Setting Default Cloud VM Set Properties

You can set defaults for some of the Cloud VM Set properties so that, when you create a new Cloud VM Set, those defaults are automatically populated. Changes to these properties are only applied to Cloud VM Sets created after the changes are saved. The changes do not affect any existing Cloud VM Sets.

Log into the KeyControl webGUI on any node in the cluster using an account with Cloud Admin privileges.
In the top menu bar, click Settings.

In the Cloud Settings section, click Cloud Settings and specify the options you want to use.

Options

Option	Description
Heartbeat	The length of time between the heartbeats each VM in the set sends to KeyControl to verify that the connection between them is functioning normally. You can specify seconds, minutes, hours, or days. The default is 5 minutes. This value should be set to a minimum of 10 seconds. If changes have been made to the VMs through the KeyControl webGUI, those changes are communicated to the VMs during the heartbeat. That means if the heartbeat is set to 5 minutes, then it can take up to 5 minutes for any changes made in the KeyControl webGUI to be applied to the VMs in the set. If a VM cannot reach KeyControl during the heartbeat, the VM continues to run but any changes made in KeyControl are not picked up by the VM until the next successful heartbeat. KeyControl sets the status of the VM to Unreachable, but it takes no further action unless the heartbeat continues to fail after the Grace Period has expired.
Grace Period	The length of time that can pass without a successful heartbeat. The default is 1 day. You can specify the grace period in seconds, minutes, hours, or days. If a VM remains unresponsive past the grace period, access to the data on the VM will be unavailable until the VM is re-authenticated with KeyControl.
