Conditions


Conditions are tests that are performed on the attributes of virtual machines/instances and hosts. They are categorized as either a host condition or a VM condition, and listed under the Conditions accordion in Control Explorer.

A condition consists of two important elements:

  • Scope is an optional VM/instance or host attribute check

  • Expression is a mandatory check

For example, we scope a condition that will apply to virtual machines (or instances) running Windows Operating Systems only, and then run an expression to check whether a specific version of an antivirus is installed.

Note

Note

If a policy does not have any condition, scope, or expression, then it is unconditional and always returns a true value.
