Issue/Introduction:
Why Doesn't My xenserver Probe Show CPU Utilization?
Environment:
Release:
Component: CAUIM
Resolution:
The xenserver device does not export CPU utilization content by default. This must be enabled on the xenserver with the following commands:
> xe host-list
uuid ( RO) : <uuid_redacted>
name-label ( RW): xen1
name-description ( RW): Default install of XenServer
> xe host-param-set uuid=<uuid_redacted> other-config:rrd_update_interval=1
==> The xenserver itself must be restarted to put this parameter into effect.
The following command can be issued to verify the setting:
> xe host-param-get uuid<uuid_redacted> param-name=other-config
This is an example of host-param-get showing that the required setting is NOT in force:
[[email protected] ~]# xe host-param-get uuid=<uuid_redacted> param-name=other-config
agent_start_time: 1324281474.; boot_time: 1324281314.; iscsi_iqn: iqn.2010-07.com.example:2b72aff9
This example shows output that verifies rrd_update_interval: 1
[[email protected] ~]# xe host-param-get uuid=<uuid_redacted> param-name=other-config
agent_start_time: 1327345802.; boot_time: 1327345723.; rrd_update_interval: 1; iscsi_iqn: iqn.2011-10.com.example:6c7fe7c3
