[XenServer 6.5] Monittoring average CPU frequency

 I was successful to monitor average CPU frequency on XenServer 6.5 by Zabbix 2.2 by followings, although "cpu MHz" in /proc/cpuinfo cannot monitor real-time CPU frequency unlike other Linux distributions..

○ Environment:

CPU : AMD FX-9590 (4.7 GHz)
Mother board : ASRock 990Fx Extream 9
Phisycal Memory : 8G x 2
HDD : Western Digital　WD2002FAEX x 2  (RAID 1 by mdadm)
Hypervisor : Citrix  XenServer 6.5

○xenpm command

1.xenpm start command starts measuring CPU frequency and status,  when the CTLR-C is pressed the result of the term from command execution to CTLR-C  will be shown on the console.

[root@servername ~]# xenpm start
Start sampling, waiting for CTRL-C or SIGINT or SIGALARM signal ...
(#Press CTRL-C.)

 If the argument for timeout(sec.) is given to xenpm command like the below, the user don't need to press CTRL-C to show the results.

[root@servername ~]# xenpm start 10

○ Setting Zabbix 2.2 Agent on XenServer 6.5

1. Set the sudo configuration on XenServer .5 so that zabbix user can execute xenpm command.Add the following to /etc/sudoers if zabbix user is added to wheel group on XenServer 6.5.

 %wheel  ALL=(ALL)       NOPASSWD:       /usr/sbin/xenpm

2.  Set Timeout parameter in /etc/zabbix/zabbix_server.conf on Zabbix Server. Add the following to conf file.(Default = 3).

Timeout=30

3. Set Timeout parameter in /etc/zabbix/zabbix_agentd.conf on XenServer 6.5. Add the following to conf file.(Default = 3)

Timeout=30

4. Add the followings to /etc/zabbix/zabbix-agentd.conf on XenServer 6.5 to report .

 UserParameter=xenpm_start[*],sudo xenpm start 10|grep $2|sed -n -e $1"p"|awk '{print $$3}'

5. Restart Zabbix server and agent on XenServer 6.5 in order to reflect configuration changes.

  [root@servername ~]# /etc/init.d/zabbix-agent restart

  [root@servername2 ~]# /etc/init.d/zabbix-server restart

6. Add a new Item for average CPU frequency.of XenServer 6.5 on Zabbix Server

7. You can get the following result after creating the graph.
