Apache Log Format Reference
Common Log Format (CLF)
`%h %l %u %t \"%r\" %>s %b` captures remote host, identity, user, request timestamp, HTTP request line, status code, and response size.
Combined Log Format
Extends CLF by appending Referer (`%{Referer}i`) and User-Agent (`%{User-agent}i`) headers for complete traffic profiling.
HTTP Status Codes
Review HTTP status numbers (e.g., 200 OK, 304 Not Modified, 401 Unauthorized, 500 Server Error) directly in parsed logs.
Frequently Asked Questions (FAQ)
A standard regex pattern is: `^(\S+)\s+(\S+)\s+(\S+)\s+\[([^\]]+)\]\s+"([A-Z]+)\s+([^\s"]+)\s+([^"]+)"\s+(\d+)\s+(\S+)(?:\s+"([^"]*)"\s+"([^"]*)")?$`
You can modify or define custom log formats inside your `httpd.conf` or `apache2.conf` file using the `LogFormat` directive followed by a unique nickname.
