Provides detailed CPU usage information about a SQL Server's process
"If there are a lot of processes running on your instance and the CPU is very high, then it's hard to find the exact process eating up your CPU using just the SQL Server tools. One way to correlate the data between what is running within SQL Server and at the Windows level is to use SPID and KPID values to get the exact process."
This command automates that process.
Note: This command returns results from all SQL instances on the destination server but the process column is specific to -SqlInstance passed.
Get-DbaCpuUsage [-SqlInstance] <DbaInstanceParameter> [[-SqlCredential] <PSCredential>] [[-Credential] <PSCredential>] [[-Threshold] <Int32>] [-EnableException] [<CommonParameters>]
PS C:\> Get-DbaCpuUsage -SqlInstance sql2017
Logs into the SQL Server instance "sql2017" and also the Computer itself (via WMI) to gather information
PS C:\> $usage = Get-DbaCpuUsage -SqlInstance sql2017 PS C:\> $usage.Process
Explores the processes (from Get-DbaProcess) associated with the usage results
PS C:\> Get-DbaCpuUsage -SqlInstance sql2017 -SqlCredential sqladmin -Credential ad\sqldba
Logs into the SQL instance using the SQL Login 'sqladmin' and then Windows instance as 'ad\sqldba'
The target SQL Server instance or instances.
Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
