如何使用 CPU 和 MEM 使用数据填充 RRD 数据库?
我有一个 Lighttpd 服务器(在 Centos 上),想要显示 4 个图表:lighttpd 流量、lighttpd 每秒请求数、CPU 使用率和 MEM 使用率。我已经为 lighttpd 配置设置了 rrd 数据库,如下所示:
rrdtool.binary = "/usr/bin/rrdtool"
rrdtool.db-name = "/var/www/lighttpd.rrd"
并将其放入我的 WWW cgi-bin sh 文件中,该文件从 lighttpd RRD 文件获取数据并创建每秒流量和请求的图表,如下所示:
#!/bin/sh
RRDTOOL=/usr/bin/rrdtool
OUTDIR=//var/www/graphs
INFILE=/var/www/lighttpd.rrd

基本上这不是我的脚本,我从互联网上的某个地方获取它。 现在我想对 CPU 使用率和 MEM 使用率做同样的事情。 我不喜欢使用任何额外的软件包!
正如您所看到的,lighttpd 使用流量数据和每秒请求数填充lighttpd.rrd 文件。现在我希望系统用 CPU 和 MEM 使用情况填充第二个 rrd 文件,这样我就可以添加到 sh 文件代码来生成该数据的图表。
如何使用 CPU 和 MEM 使用数据填充 RRD 文件? 请不要使用第三方工具!
I have a Lighttpd server (on Centos) and would like to display 4 graphs: lighttpd traffic, lighttpd requests per second, CPU usage and MEM usage. I've set place for rrd database for lighttpd config like this:
rrdtool.binary = "/usr/bin/rrdtool"
rrdtool.db-name = "/var/www/lighttpd.rrd"
And put into my WWW cgi-bin sh file that gets data from lighttpd RRD file and creates graphs of traffic and requests per second like this:
#!/bin/sh
RRDTOOL=/usr/bin/rrdtool
OUTDIR=//var/www/graphs
INFILE=/var/www/lighttpd.rrd
OUTPRE=lighttpd-traffic

Basically it's not my script, i get it from somewhere from the internet.
Now i would like to do the same for CPU usage and MEM usage.
I don't like to use any additional packages!
As you can see lighttpd populates lighttpd.rrd file with traffic data and requests per second. Now i would like to the system to populate second rrd file with CPU and MEM usage, so i can add to sh file code to generate graphs for this data.
How can I populate RRD file with CPU and MEM usage data?
Please, NO THIRD-PARTY tools !

技巧是从 proc 文件系统中的文件读取数据并使用 sed/awk 提取实际值。创建一个 DS 类型 GAUGE 的 rrd 文件来存储数据...请查看 www.rrdtool.org 上的教程来开始操作。
