Embodiment Construction

[0054] figure 1 It is a figure showing the operation environment of a system event log system (system event log system). The monitoring target program 104 and the non-monitoring target program 105 acquire and operate a system event generated by a user's keyboard or mouse operation through API calls. The recorder unit 101 acquires these system events from the event queue 107 in the operating system 106 by means of a global hook, selects only predetermined events among events occurring during the operation of the monitoring target program 104, and saves them in a log file. in the storage unit 102. In addition, it operates so that a real-time screen image is acquired and stored in the screen image file storage unit 103 .

[0055] The log file storage unit 102 and the screen image file storage unit 103 are provided, for example, in a storage area of ​​a hard disk drive. In addition, the recorder unit 101 , the monitoring target program 104 , and the non-monitoring target progra...

Abstract

Provided is a system event logging system for recoding a log of system events which relate to a process being monitored, the logging system having the aim of selectively recording system events that are necessary for purposes such as the reproduction of operations and excluding system events that are outside the intended purpose. Flag conditions and flag operation instructions are provided for each of the filters in a filter list (702), and the system event logging system uses the flag conditions as the conditions for applying the filters. When applying the filters, the logging system operates the flags according to the flag operation instructions. Thus, interrelated operation between the filters can be achieved by means of the flags, and also, interrelated operation can be achieved by means of the flags even between the processes performed for the system events.

Description

technical field [0001] The present invention relates to a system event log system for recording system event logs related to monitoring target processes. Background technique [0002] Patent Document 1 ("Computer System and Application Program Operation Reproduction Method") discloses a computer system and application program operation reproduction method, in which the application program does not need to be provided with a redundant load for state reproduction, and the application Abnormal end of the program can correctly reproduce the state of the application program according to the operation at the time of abnormal end, and can significantly reduce the operation burden and operation time caused by the state reproduction operation. [0003] Specifically, operation logging is used for operation reproduction. [0004] When a log of a system event is recorded as an operation record, many unnecessary logs are included, and it may become difficult to reproduce an operation fr...
