How to analyze Golang logs on Debian

This article guides you how to effectively analyze Golang application logs on Debian systems.

Step 1: Confirm log generation

First, make sure your Golang app is correctly configured with logging. Most Golang applications use built-in log packages or third-party libraries such as logrus or zap to generate logs. Please check your code to make sure the log is written to the file correctly.

Step 2: Locate the log file

Golang applications typically store log files in their working directory, but the location depends on your configuration. Please check the application's configuration file or code to determine the log file path.

Step 3: View log files

You can view log files using a text editor or command line tool such as cat , tail , less . For example, look at a log file named log.txt :

 cat log.txt # View the entire file tail -f log.txt # View log updates in real time

Step 4: Log Analysis

Carefully check the log content for errors, warnings, or other exceptional information. Use the grep command to search for specific keywords, for example:

 grep "ERROR" log.txt # Search for rows containing "ERROR"

Step 5: Advanced Analytical Tools

For large log files, text processing tools such as awk , sed , and perl can help you extract and analyze specific information.

Step 6: Problem Solving

Based on the analysis results, find out the application problems and take corresponding measures to fix them.

Step 7: Professional log management tool

For more powerful log analysis capabilities, it is recommended to use professional log management tools such as ELK Stack (Elasticsearch, Logstash, Kibana) or Graylog, which can help you collect, search, analyze and visualize log data.

The above steps are applicable to Golang application log analysis on Debian systems. Depending on the actual situation, you may need to adjust these steps.
