The Ngxtop utility monitors access-logs and outputs them to the console in the style of the famous [tor] program (https://fornex.com/help/top-command/)

    The installation is done as follows:

    # pip install ngxtop
    

    Syntax for using the utility:

    ngxtop [options]  
    ngxtop [options] (print|top|avg|sum)  
    

    You can see a list of all available options with the command:

    # ngxtop --help
    

    By default, Ngxtop detects the location of the Nginx access-log by itself from the configuration file /etc/nginx/nginx.conf. If there are several such logs, you will need to choose which one to work with:

    # ngxtop
    Multiple access logs detected in configuration:  
    1. /var/log/nginx/access502.log  
    2. /var/log/nginx/access.api.log  
    3. /var/log/nginx/access.img.log  
    4. /var/log/nginx/access.log  
    5. /var/log/nginx/access404.log  
    

    To see requests with a 404 status, you can use the command:

    # ngxtop -i 'status == 404' print request status
    

    result of execution:

    running for 130 seconds, 150 records processed: 1.15 req/sec  
    
    request, status:
