This integration periodically fetches metrics from Apache servers. It can parse access and error logs created by the Apache server.

Compatibility

The Apache datasets were tested with Apache 2.4.12 and 2.4.46 and are expected to work with all versions >= 2.2.31 and >= 2.4.16 (independent from operating system).

      %h %l %u %t \"%r\" %>s %b

    • Example:

      127.0.0.1 user-identifier frank [10/Oct/2000:13:55:36 -0700] "GET /apache_pb.gif HTTP/1.0" 200 2326

  • Combined Log Format

    • The combined LogFormat can be used as follows:

      I. %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"

      II. %A:%p %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"

      III. %h:%p %l %u %t \"%{req}i %U %H\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"

    • Example:
