Cacti插件syslog使用Syslog-ng收集日志

在Cacti上安装好syslog插件

安装开发版本的Syslog-ng安装YUM源：

Centos 6:

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

rpm -Uvh epel-release-latest-6.noarch.rpm
Centos 7:

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

rpm -Uvh epel-release-latest-7.noarch.rpm

安装Syslog-ng及相关组件：

@version:3.15
@include "scl.conf"

# syslog-ng configuration file.
#
# This should behave pretty much like the original syslog on RedHat. But
# it could be configured a lot smarter.
#
# See syslog-ng(8) and syslog-ng.conf(5) for more information.
#
# Note: it also sources additional configuration files (*.conf)
#       located in /etc/syslog-ng/conf.d/
