Get-HpcNodeStateHistory
Retrieves the history of changes to the state of the nodes in the HPC cluster for the specified time period.
Syntax
Get-HpcNodeStateHistory [-StartDate] <DateTime> [-EndDate] <DateTime> [<CommonParameters>]
Detailed Description
Retrieves the history of changes to the state of the nodes in the HPC cluster for the specified time period. The time period is the period after the specified start date and before the specified end date.
You can schedule this cmdlet to run daily and export the history of node states to a database. You can then use this database to track node availability.
Parameters
-EndDate <DateTime>
Specifies a DateTime object for the end date and time for the time period for which you want to retrieve the history of changes to the node states. Use the Get-Date cmdlet to get a DateTime object for a date and time.

Return Type |
An array of HpcNodeHistory objects. |
Notes
The time stamps in the history of node states are in the time zone of the local computer instead of the time zone of the head node for the cluster. Run this cmdlet on a computer located in the same time zone as head node to get consistent results.
Example 1
C:\PS>Get-HpcNodeStateHistory -StartDate (Get-Date).AddDays(-1) -EndDate (Get-Date)
Retrieves the history of changes to the node states for the past day. Run this cmdlet daily at midnight or some other appropriate time to update the database you use to track node availability.
