This PowerShell application will illustrate how to pull out the rolled up Http Statistics taking from all of the Http Profiles.
I was digging through the iControl interfaces the other day and it's still amazing to me, after being around since the beginning of the API, to find new and cool stuff hiding in there. Today's find was lurking within the System.Statistics interface. There are literally dozens of method calls to pull out all sorts of useful statistics and the one I picked for today is the System HTTP Statistics which are a rollup of all HTTP Profiles' statistics. This application will build a report on everything you wanted to know from an HTTP level such as how many 5xx responses have been served to the number of bytes of compressed video and the RAM cache hits and misses.

## Invoke-Inline.ps1 (originally from Lee Holmes)
## Library support for inline C#
##
## Modified by Joel Bennett to accept include statements, and return collections
##
## Usage
## 1) Define just the body of a C# method, and store it in a string. "Here
## strings" work great for this. The code can be simple:
##
## $codeToRun = "Console.WriteLine(Math.Sqrt(337));"
##
## or more complex, using result.Add():
##
## $codeToRun = @"
## string firstArg = (string) ((System.Collections.ArrayList) arg)[0];
## int secondArg = (int) ((System.Collections.ArrayList) arg)[1];
##
## Console.WriteLine("Hello {0} {1}", firstArg, secondArg );
##
## result.Add(secondArg * 3);
## "@
##
## 2) If you must pass arguments, you should make them strongly-typed,
## so that PowerShell doesn't wrap it as a PsObject.
##
## 3) Invoke the inline code, optionally retrieving the return value. You can
## set the return values in your inline code by assigning it to the
## "return" collection as shown above.
##
## $result = Invoke-Inline $usingStatements, $codeToRun $arguments
## $result = Invoke-Inline $codeToRun $arguments
##
##
## If your code is simple enough, you can even do this entirely inline:
##
## Invoke-Inline "Console.WriteLine(Math.Pow(337,2));"
##
