systems Programmer to see the differences immediately as he/she makes                      
     adjustments to the environment.  Categories of measurment include:                                                                
 
                General monitoring of the overall VM/ESA system,
                Specific Virtual Machine monitors,
                I/O distribution,
                Real Device monitoring,
                Active Users monitoring.
                                                                                                    
     Performance management begins with knowing precisely the current running                       
     condition and resource consumption of your systems.                                            
 
     Most of the displayed statistics are self-explanatory, but further
     interpretation can be found detailed in the IBM manual:
     'VM/ESA CP Data Areas and Control Blocks Logic'. 
     VMRSM extracts its data directly from the resident portions of the
     VM System Control Program.   Displays are presented in full screen and
     refreshment is timed automatic.
