logparse

Logparse is a shell script that parses Caddy JSON log files and outputs them as formatted text. It supports the Common Log Format and Combined Log Format, usually used by traditional HTTP servers like Apache, however it is easy to customise the output using the --selector option.

The config file allows for changing default output format, add additional selectors and adapt logparse to other JSON sources. Logparse uses the powerful jq tool to process the JSON files.

Requirements

• Bash 5.1: Logparse is using associative arrays which is not available in plain POSIX shell scripts.
• jq 1.7: Tested with jq 1.7.1.
