The Operations Overview dashboard provides you with a high-level view of objects which make up your virtual environment. You can view an aggregate of the virtual machine growth trends across the different data centers that vRealize Operations Cloud monitors.

You can also view a list of all your data centers with inventory information about how many clusters, hosts, and virtual machines you are running in each of your data centers. By selecting a particular data center, you can narrow down on the areas of availability and performance. The dashboard provides a trend of known issues in each of your data centers based on the alerts which have triggered in the past.

You can also view a list of the top 15 virtual machines in the selected data center which might be contending for resources.

You can use the dashboard widgets in several ways.
  • Environment Summary: Use this widget to view a summary of the overall inventory of your environment.
  • Select a Datacenter: Use this widget to select the data center for which you want to view operational information. You can use the filter to narrow your list based on several parameters. After you identify the data center you want to view, select it. The dashboard is automatically populated with the relevant data.
  • Cumulative Up-time of all Clusters: Use this widget to view the overall health of the clusters in the data center you selected. The metric value is calculated based on the uptime of each ESXi host, when you take into account one host as the HA host. If the number displayed is less than 100%, it means that at least two hosts within the cluster were not operational for that period.
  • Alert Volume (in selected DC): Use this widget to view the breakdown of alert trends based on their criticality.
  • Top-N: You can also view a list of 15 VMs that had the highest average CPU contention, the highest use of memory, and the highest disk latency for the last 24 hours. To obtain specific data, you can manually set the time to the time of the problem. To set the time, click the Edit Widget icon from the title bar of the widget and edit the Period Length drop-down menu.
