[Xen-users] Monitoring and logging CPU utlization for all domains

["John Lim" <jlim@xxxxxxxxxxx>]

Hi,

 

Here’s a script that I thought might be useful for everyone using Xen.

 

In order to monitor and log CPU utlisation of all domains, I have implemented the following Perl script:

 

  http://phplens.com/xenstat.pl.txt

 

 

 

Example usage:

===========

 

[Domain-0~]# perl xenstat.pl

cpus=2

     54_garuda_0  0.49% cpu usage  3034.56 sec over 3.61 days

    59_gyrfalcon  3.65% cpu usage  5032.13 sec over 0.80 days

        Domain-0  1.56% cpu usage  9746.05 sec over 3.61 days

2009-09-29 10:38:12 39  1 37 23

2009-09-29 10:38:17 80  0  7 13

2009-09-29 10:38:22 54  0  4 42

2009-09-29 10:38:28 25  1  3 71

 

Where statistics is:

DATE       TIME       GARUDA   GYRFALCON DOM0  IDLE

                       CPU%     CPU%      CPU%  CPU%

2009-09-29  10:38:12    39       1         37    23

 

 

 

REST-ful Logging

=============

The other nice feature is that xenstat.pl can generate a URL and if you have wget installed

It will send the URL to a web server:

 

 

[root@server ~]# perl xenstat.pl 10 1  http://192.168.0.1/

 

Which will call the following url once after 10 seconds of monitoring the CPU:

 

http://192.168.0.1/?54_garuda_0=0&59_gyrfalcon=2&Domain%2D0=2&
