OpenManage Integration for VMware vCenter Version 4.0 Web Client User's Guide

About events and alarms for hosts

You can edit events and alarms from the OpenManage Integration for VMware vCenter within the Manage > Settings tab. From here, you can select the event posting level, enable alarms for Dell hosts, or restore default alarms. You can configure events and alarms for each vCenter or all at once for all registered vCenters.

The following are the four event posting levels:

Table 1. Event posting levelThis table provides information about event posting level.
Event	Description
Do not post any events	Do not allow the OpenManage Integration for VMware vCenter forward any events or alerts into related vCenters.
Post all events	Post all events, including informal events, that the OpenManage Integration for VMware vCenter receives from managed Dell hosts into related vCenters.
Post only critical and warning events	Posts only events with either a Critical or Warning criticality into related vCenters.
Post only virtualization-related critical and warning events	Post virtualization-related events received from hosts into related vCenters. The virtualization-related events are events that Dell selects to be most critical to hosts that run virtual machines.

When you configure the events and alarms, you can enable them. When enabled, the critical hardware alarms can trigger the OMIVV appliance to put the host system into a maintenance mode, and in certain cases, migrate the virtual machines to another host system. The OpenManage Integration for VMware vCenter forwards events received from managed Dell hosts, and creates alarms for those events. Use these alarms to trigger actions from vCenter, like a reboot, maintenance mode, or migrate.

For example, when a dual power supply fails and an alarm is created, the resulting action puts the machine into maintenance mode, which results in workloads being migrated to a different host in the cluster.

All hosts outside of clusters, or in clusters without VMware Distributed Resource Scheduling (DRS) enabled, can see virtual machines being shut down due to a critical event. DRS continuously monitors usage across a resource pool and intelligently allocates available resources among virtual machines according to business needs. To ensure that virtual machines are automatically migrated on critical hardware events, use clusters with DRS configured Dell alarms. The details of the on-screen message list the clusters on this vCenter instance that might be impacted. Ensure that you confirm that the clusters are impacted before enabling events and alarms.

If you ever need to restore the default alarm settings, you can do so with the Reset Default Alarm button. This button is a convenient option to restore the default alarm configuration without uninstalling and reinstalling the product. If any Dell alarm configurations have been changed since installation, those changes are reverted by using this button.

NOTE: To receive Dell events, ensure that you enable the events.

NOTE: The OpenManage Integration for VMware vCenter preselects the virtualization-related events that are essential to hosts successfully running the virtual machines. By default, the Dell host alarms are disabled. If Dell alarms are enabled, the clusters should use DRS to ensure that the virtual machines that send critical events are automatically migrated.
