Optimizing Caddy logs for Goaccess

I recently discovered Goaccess, a simple tool that generates analytics reports from web server logs.

The more information the log file contains, the better the report is. The default log format of Caddy does not record virtual hosts, user agent, referer and latency so they need to be added explicitly:

log / /var/log/caddy/access.log "{hostonly} {combined} {latency_ms}"

Goaccess can then use this extra information with:

goaccess access.log -o goaccess.html --log-format='%v %h %^[%d:%t %^] "%r" %s %b "%R" "%u" %L' --time-format='%H:%M:%S' --date-format='%d/%b/%Y'
