HAProxy 统计页面说明

Question

在前端部分下的 HAProxy 统计页面中，Errors - Req 是什么意思？

Errors             |
Req   | Conn | Resp
31 758|      |

Answer 1

从 documentation 开始，此值映射到 CSV 统计信息页面中的 ereq 列，含义如下：

12. ereq [LF..]: request errors. Some of the possible causes are:
    • early termination from the client, before the request has been sent.
    • read error from the client
    • client timeout
    • client closed connection
    • various bad requests from the client.
    • request was tarpitted.
