我正在尝试捕获日志中每个请求的唯一 ID。我以为我可以capture request header X-Unique-ID len 16
在标头上使用,但它不起作用。有什么建议吗?

要记录唯一 ID,您需要创建使用 %ID 标签的自定义日志格式。无需使用“捕获请求标头”来记录该格式。
使用自定义日志格式重写上面的示例:
frontend http-in
bind *:8080
monitor-uri /haproxy-health
unique-id-header X-Unique-ID
unique-id-format %{+X}o\ %ci:%cp_%fi:%fp_%Ts_%rt:%pid
capture request header Host len 32
capture request header User-Agent len 200
rspidel ^X-Powered-By:.*
log-format %{+Q}r\ %ST\ "%CC"\ "%hr"\ "%CS"\ "%hs"\ %ID
通过这样的配置,您将获得类似这样的日志消息:
Sep 10 17:37:55 lb2 haproxy[28497]: "GET /favicon.ico HTTP/1.1" 200 "-" "{172.20.0.20:8999|Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.85 Safari/537.36}" "-" "" AC140001:C1B8_AC140014:2327_55F1BFF3_0003:6F51
最后一个条目是唯一的 ID。
