Measures reported by XenToolStatusTest

XenServer Tools, the XenServer paravirtualization tools, provide high speed I/O for enhanced disk and network performance. XenServer Tools must be installed on each virtual machine (Windows and Linux) in order to use the xe CLI or XenCenter; moreover, VM performance will significantly deteriorate unless the tools are installed. Without the tools installed, you will not be able to do any of the following:

  • Cleanly shut down, reboot or suspend a VM.
  • View VM performance data in XenCenter.
  • Migrate a running VM (via XenMotion).
  • Create quiesced snapshots or snapshots with memory (checkpoints), or revert to snapshots.
  • Adjust the number of vCPUs on a running Linux VM (Windows VMs require a reboot for this to take effect).
Using this test, you can ascertain whether the XenServer tools are installed or not on a VM.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Tool_status Indicates whether/not XenServers Tools has been installed on this VM.   If XenServer Tools is installed on a VM, this measure will report the value Yes. On the other hand, if XenServer Tools is not installed on a VM, this measure will report the value No.

The numeric values that correspond to each of the measure values discussed above have been detailed in the table below:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports Yes or No to indicate whether XenServer Tools is installed on a VM or not. The graph of this measure however, represents the same using the numeric equivalents only - i.e., 0 or 1.

Tool_uptodate Indicates whether the latest version of XenServer Tools has been installed on this VM. Number If the latest version of XenServer Tools is installed on a VM, this measure will report the value Yes. On the other hand, if an older/obsolete version of XenServer Tools is installed on a VM, this measure will report the value No.

The numeric values that correspond to each of the measure values discussed above have been detailed in the table below:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports Yes or No to indicate the version of XenServer Tools installed on a VM. The graph of this measure however, represents the same using the numeric equivalents only - i.e., 0 or 1.
