Viewing alarms and events setting
Once you configure alarms and events, you can view if the vCenter alarms for hosts are enabled and which event posting level is selected
on the settings tab.
1. In OpenManage Integration for VMware vCenter, in the Manage > Settings tab, under vCenter Settings, expand Events and
Alarms.
The following details are displayed:
• vCenter alarms for Dell hosts — Displays either Enabled or Disabled.
• Event posting level
2. Configure events and alarms. See Configuring events and alarms.
To view the event posting levels, see About events and alarms.
Viewing events
Ensure that you configure events before you can view them in the Events tab. See Configuring events and alarms.
View the events for a host, cluster, or data center in the events tab.
1. In the OpenManage Integration for VMware vCenter Navigator, click Hosts, Datacenter or Clusters.
2. In the Objects tab, select a specific host, data center, or cluster for which you want to view events.
3. In the Monitor tab, click Events.
4. To view the event details, select a specific event.
Hardware component health—Proactive HA
Proactive HA is a vCenter (vCenter 6.5 and later) feature that works with OMIVV. When you enable Proactive HA, the feature safeguards
your workloads by proactively taking measures during redundant component failures in a host.
NOTE:
All hosts from the Dell PowerEdge 12th generation and later, and the ESXi versions v6.0 and later that are part of
a connection profile and successfully inventoried are eligible for Proactive HA.
To assess the status of redundant host server components, the OMIVV appliance updates the host component health status change to
the vCenter server. The available status states of the major host server components, such as power supply, fans, and internal dual SD
module (IDSDM) are:
• Healthy (green check mark)—component operating normally.
• Warning (yellow triangle with exclamation point)—component has a noncritical error.
• Critical (red X)—component has a critical failure.
When OMIVV detects a component health status change (either through traps or polling), the health update notification of the
component is forwarded with the status to the vCenter server. Based on the notification, the vCenter server takes either a manual or an
automatic action, as configured by you. The vCenter server takes either of the following actions:
• Place host in quarantine mode
• Place host in maintenance mode
Configuring Proactive HA for Rack servers
To configure for Rack servers, perform the following steps:
1. Create a connection profile and associate hosts with connection profile. See Creating a connection profile.
2. Verify that hosts inventory is completed successfully. See Viewing hosts inventory.
3. Verify that the SNMP trap destination in iDRAC is set as the OMIVV appliance IP address.
