Problems solved by technology

However, in today's distributed database, when computing and storage are distributed, users operate in different ways. Many experiences cannot be replicated in different user systems, and some experiences cannot be reused even by the same user in different quarters.
[0004] In addition, during the operation of distributed databases, the number of monitoring indicators increases sharply, and manual learning of indicators and threshold setting will become labor-intensive and time-consuming; at the same time, with the diversification of database business and seasonal time factors (for example: ), different types and periods of indicators have different re

Abstract

The invention particularly relates to a distributed database operation and maintenance dynamic threshold alarm method and device. According to the distributed database operation and maintenance dynamic threshold value alarm method and device, the method comprises the steps of firstly, establishing a threshold value model based on an extreme value theory, collecting and processing original information input of a database index model and converting into a threshold value model matching input format, and calibrating the threshold value model of each node; and comparing the real-time monitoring index data of each node with the calculated current threshold upper and lower limit constraints, and if the real-time monitoring index data exceeds the threshold upper and lower limit constraint range, generating an alarm and processing. According to the distributed database operation and maintenance dynamic threshold value alarm method and device, important indexes of the database can be monitored in real time, alarm information can be sent out for abnormal conditions of the indexes of the database in time, the threshold value can be updated in real time according to the change of the monitored indexes, the task load of manual monitoring is greatly reduced, the monitoring efficiency is improved, and normal operation of the database is ensured.
