I like something that can take any code block and wrap it with stopwatch profiling code to measure time spent executing it: using System.Diagnostics; using System.Threading; public static T Profile
c# - What is the correct Performance Counter to get CPU and Memory ...
For anyone still landing here, I want to piggyback on what @Quantic was saying about the values of the counters. As detailed here, the Processor (% Processor Time) counter will be out of 100 and will give the total usage across all processors/cores/etc in the computer. However, the Processor (% Process Time) is scaled by the number of logical processors.
Creating Custom Performance Counter in C# - Programming Examples
1. Introduction to Performance Counter & Monitor. Perfmon is a windows tool, and it is useful to monitor ‘System’ and ‘Application Performance’ by measuring various parameters and plotting it as a graph. The measuring parameter is called ‘Performance Counter’.In this example, we will add our own Performance Counter that tracks the UI activity of our sample application.

What is performance counter?
Then we can diagnose problems and fix them in the future. Performance counters enable us to publish, capture, and analyze the performance data of running code. A performance graph is a two-dimensional plot with one axis indicating time elapsed and the other reporting relevant relative or actual performance statistics.
What is the complete C# programmers guide?
The Complete Visual C# Programmer's Guide covers most of the major components that make up C# and the .net environment. The book is geared toward the intermediate programmer, but contains enough material to satisfy the advanced developer.
How should performance counter data be stored?
Since performance counters are not persisted in SQL Server, it falls to a developer or administrator to regularly poll dm_os_performance_counters, collect metrics, and store them in a permanent location.
What is a table created to accept data from dm_os_performance_counters?
With a table created to accept data from dm_os_performance_counters, a process can be built that regularly collects the data and stores it here.

What is SQL Server performance monitor?
SQL Server performance monitor data is a vast set of diverse metrics that provide a window into many areas of SQL Server performance. To get the most out of this data, it needs to be collected, stored, and maintained over a long period of time. This article explains a method of collecting SQL Server performance monitor data.
How to calculate counter rate per second?
The counter rate per second is calculated by dividing the amount that the counter incremented by since the last sample by the number of seconds since the last sample.
How many rows per counter per sample?
The data can be stored in a similar fashion as it is returned in the view: one row per counter per sample, but I personally find it far easier to work with this data when it is pivoted so that there is a single column per counter per sample. It creates a smaller data set and one that benefits more from compression and columnstore indexes.
What is the value of customizing data and usage?
The value in a process like this is versatility , and by customizing the data and usage, a developer or administrator can learn a great deal about their database servers and the underlying databases. No single set of metrics applies to everyone and by tailoring a data set to an organization’s specific needs, an ideal set of data can be maintained that allows for database servers to be effectively analyzed and planned for over time. As conditions change, metrics can be added or removed, ensuring that even as data evolves, the ability to understand it is not compromised.
Can you add a database-scoped counter to a table?
While no database-scoped counters were included in the examples above, they can be added via similar processes. If the number of databases to be tracked is small and finite, then adding them to the tables already presented here makes sense. If the number of databases is large or variable, then creating a separate table for them is a more scalable solution.
