cause analysis排查Redis根本原因分析（redisroot）

Along with the development of the modern Internet industry, Redis plays a vital role in its architecture design. In the production process, Redis may sometimes malfunction, and we need to spend time in fixing it. Now, let s look at the cause analysis of Redis.

The specific method for the cause analysis of Redis is as follow:

1. Analyze logs

The log files of Redis are generally stored in the /var/logs/redis/ directory. You can open this directory to view the log files, such as redis_error.log and redis.log. After examining the logs, we can roughly identify the reason.

2. Test the commands manually

We can use the redis-cli tool to connect to our Redis instance and test out the commands manually. We can use basic commands such as Set , Get , Del , etc., to check for any abnormal results and get closer to the cause of the issue.

3. Use profiling tools

We can even use the profiling commands provided by Redis to detect the source of the problem. These commands can help us find out Redis’s memory usage, execution time of commands and IO status. The commands like “ INFO CPU ” and “ INFO MEMORY ” are some of the commands which are enough to give us a snapshot view of our redis instance.

To conclude, Redis cause analysis is a crucial step to ensure the performance of the production environment. By logging in the Redis instances, analyzing the logs, testing the commands manually and using the profiling tools, we can locate and correct the issues.
