Update Manager checks for host patches, and extensions at regular intervals. Generally, the default schedule settings are sufficient, but you can change the schedule if your environment requires more or less frequent checks.

In some cases you might want to decrease the duration between checks for updates. If you are not concerned about the latest updates and want to reduce network traffic, or if you cannot access the update servers, you can increase the duration between checks for updates.

By default the task to download update metadata and binaries is enabled and is called VMware vSphere  Update Manager Update Download task. By modifying this task, you can configure checking for updates.You can modify the VMware vSphere  Update Manager Check Notification task in one of the following ways:
  • The Configure tab of the Update Manager Administration view.
  • In the vSphere Web Client, navigate to Monitor tab, select the Tasks & Events tab, and select Scheduled Tasks.
