haproxy_log_parser is a gem that parses logs in HAProxy's HTTP log format.
Use HAProxyLogParser.parse to parse a line; this will return an
HAProxyLogParser::Entry for normal lines and HAProxyLogParser::ErrorEntry
for connection error lines.
Example:
require 'haproxy_log_parser'
result = HAProxyLogParser.parse('Aug 9 20:30:46 localhost haproxy[2022]: 10.0.8.2:34028 [09/Aug/2011:20:30:46.429] proxy-out proxy-out/cache1 1/0/2/126/+128 301 +223 - - ---- 617/523/336/168/0 0/0 {www.sytadin.equipement.gouv.fr||http://trafic.1wt.eu/} {Apache|230|||true} "GET /index.html HTTP/1.1"')
result.client_ip # => "10.0.8.2"
result.captured_response_headers # => ["Apache", "230", "", "", "true"]
