1、安装与启动collectd命令：sudoapt-get install collectd
sudo /etc/init.d/collectd start（这样，就启动了collectddeamon程序）
2、部署 collectd
两台ubuntu虚拟机，一台为server，一台client。server IP:202.194.68.152，拟接收数据端口25827.
server安装，版本为collectd 4.10.1
命令：apt-get install collectd
/etc/collectd/collectd.conf配置(主要加入network plugin和rrdtool plugin)：
LoadPlugin syslog
<Plugin syslog>
LogLevel info
</Plugin>
LoadPlugin cpu
LoadPlugin df
LoadPlugin disk
LoadPlugin interface
LoadPlugin load
LoadPlugin memory
LoadPlugin network
LoadPlugin rrdtool
<Plugin network>
# # client setup:
# Server "ff18::efc0:4a42" "25826"
# <Server "239.192.74.66" "25826">
# SecurityLevel Encrypt
# Username "user"
# Password "secret"
# Interface "eth0"
# </Server>
# TimeToLive "128"
#
# # server setup:
Listen "202.194.68.152" "25827"
# <Listen "202.194.68.152" "25827">
# SecurityLevel Sign
# AuthFile "/etc/collectd/passwd"
# Interface "eth0"
# </Listen>
# MaxPacketSize 1024
#
# # proxy setup (client and server as above):
# Forward true
#
# # statistics about the network plugin itself
# ReportStats false
#
# # "garbage collection"
# CacheFlush 1800
</Plugin>
<Plugin rrdtool>
DataDir "/var/lib/collectd/rrd"
#CacheTimeout 120
#CacheFlush 900
#WritesPerSecond 30
#RandomTimeout 0
#
# The following settings are rather advanced
# and should usually not be touched:
#StepSize 10
#HeartBeat 20
#RRARows 1200
#RRATimespan 158112000
#XFF 0.1
</Plugin>
配置好保存启动：/etc/init.d/collectd start
client端配置：
安装：apt-get install collectd
同样在/etc/collectd/collectd.conf下配置：
不同的是在network插件里，配置
<Plugin network>
## client setup:
#Server "202.194.68.152" "25827"
#<Server "202.194.68.152" "25827">
#SecurityLevel Encrypt
#Username "user"
#Password "secret"
#Interface "eth0"
#</Server>
#TimeToLive "128"
#
## server setup:
#Listen "ff18::efc0:4a42" "25826"
#<Listen "239.192.74.66" "25826">
#SecurityLevel Sign
#AuthFile "/etc/collectd/passwd"
#Interface "eth0"
#</Listen>
#MaxPacketSize 1024
#
## proxy setup (client and server as above):
#Forward true
#
## statistics about the network plugin itself
#ReportStats false
#
## "garbage collection"
#CacheFlush 1800
</Plugin>
配置好后重启，/etc/init.d/collectd start
在server端，用rrdtool查看数据。
