Monitoring Application Performance on the .NET Compact Framework Part IX - Version 2 performance counters (Part VII: Windows.Forms counters)
This is the seventh (and final) in the series describing the .NET Compact Framework v2 performance counters. For a complete listing of the previous installments, please see the list below.
Pre-requisite:
Monitoring Application Performance on the .NET Compact Framework Part I - Enabling performance counters
.NET Compact Framework Version 1:
Monitoring Application Performance on the .NET Compact Framework Part II - Version 1 performance counters
.NET Compact Framework Version 2:
Monitoring Application Performance on the .NET Compact Framework Part III - Version 2 performance counters (Part I: Loader counters)
Monitoring Application Performance on the .NET Compact Framework Part IV - Version 2 performance counters (Part II: Generics counters)
Monitoring Application Performance on the .NET Compact Framework Part V - Version 2 performance counters (Part III: Locks and Threads counters)
Monitoring Application Performance on the .NET Compact Framework Part VI - Version 2 performance counters (Part IV: Garbage Collector counters)
Monitoring Application Performance on the .NET Compact Framework Part VII - Version 2 performance counters (Part V: JIT Compiler counters)
Monitoring Application Performance on the .NET Compact Framework Part VIII - Version 2 performance counters (Part VI: Exceptions, Interop and Networking counters)
The following table lists all of the performance counters available in version 2 of the .NET Compact Framework. The counters highlighted, in yellow, are the ones I will be talking about today.

The statistics file includes running totals, the most recent value (last datum), count (n), average (mean), minimum and maximum values for the counters. I've included an example file at the end of this post. For counters where a given column is not relevant, a hyphen (-) is logged.
I will use the following format to describe each counter.
Counter name
Brief description of the counter
Discussion of the contents of relevant columns (total, last datum, n, mean, min, max)
Any additional comments relating to the counter
Windows.Forms Counters
The Windows.Forms counters provide details on key objects created by forms based applications.

The number of controls (ex: Button) created by the application.
total: Running count of controls
Brushes Created
The number of Brush objects created by the application
total: Running count of brushes
Pens Created
The number of Pen objects created by the application.
total: Running count of pens
Bitmaps Created
The number of Bitmap objects created by the application.
total: Running count of bitmaps
Regions Created
The number of Region objects created by the application.
total: Running count of regions
Fonts Created
The number of Font objects created by the application.

Graphics Created (FromImage)
The number of Graphics objects created via the Graphics.FromImage method.
total: Running total of Graphics objects created
Graphics Created (CreateGraphics)
The number of Graphics objects created via the Control.CreateGraphics method.
total: Running total of Graphics objects created

That's all of the counters! Thanks to everyone who stuck with this series. It was a long road and will (I hope) provide the basis for some interesting future discussions.
Take care,

Will, What you suggest is exactly what I plan to do. Now that the counters have been explained, I will be working on some "case study" style posts.
Thanks!
