Abstract

In order to monitor the interface between the customer and a data processing system, it is desirable to record of all machine interruptions whether caused by defects in hardware, software or operational characteristics of the system. Information as to recovery time, frequency of interruptions and corrective measures employed are important in planning future systems. This information is obtained via an operational activity recorder. This provides a magnetic tape record of all entries into and printouts from the console typewriter associated with a system. In addition, it also records selected operation conditions and identifies the time of occurrence of all recordings. Information from typewriter 1 is provided by reed switches 2 mounted in close proximity to control magnets 3 in the typewriter.

Operational Activity Recorder

In order to monitor the interface between the customer and a data processing system, it is desirable to record of all machine interruptions whether caused by defects in hardware, software or operational characteristics of the system. Information as to recovery time, frequency of interruptions and corrective measures employed are important in planning future systems. This information is obtained via an operational activity recorder. This provides a magnetic tape record of all entries into and printouts from the console typewriter associated with a system. In addition, it also records selected operation conditions and identifies the time of occurrence of all recordings. Information from typewriter 1 is provided by reed switches 2 mounted in close proximity to control magnets 3 in the typewriter. Energization of magnets 3 closes the contacts of switches 2 providing signals at logic and control unit 4.

This unit includes a plurality of Nand's which convert the applied switch 2 signals to a six-bit BCD code for application to tape recorder 5. Manual entry switches are also provided in unit 4 to enter into recorder 5 data which identifies the customer and related equipment. In addition, a timing device consisting of a trigger ring, driven from a one pulse per second source, is contained within unit 4 to indicate the times at which entries and printouts occur.
