我遇到了一个问题。我有两个不同的harpxoyLinux 服务器（位于不同的网络范围内）。在其中一个服务器上，我可以看到日志文件中生成了日志，但在另一台服务器上，日志文件中没有生成日志。
我比较了两台服务器的几乎所有可能的配置文件，它们看起来相同，但仍然找不到问题的线索。
Working服务器 -

这些文件在两个服务器上都是相同的
both are same
/usr/lib/systemd/system/rsyslog.service
/usr/lib/systemd/system/haproxy.service
/etc/sysconfig/haproxy
/etc/sysconfig/rsyslog
/etc/logrotate.d/haproxy
两者都有rsyslog-8.24.0-57.el7_9.1.x86_64和haproxy-1.5.18-9.el7_9.1.x86_64包装。
两台服务器上的配置几乎相同，但在非工作服务器上，日志不会进入其自己的日志文件。
有人可以帮忙吗？
谢谢，

在前端部分下添加以下行后，日志现在在日志文件中生成。
log 127.0.0.1:514 local0 debug
