安裝collectd包操作同客戶端相同，不在贅述

修改network組件為本機監聽地址

安裝collectd-web插件

該插件是一個perl的CGIweb程序.在我們的http://172.17.47.160/download目錄有下載(注意該項目是修改了的，如果網絡上下載的源碼是不能解析libvirt的虛擬機的cpu使用率的)?修改的地方:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

collectd-web-master/cgi-bin/collection.modified.cgi ???????virt_vcpu => [ ????????????'-v', 'CPU load (%)', ????????????'-X', '0', ????????????'DEF:avg_1={file}:value:AVERAGE',?????????? ->:ns:AVERAGE ????????????'DEF:min_1={file}:value:MIN',?????????????? ->:ns:MIN ????????????'DEF:max_1={file}:value:MAX',?????????????? ->:ns:MAX ????????????'CDEF:avg=avg_1,10000000,/', ????????????'CDEF:min=min_1,10000000,/', ????????????'CDEF:max=max_1,10000000,/', ????????????"AREA:max#$HalfBlue", ????????????"AREA:min#$Canvas", ????????????"LINE1:avg#$FullBlue:Percent", ????????????'GPRINT:min:MIN:%6.2lf%% Min,', ????????????'GPRINT:avg:AVERAGE:%6.2lf%% Avg,', ????????????'GPRINT:max:MAX:%6.2lf%% Max,', ????????????'GPRINT:avg:LAST:%6.2lf%% Last\l' ????????],?? ????????virt_cpu_total => [ ????????????'-v', 'CPU load (%)', ????????????'-X', '0', ????????????'DEF:avg_1={file}:value:AVERAGE',??????? ->:ns:AVERAGE ????????????'DEF:min_1={file}:value:MIN',??????????? ->:ns:MIN ????????????'DEF:max_1={file}:value:MAX',??????????? ->:ns:MAX ????????????'CDEF:avg=avg_1,10000000,/', ????????????'CDEF:min=min_1,10000000,/', ????????????'CDEF:max=max_1,10000000,/', ????????????"AREA:max#$HalfBlue",

修改的原因是同rrd文件的文件結構有關系，使用

1	rrdtool info virt-vcpu-1.rrd

rrd文件存儲配置

1 2 3 4

mkdir /etc/collectd/ vi /etc/collectd/collection.conf 添加下列數據: datadir:"/data/openstack/rrd_store"

此配置是給collect-web使用的。 進入到collect-web目錄，啟動服務：

1	python runserver.py 172.17.46.4 8084
