In this issue, the editor will bring you about the statistical script of python log analysis. The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.

The script is similar to the tail function of shell. It is used to count the number of status codes of 4xx and 5xx per minute, the number of php execution time less than 1 second, 1-5 seconds, and more than 5 seconds, and the concurrent requests per second. Put the results in the / tmp directory, or you can draw the results with cacti.
