Show What You Learned About PowerShell
Homework Assignment #1: Creating a formatted report of a selected scoped of peak paged memory.
- By Jeffery Hicks
If you've been in class from the beginning you
should have learned quite a bit about PowerShell
by now. So I think it is time for a homework assignment.
Before the next column, see if you can figure
out how to do this in PowerShell:
Create a formatted report of the top 10 processes
where the peak paged memory is greater than
10MB. For each process select its process id,
name, paged memory, peak paged memory, working
set and peak working set sizes.
You should be able to write a single PowerShell
command to accomplish this task. I hope you realize
that you'll need to send objects from one cmdlet
to another through the pipeline.
Let me give you a few more hints. First, you'll
need to know the right property names for a process
object. Do you remember what cmdlet will show
you an object's members, such as methods and properties?
That's right -- Get-Member. Pipe Get-Process to
Get-Member to find the right property names.
I'm asking you to filter the process objects
where the peak paged memory size is greater than
10MB and then select the top 10 based on peak
paged memory size. The filtering is probably unnecessary
in a production-oriented script, but I wanted
to fill out the exercise.
Here's another hint: You'll need to select items
in descending order after they are sorted. To
display a nicely formatted report, you'll likely
need to use the Format-Table cmdlet. If you read
this paragraph closely you should detect some
hints as to what cmdlets to use.
I encourage you to review the help file for all
the cmdlets you are likely to need to complete
the assignment. You should write the most complete
and efficient PowerShell expression you can. There
may be several ways to finish this assignment.
I'll be back next week with a possible solution.
