Abstract

In a data processing system comprising a plurality of systems each including a plurality of console type typewriters for establishing communications pertaining to data processing operations between an operator and the system, the communication information which is entered into and derived from a central processing unit in each system by the console type typewriter is stored in a character buffer unit corresponding to the console type typewriter in a monitor transfer control unit, and a buffer scanning unit scans the character buffers to transfer the contents therein into a statistical analyzer or processing unit so that communication information may be automatically analyzed and summarized to obtain the data per day or month required for determining whether or not the data processing system has been effectively operated.

Claims

1. A system for monitoring the operation of a data processing system comprising

(A) a plurality of data processing systems each comprising

(a) a central processing unit,

(b) a plurality of console type typewriters connected through a data transfer unit to said central processing unit for transferring communication information to and from said central processing unit,

(c) a plurality of remote terminals connected to said central processing unit through a communication control equipment, and

(d) a console terminal system supervisor and control unit connected to said data transfer unit for supervising and controlling each of said plurality of data processing systems;

(B) a monitor transfer control unit comprising

(a) a plurality of character buffer units respectively connected to said plurality of console type typewriters, and

(b) a buffer scanning unit for sequentially scanning said character buffer units; and

(C) a statistical analyzer connected to said buffer scanning unit for receiving the communication information from said monitor transfer control unit, analyzing the received communication information and automatically summarizing the data required for effective and efficient utilization of said data processing systems.

2. A system as set forth in claim 1 wherein said monitor transfer control unit further comprises

(a) a buffer switching unit connected to said console terminal system supervisor and control unit through a system-supervisor-and-control-unit adapter unit,

said buffer switching unit being responsive to a console-type-typewriter designation instruction transmitted from said system supervisor and control unit for selecting a designated character buffer unit and connecting the same to said adapter unit.

3. A system as set forth in claim 1 wherein said monitor transfer control unit further comprises a buffer switching unit connected to said communication control equipment

through a remote-terminal-equipment adapter unit, said buffer switching unit being responsive to a console-type-typewriter designation instruction transmitted from the remote terminal equipment for selecting the character buffer unit corresponding to the designated console type typewriter and connecting said character buffer unit to said adapter unit.

5. A system as set forth in claim 1 wherein said monitor transfer control unit further comprises

a remote-terminal-equipment adapter for normally interconnecting between said communication control equipment and a specific remote terminal equipment.

4. A system for monitoring the operation of a data processing systemcomprising

(A) a plurality of data processing systems each comprising

(a) a central processing unit,

(b) a plurality of console type typewriters connected through a data transfer unit to said central processing unit for transferring communication information to and from said central processing unit,

(c) a plurality of remote terminals connected to said central processing unit through a communication control equipment, and

(d) a console terminal systemmm supervisor and control unit connected to said data transfer unit for supervising and controlling each of said plurality of data processing systems;

(B) a monitor transfer control unit comprising

(a) a plurality of character buffer units respectively connected to said plurality of console type typewriters,

(b) a buffer scanning unit for sequentially scanning said character buffer units, and

(c) a first adapter unit for transmitting the output from said buffer scanning unit;

(C) a statistical analyzer connected to said buffer scanning unit through said first adapter unit for receiving communication information from said first adapter unit, analyzing the received communication information and automatically summarizing the data required for the effective operation control of said data processing systems;

(D) a first buffer switching unit responsive to a first consoletype-typewriter designation instruction transmitted from said console terminal system supervisor and control unit for connecting said system supervisor and control unit to the character buffer unit designated by said first instruction through a second adapter unit; and

(E) a second buffer switching unit responsive to a second console type typewriter designation instruction transmitted from the remote terminal equipment for connecting said remote terminal equipment to the character buffer unit designated by said second instruction through a third adapter unit.
