How to use logs to check problems and deal with them in mall development

Logs refer to information generated by some systems or applications when they are running, and can be used to track error conditions and debug applications. In mall development, logs are very important. They can record user behavior and the execution process of back-end programs to help developers monitor and maintain the system, identify possible problems and solve them in a timely manner.

The following will introduce how to use logs to check problems and deal with them in mall development:

1. Record logs

In mall development, recording logs needs to determine which aspects need to be monitored. and logging, and set the logging level for each aspect. For example, for the user login process, the following levels can be recorded:

1. DEBUG: Record the details of all login processes, such as user name, IP address, login time, etc.
2. INFO: Record the overall situation of login success and failure, such as the number and proportion of success/failure, etc.
3. WARN: Record abnormal events, such as entering an incorrect username or password.
4. ERROR: Log serious error events, such as failure to connect to the database or security breach.

2. Analysis logs

In mall development, analyzing logs can help you understand system operation, diagnose errors, optimize applications and other issues. You can analyze the logs through the following steps:

1. Collect the logs to the central log server and perform statistics and analysis through the visual interface.
2. Use the query tool to analyze errors and exceptions when the application is running, and find the problematic lines, functions or modules.
3. Optimize application performance and user experience based on statistical analysis results.

3. Processing logs

In mall development, the purpose of processing logs is to solve problems and reduce the risk of problems. The following are common processing methods in mall development:

1. For known problems, you can write code based on the results of log analysis to solve the problem.
2. For unknown problems, it is necessary to locate the problem based on the log analysis results, and research and test the logs to better understand the root cause of the problem.
3. For the root cause of the problem, you can fix the problem and prevent it from happening again by modifying the code, updating plug-ins, reconfiguring the server, and patching.

In mall development, log recording, analysis and processing are important components to ensure system reliability and stability. The above is how to use logs to check problems and deal with them in mall development. I hope it will be helpful to your development work.
