Datastore Performance Summary
Use Search to find a template, report or dashboard by name. Search is case insensitive, supports partial entries, and will display a list of potential matches.
As you enter the name in the Search field, up to 10 potential matches are displayed. If the template, report or dashboard is shown, you can select and run it directly from the match list. You can also click All Items in the match list to go directly to the Search Results.
StorageConsole provides different navigation options to slice and examine your collected data. You can explore the data by using the APTARE customizable report templates or by using parts of your IT infrastructure as entry points. The Inventory Navigator serves as a browser for your infrastructure by object type.
Use the Reports tab to examine the StorageConsole catalog of templates, dashboards and reports - organized by products along with user-created, and system folders. This report is located here:
List Datastores with disk I/O statistics, including read/write latency.
Disk Read and Write Latency is available only for ESX Hosts (not VMs). Therefore, latency performance charts are available only for partitions of Type=Host.
Note: If some Datastores are missing from this report, it is likely due to virtual systems that have a status of pending deletion and therefore do not have any performance data to display.

Disk I/O Data Xfer (KB/sec)
Disk I/O average (read xfer and write xfer) for all disks; the total for this column is the sum of the read and write averages
Disk I/O Latency (ms)
Disk I/O wait time, which is the average for the report’s Group By interval; Disk Read and Write Latency is available only for ESX Hosts (not VMs). Therefore, latency performance charts are available only for partitions of Type=Host
Disk Read Data Xfer (KB/sec)
Average disk read transfer rate for the report’s Group By interval
Disk Read # Reads
Sum of the total number of disk reads for the report’s Group By interval
Disk Read Latency (ms)
Disk read wait time, which is the average for the report’s Group By interval; Disk Read and Write Latency is available only for ESX Hosts (not VMs). Therefore, latency performance charts are available only for partitions of Type=Host
Disk Write Data Xfer (KB/sec)
Average disk write transfer rate for the report’s Group By interval
Disk Write # Writes
Sum of the total number of disk writes for the report’s Group By interval
Disk Write Latency (ms)
Disk write wait time, which is the average for the report’s Group By interval; Disk Read and Write Latency is available only for ESX Hosts (not VMs). Therefore, latency performance charts are available only for partitions of Type=Host.
