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

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 restart6. Add a new Item for average CPU frequency.of XenServer 6.5 on Zabbix Server
