OpenStack collectd的從零安裝服務端

安裝collectd包操作同客戶端相同，不在贅述

配置檔案

修改network元件為本機監聽地址

安裝collectd-web外掛

該外掛是一個perl的CGIweb程式.在我們的http://172.17.47.160/download目錄有下載(注意該專案是修改了的，如果網路上下載的原始碼是不能解析libvirt的虛擬機器的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檔案的檔案結構有關係，使用

1	rrdtool info virt-vcpu-1.rrd

rrd檔案儲存配置

1 2 3 4

mkdir /etc/collectd/ vi /etc/collectd/collection.conf 新增下列資料: 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
