Rsyslog过滤

Question

如何将不同的应用程序/服务日志消息从一台服务器转发到中央rsyslog服务器？需要说明的是: server1: swift (all in one) server2:Rsyslog快速日志位置:/var/ log /swift/all/ log (server1) sshd日志位置:/var/log/secure(Server1)

我想把swift和sshd日志存储在不同位置的server2中，问题是server2在不同位置记录日志，但这两个位置都在存储来自all.log和secure的日志!！我如何过滤这个？

这是server1(swift) rsyslog.conf

当您通过imfile从文件中读取消息时，您将分配标签(分别为swift-log和sshd )。您可以在接收服务器上使用这些标记进行过滤。类似于：

if $syslogtag == "sshd" then {
  action(type="omfile" file="/var/log/secure"
} else if $syslogtag == "swift-log" then {
  action(type="omfile" file="/var/log/swift
}

或者，您也可以更改imfile配置，为尾部文件(比如local6和local7)分配不同的工具。然后，您可以使用BSD样式的配置来进行过滤，如下所示：

local6.* /var/log/secure # assuming local6 is assigned to sshd logs
local7.* /var/log/swift  # and local7 for swift logs

尽管对于某些事情，你可能需要升级到rsyslog的最新版本(例如，8.13是现在的最新版本，但许多发行版仍然带有5.x)。你可以在这里找到流行发行版的软件包：http://www.rsyslog.com/downloads/download-other/
