Understanding the VASA Provider dashboard


Understanding the VASA Provider dashboard
The VASA Provider dashboard provides an overview of the virtual datastores and virtual machines that are configured in your vCenter Server. The dashboard enables you to monitor the performance of all your top virtual datastores and virtual machines on a single page.
You must register OnCommand API Services with VASA Provider if you want to view the VASA Provider dashboard. OnCommand API Services provides details about space savings and IOPS metrics, and the vCenter Server provides information about datastore capacity.
You must have a dedicated instance of OnCommand API Services for VASA Provider.
One instance of OnCommand API Services cannot be shared with multiple VASA Provider instances.
You must follow the installation instructions from the OnCommand API Services Installation and Setup guide after downloading and installing OnCommand API Services from the NetApp Support Site.
You must not perform any configuration for OnCommand API Services post installation, as the virtual appliance for Virtual Storage Console (VSC), VASA Provider, and Storage Replication Adapter (SRA) takes care of configuration.

The storage system must be running ONTAP 9.3 for OnCommand API Services to gather details of IOPS, latency, and throughput.
The virtual appliance for VSC, VASA Provider, and SRA completes the required configuration for OnCommand API Services. The VASA Provider dashboard includes an Overview section and portlets.
Overview
The Overview section of the VASA Provider dashboard provides information about the capacity, space savings, and IOPS of the virtual volume (VVol) datastores that are managed by VASA Provider for ONTAP. The Overview section displays the following information:
The VVol datastore capacity is displayed in the form of a pie chart. The pie chart aggregates the used capacity and free space of all of the VVol datastores and provides a summarized view to the dashboard.
The total space savings across all of the data VVols that is obtained by aggregating deduplication savings and compression savings at the volume level is displayed in the form of a ratio as well as a bar graph for ease of readability.
The IOPS values for read IOPS, write IOPS and total IOPS are displayed. All of the IOPS values are calculated by adding the IOPS value of each data VVol. The IOPS value that is displayed on the dashboard are obtained from ONTAP.
The VASA Provider dashboard provides an overview of the data VVols in your vCenter Server at a given time. If you have enabled linked mode for your vCenter Servers, then you must select the required vCenter Server by using the vCenter Server drop-down menu. All of the information that is available in the VASA Provider dashboard is provided by OnCommand API Services managing ONTAP 9.3 or later.
Portlets
The VASA Provider dashboard includes portlets for VVol datastores and virtual machines.
VVol Datastores
The VVol Datastores portlet displays the total number of virtual datastores and the top five virtual datastores in your vCenter Server based on your selected category. You can categorize the top five virtual datastores in the VVol Datastores portlet according to one of the following data VVol parameters:
The virtual datastores with the highest or lowest free space are displayed based on your selection. The percentage of used space is displayed.
The top five virtual datastores with the highest or lowest IOPS are displayed based on your selection. The IOPS information for virtual datastores is retrieved from OnCommand API Services.
The top five virtual datastores with the highest or lowest latency are listed based on your selection. The maximum latency across all of the data VVols in a particular datastore that are managed by VASA Provider is displayed.
You can position your cursor over the progress bar for the space utilized parameter to view the actual values for a virtual datastore. Each virtual datastore name is a link that navigates to the Performance tab or the last visited tab for that virtual datastore in your vCenter Server.
Virtual Machines
The Virtual Machines portlet displays the total number of virtual machines and the top five virtual machines that are using the virtual datastores that are provisioned by VASA Provider. You can categorize the Virtual Machines portlet according to one of the following parameters:
The highest committed capacity for a particular virtual machine across all of the VVol datastores is displayed.
The highest latency value across all of the data VVols that are associated with a virtual machine is displayed.
The sum of all IOPS values across all data VVols associated with a virtual machine is displayed.
The highest throughput across all of the data VVols that are associated with a virtual machine is displayed.
The sum of the logical space across all of the data VVols that are associated with a virtual machine is displayed.
The time since when the virtual machines are available on an ESXi host is displayed.
Note: The IOPS data from ONTAP is rounded off and displayed on the dashboard. You might notice a mismatch between the displayed IOPS value and the actual IOPS value in the Overview section and the portlets of the VASA Provider dashboard.
