Embodiment Construction

[0042] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] For instantaneous monitoring objects such as locks, blocking, and database server loads in the database, the embodiment of the present invention adopts a multi-check method. If the monitoring objects exceed the corresponding threshold for multiple consecutive times, an alarm message will be sent to notify the database Management personnel, thereby reducing the number of false alarms, improving the accuracy of the alarm, and providing a strong guarantee for the safe operation of the database.

[0044] Wherein, the concept of the lock means that in order to prevent the object from being modified by two different users at the same time, the database creates a data structure called a lock to implement the locking mechanism. Thi...

Abstract

The invention discloses a database monitoring method and a device for solving the problems that the traditional database monitoring method has more false positives and low alarm accuracy rate for instantaneous monitoring objects. The method comprises: a marker bit is arranged on each monitoring object which needs double checks for marking whether collected data exceeds thresholds or not; the data of the monitoring objects is regularly collected and compared with the corresponding thresholds; corresponding marker bit is read when in need of double checks if the data exceeds the threshold, whether the data collected at the last time exceeds the threshold or not is judged according to the marker bit, if yes, an alarm message is emitted; and then the current comparison result is upgraded to the marker bit, wherein, the number of checks is defined according to the frequency of data collection. In the invention, the alarm message is emitted only when the monitoring object continuously exceeds the corresponding threshold for a plurality of times, thereby reducing the number of false positives, improving the accuracy rate of alarm, and providing a strong guarantee for the safe operation of a database.

Description

technical field [0001] The invention relates to database technology, in particular to a database monitoring method and device. Background technique [0002] In various business applications, the application system usually deploys a database to store and manage the data of the entire system, so it becomes very important to monitor the operation of the database system. For various database systems running on the operating system, the percentage of database table space usage, the size of disk sorting space usage, database operation, locks, blocking, and database server load are all common monitoring objects. [0003] For the above monitored objects, the traditional monitoring method is: set a corresponding threshold for each monitored object, and call the police immediately when the monitored data exceeds the threshold. For example, for the database table space utilization percentage, if the threshold value is set to 90%, it means that when the space utilization rate of a tabl...
