When applying you initially apply a template to one or more hosts, the idea is to have all the applicable hosts adopt the service configuration configurations defined in that the template. However, if you want to control whether you can add, modify, or delete services on certain hosts, BloxOne offers lock type options. These options allow you to define how hosts adopt service configurations while being associated with a template.
For a host associated with a template, BloxOne also calculate indicates whether the services on the host have changed in relation to the template; this change is called drift. BloxOne also calculates the drift state of a host when service changes are allowed on the host. The drift state implies whether the host to which a specified template is applied adheres to the defined specifications or not. The drift state can be True or False, as follows:
...
Lock Type | Drift State | Description |
|---|---|---|
Locked | False | When a host is Locked, it is associated with the applied template. Therefore, no service addition, modification, or deletion is allowed on the host. The drift state is False when a host is in the Locked state since there is no drifting from the template. If you want certain hosts to adhere to all the updates made to the applied template, you can lock them to the template. In other words, whenever changes are made to the template, the services on these locked hosts will be immediately reconciled based on changes made to the template. When you modify the template, the modification will apply to locked hosts automatically, without you having to approve it. However, the modification will not apply to hosts whose Lock Type is Unlocked or Monitored. |
Unlocked | N/A | When a host is in the Unlocked state, it is not locked to the applied template. Therefore, service addition, modification, and deletion on the host are allowed. The drift state is not calculated or displayed for an unlocked host, meaning BloxOne does not perform any checks on the drift state is unchecked. You can assign this lock type to a host if you want to be able to modify its services but do not need to monitor its drift state in relation to the applied template. |
Monitored | true or false | When you first apply a template to a host, the lock type of the host is set to Monitored, and the drift state is set to False. In this state, you can add new services to the host. When you do that, the drift state will change to True, indicating that services on the host have drifted from the applied template. You can assign this lock type to a host and monitor its drift state in relation to the applied template for testing purposes. |
