As we already discussed, our goal here is to work with processes.

1. List out the cmdlets that help you work with processes.

PS> Get-Command -Noun Process

We get five cmdlets. What we initially need is Get-Process.

2. Run the cmdlet to see what it shows.

PS> Get-Process

The output is a long table of processes, the memory they are consuming, the CPU time they are using, etc.

3. Get the total count of processes currently running in the system.

PS> (Get-Process).Count

4. Now, fetch the average of the pages of memory used by the processes. The term for this is Working Set, denoted as WS.

PS> Get-Process | Measure-Object -Property WS -Average

5. There are other fields in the hash table as well. Let us get all of that information.

PS> Get-Process | Measure-Object -Property WS -Average -Sum -Minimum -Maximum

6. Get the average, sum, minimum and maximum for both, the working set, as well as the CPU.

PS> Get-Process | Measure-Object -Property WS, CPU -Average -Sum -Minimum -Maximum
