Monitoring the Datacenter And Host System
Datacenter and host system monitoring lets an administrator monitor infrastructure health by displaying hardware (server and storage) and virtualization-related events on the Tasks & Events tab in vCenter. Additionally, critical hardware alarms can trigger the Dell Management Plug-in to put the host system into a maintenance mode, and in certain cases migrate the virtual machines to another host system. For hosts prior to 12G, the Dell Management Plug-in forwards OMSA alarms, and creates new ones for specific events. You can use these alarms to trigger actions that vCenter allows, like a reboot, maintenance mode, or migrate. For example, when a dual power supply fails and an alarm is created, the resulting action can be to migrate the virtual machine on that machine to a new one.
To perform monitoring:
- Configure the Event and Alarm settings.
- Configure OMSA trap destinations, if needed (hosts prior to 12G).
- Use the Tasks & Events tab in vCenter to review event information.
