RHEL6.5安装collectd5.8 采集数据至logstash

下载collectd5.8

https://storage.googleapis.com/collectd-tarballs/collectd-5.8.0.tar.bz2

安装

https://collectd.org/download.shtml

tar xf collectd-version.tar.bz2
cd collectd-version
./configure
make all install

复制启动脚本

cp /usr/local/collectd-5.8.0/contrib/redhat/init.d-collectd  /etc/init.d/
chmod +x /etc/init.d/init.d-collectd 
修改启动脚本配置文件地方

修改后的启动脚本用##标识主语路径

修改collectd


[root@znhjkapp02 ~]# grep -v ^# /opt/collectd/etc/collectd.conf |grep -v ^$
Hostname    "znhjkapp02"
LoadPlugin syslog
LoadPlugin cpu
LoadPlugin interface
LoadPlugin load
LoadPlugin memory
LoadPlugin network
<Plugin network>
	<Server "9.1.8.247" "25826">  #collectd收集来数据传送给logstash的服务器地址
	</Server>
</Plugin>

启动并查看日志没错就OK

[root@znhjkapp02 ~]# /etc/init.d/init.d-collectd start
collectdmon (pid  1034) 正在运行...
查看日志

logstash 安装用rpm

[root@znhjkapp02 ~]# cat /etc/logstash/conf.d/collectd.conf
input{
 udp {
    port => 25826
    buffer_size => 1452
    workers => 3          # Default is 2
    queue_size => 30000   # Default is 2000
    codec => collectd { }
    type => "collectd"
}
}
output {
  elasticsearch {
    hosts => '9.1.8.234'
    index => "logstash-collectd-%{+YYYY.MM.dd}"
       }
        stdout { codec => rubydebug }
}

会启动一个udp的25826端口监听来自collectd的数据
