Process monitoring method for database system and comprehensive monitoring system for rail transit

Abstract

The present invention discloses a process monitoring method for a database system, which is applied to a comprehensive monitoring system for rail transit. The method comprises: acquiring first timestamp information of a service process; if the first timestamp information is not received within a first preset duration, marking the service process as an abnormal service process, and performing statistics on a frequency value of occurrence of the abnormality of the abnormal service process within a second preset duration, wherein the second preset duration is greater than the first preset duration; and if the frequency value is greater than or equal to the preset abnormal threshold, marking the abnormal service process as a fault, no longer restarting the service process in the system, and generating alarm information. According to the technical scheme of the present invention, by monitoring the continuous abnormal service process, the waste of resources is avoided, and the continuous abnormal service process is alerted to the operation and maintenance personnel, so that the reliability of the system is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of rail transit monitoring, and in particular to a process monitoring method of a database system and a comprehensive traffic monitoring system. Background technique [0002] The rail transit comprehensive monitoring system undertakes the major task of monitoring the urban rail transit control center and station power, environmental control, signal, fire alarm and other subsystem equipment. It is the basic guarantee for the normal operation of the subway and disaster relief command, involving personal and Equipment Security. Therefore, the integrated monitoring system has extremely high requirements for reliability and safety. [0003] The real-time database system that undertakes the core function in the integrated monitoring system usually monitors the operation of the entire system through the process monitoring program, so that when some processes of the system are abnormal, op...

Problems solved by technology

In the prior art, the process monitoring logic in the real-time database system is to start a thread separately, which is responsible for the regular detection of the system process. If any process is found to have timed out and the timestamp is not updated, the process is considered abnormal, and then it is checked whether
