   本人公司的应用是把log4j的日志通过syslog-ng client 发送到server端，然后通过python脚本分析写入数据库。然后再通过open flash chart画出图表出来，不多说了直接贴安装方法和具体的配置。
                    
pre-acquire
eventlog-0.2.5.tar.gz
libnet
glib-java.x86_64
glib-java-devel.x86_64
glib2-devel


step 1:install  syslog-ng

tar xzvf syslog-ng-2.0.7.tar.gz
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
./configure --prefix=/usr/local/syslogng --enable-tcp-wrapper  --sysconfdir=/etc
make && make install

step 2:initiate

1:create syslog-ng.conf in /etc/ directory
2:create service lsb script in /etc/init.d directory
cp init.d.RedHat-7.3 /etc/init.d/syslogng and modify PATH   environment

3:create logs group and logs user


step 3:configuration

# logging to central loghost. Listens only on localhost interface;
# requires "logs" user and group on system.
#
# Local logs are stored under /var/log/archive in a syslog-ng specific
# format that includes facility, priority, and a timestamp that includes
# the year.
