Managing Leases for Multi-Machine Services

Leases are controlled at the multi-machine service level. Lease operations such as change, extend, and

expire are not available for individual component machines.

The lease period for a multi-machine service always overrides the lease on its component machines.

A component machine always has the same lease period as the multi-machine service.

When the expiration date for a multi-machine service changes, that change is applied to all its

component machines.

Component machines cannot expire earlier than the multi-machine service to which they belong.

When a multi-machine service expires, all its component machines expire at the same time. The

multi-machine service and its component machines are destroyed immediately when the lease

expires.

Reclamation Overview

Tenant administrators can use metrics such as low CPU use, low memory use, or low hard disk use to

reclaim virtual machines in their tenant and help control resources.

You can use the basic metrics provided by vRealize Automation to sort and filter metrics information for all

of your machines, or you can configure a vRealize Operations Manager endpoint to provide metrics and

health badges for your vSphere virtual machines.

You can use the metrics to identify underused machines that might be candidates for reclamation. Select

the candidate machines and send a reclamation request to the owners of the machines. The machine

owner has a fixed period of time to respond to the request. If the machine is still in use, the owner can

stop the reclamation process and continue using the machine. If the machine is no longer needed, the

owner can release the machine for reclamation, in which case the machine lease is ended. If the owner

does not respond in a timely manner, a lease determined by the administrator is imposed. If the owner

continues to take no action, the machine is powered off on the new expiration date, the machine is

reclaimed, and the resources are freed.

Conﬁgure a Metrics Provider

You can configure vRealize Automation to use vRealize Operations Manager health and resource metrics

for vSphere virtual machines.

For more information about vRealize Operations Manager health badges and metrics, see the

vRealize Operations Manager documentation.

Prerequisites

Create a vRealize Operations Manager user account with view and resource metrics query privileges

for all vSphere servers that you integrate with vRealize Automation.
