Log management method and system of memory system

Abstract

The invention discloses a log management method and system of a memory system. The method comprises steps as follows: log information generated in the memory system is acquired in real time; the log information is analyzed, and the priority of each log in the log information is acquired; when the memory capacity of historical log information in the memory system exceeds the preset threshold value, historical logs are covered sequentially according to the low-to-high sequence of the priority of the historical logs. When a large amount of log information is covered with the provided log management method, the historical logs are covered sequentially according to the low-to-high sequence of the priority of the historical logs with a step-by-step coverage strategy, the most valuable log information is reserved, loss of important information because of log coverage is avoided, the logs are effectively managed, the stability, the reliability and the performance of the memory system can be accurately and effectively analyzed on the basis of log data, and the memory performance cannot be affected.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a log management method and system of a storage system. Background technique [0002] With the advancement of science and technology, the era of big data is gradually approaching, and the application of storage systems is becoming more and more extensive. In the storage system, a large amount of log data will be generated when the application software is running. These log data play a vital role in analyzing the stability, reliability and performance of the storage system, and log analysis is also the main means to solve the failure of the storage system. [0003] At present, the generation of logs in the storage system can be divided into two situations: one is that only a small number of error messages are output in the logs, which has little impact on storage performance, but the stability and reliability of the storage system cannot be analyzed based on the log data and...

[0003] At present, the generation of logs in the storage system can be divided into two situations: one is that only a small number of error messages are output in the logs, which has little impact on storage performance, but the stability and reliability of the storage system cannot be analyzed based on the log data and performance; the other is to output as comprehensive data information as possible in the log, but due to the limited storage space, when the log reaches a certain size, it can only cover the logs generated earlier, and some repeated log data It may overwrite the more important log data before, thus affecting the accuracy and comprehensiveness of log analysis
