Ezine 203 - Abandon Ping in Favor of Test-Connection
Test-Connection Measures Response Time for Website
Let us experiment with PowerShell's Test-Connection and see how it's more interesting and flexible than good old ping.
One of the most attractive reasons for giving PowerShell a try is that you can still use familiar cmd.exe command such as ipconfig /all and ping in PowerShell. Once started you, can build on existing knowledge and soon achieve higher levels of skill than were possible with cmd.exe.
Taking ping as example, you can use the same switches that you used in DOS, but better still, switch to PowerShell's equivalent called test-Connection. The benefits of test-Connection are two-fold, you can measure average response times, something that's not possible with ping, and you can employ test-Connection as a vehicle for learning about PowerShell's mathematical cmdlets such as measure-Object and [System:Math].
This Week's Mission - Test-Connection Measures Response Time for Website
Getting Started: Switch from Ping to test-Connection
# PowerShell's Equivalent of Ping
# Now launch PowerShell and try:
Benefits of Test-Connection Compared to Ping
This following script contains 3 elements:
There is no doubt that you could make a much more efficient script, however my version pays homage to divide and rule. I believe that the easiest way to learn scripting is to break the task into chunks, then bolt all the bits together. Furthermore, my version encourages you to make alterations, for example, change the value of $Server and the number of tests to 'count'.
# PowerShell script to measure a server's response time
Note 1: Test-Connection is more flexible than Ping. You can research more properties for your scripts by prefixing get-Help to test-Connection, also try suffixing get-Member.
Note 2: ResponseTime is a property of test-Connection, the benefit of using this PowerShell cmdlet rather than ping is that we can calculate average connection times.
Note 3: At first sight [System.Math]:: seems a strange way to call for mathematical functions such as Round, Truncate or log, however you soon get used to its ways! See more on Test-Connection
Experiment: You cannot learn without making mistakes, try changing the parameters below, some will make no sense, while others will be predictable. Only by experimenting will you truly understand how to handle PowerShell's math functions.
ResponseTime -Sum (Also -Maximum, -Count)

Summary of Test-Connection
One reason for learning PowerShell that you can still use familiar command such as ipconfig /all and ping in the PowerShell GUI. The benefits of test-Connection are two-fold, you can measure average response times, something that you could not do with ping, and you can use test-Connection as a vehicle for learning about PowerShell's mathematical cmdlets such as measure-Object and [System:Math].
