Several commonly used free website server log analysis software tools

When we normally perform server and website operation and maintenance, if there is a failure or we analyze the behavior of search engines or website visitors, sometimes we analyze it through statistical tools, but for some advanced usage, we directly log the server logs analyze. Server log analysis software tools are needed here. There are many log analysis software currently available. Which one do we all use?

Server log analysis software or online tools all export or generate LOG log files online based on our commonly used WEB environment, and then conduct visual data analysis. It will distinguish each time node, the behavior of visitors and crawlers. Some basic users may just look at the LOG log file when needed. If you analyze it in depth, you will need an auxiliary log analysis tool.

First, Webalizer

Webalizer, written in C language, has high operating efficiency and can analyze 10,000 data records per second. Someone has tested it, and it only takes more than ten seconds to analyze a 40M log file. Webalizer log tool is an efficient, free web server log analysis program.

Webalizer log tool will save the analysis results in HTML file format, which can be easily browsed through the web. Webalizer supports the standard common log file format (Common Logfile Format).

Second, GoAccess

GoAccess, a free and open source tool from abroad that can be deployed on the server to implement real-time log analysis. Moreover, GoAccess log analysis can realize real-time visual WEB display. This excellent interactive function is more user-friendly than some mere data display. GoAccess can implement HTML, CSV, and JSON reports on the WEB browser side, and is more suitable for projects that need to strengthen operation and maintenance capabilities and data analysis.

GoAccess is written in C language, can achieve millisecond-level updates, and supports WEB log formats such as Apache, Nginx, Amazon S3, Elastic Load Balancing, CloudFront, etc. Can implement beautiful terminal and bootstrap style control panel. In this article, the author will explore the deployment and functions of GoAccess logging software with everyone. (Function introduction)

Third, Analog

Analog is also an open source log analysis tool used to quickly process logs. It is also very efficient, but the log results generated by this tool are not beautiful enough. Analog can read gz format compressed log files and supports reading multiple files. After downloading and installing Analog and making necessary configurations, you can run analog directly. You can also specify corresponding startup parameters to change the content blocks of the output file. Generally, crontab is used to set a specified time to run the program.

Fourth, LOGalyze

LOGalyze, a user-oriented open source server log and monitoring log tool from abroad. Supports Windows and Linux systems, can be used to collect data and then search for the program to find the required information. Generally, this tool is used a lot abroad, but it doesn’t seem to be very suitable for the usage habits of our mainland Chinese users.

The LOGalyze configuration process is also slightly more complicated, and then we run dynamic reports in LOGalyze's web interface and export them to Excel files, PDF files, or other formats. These report results are based on multi-dimensional statistics managed by the LOGalyze backend.

Fifth, Papertrail

Papertrail is a log analysis software tool for Windows systems. The software can support automatic scanning of log data. When Papertrail scans log data, you can choose what information you want the scan results to display. For example, you can choose to scan for IP addresses, email addresses, GUID/UUIDs, HTTP(s) URLs, domains, hosts, filenames and reference text, etc.

To summarize, most of us webmasters rarely analyze logs on a daily basis. Even if they need to be used, they only look at them when a failure occurs. However, there are currently some WEB environments that come with built-in plug-ins that support available log analysis. For example, they will look at search engine crawler logs and user behavior logs.
