如何通过unix sock将haproxy信息日志发送到rsyslog？

编程问答 2022-06-01

问题描述

嗨，我正在尝试配置 haproxy/rsyslog，以便只有 haproxy info 日志通过 unix sock 发送到 ryslog。

这是我的配置：

haproxy 配置

frontend MY_FRONT_END
    log 127.0.0.1 /var/log/haproxy/dev/log info
    bind *:12080
    default_backend HTTP_BACKEND

rsyslog 配置

$ModLoad imuxsock
$InputUnixListenSocketCreatePath on
$InputUnixListenSocketHostName localhost
$AddUnixListenSocket /var/log/haproxy/dev/log
*.info /var/log/haproxy/access.log

然而，我在日志中看到的不仅仅是 haproxy 日志，日志包含所有与 haproxy 无关的信息（前三个日志行）

我如何配置以实现此目的（仅通过 unix sock 将 haproxy 信息日志发送到 rsyslog）？
