VMware vCenter Operations Manager presents three overall views of your virtual infrastructure: Health, Risk and Efficiency, represented by badges on a consolidated dashboard.
- Health describes the current state of the virtual infrastructure. Its score is based on workloads, anomalies, and faults of host and virtual machine infrastructure.
- Risk presents short-term capacity and is based on time remaining, capacity remaining and stress calculations of the environment.
- Efficiency presents a long-term capacity view of the environment and is calculated from reclaimable waste and density data.
Higher scores are preferable for Health and Efficiency, while a lower score is preferred for Risk.
The Operations, Planning, Alerts, Analysis, and Reports tabs provide additional views of the environment. The left-hand pane on the Operations and Planning tabs shows the current virtual infrastructure, as in vCenter. Drill down capability in the dashboard and other areas of Operations Manager allows admins to quickly identify issues to be rectified.
Operations manager is a vApp containing two virtual machines that are treated as an entity.
- The Analytics VM gathers data from vCenter and other sources into a File System Database (FSDB). The analytics engines process the data using Postgres/FSDB databases to store the results.
- The User Interface VM provides webapps for viewing the data and administering the environment.
The vApp requires different resources based on the environment to be monitored and analyzed. The following resources are applied to the vApp, not the individual machines.
- Supports up to 1,500 powered on virtual machines.
- 4 vCPUs
- 16 GB memory
- Supports 1,500 to 3,000 powered on virtual machines.
- 8 vCPUs
- 24 GB memory
- Supports 3,000 to 6,000 powered on virtual machines.
- 16 vCPUs
- 32 GB memory
Depending on the number of VMs above and the data retention, the disk requirements of the VMs ranges from 120 GB (default) to 400 GB for the UI VM; and from 200 GB (default) to 2.4 TB for the Analytics VM.
vCenter Operations Manager also integrates with Site Recovery Manager to provide increased protection for disaster recovery. It is currently available in four versions: Standard for small vSphere environments; Advanced for large vSphere environments; Enterprise for virtual and cloud infrastructure; and Enterprise Plus for cloud and heterogeneous environments.
