There is a system. Diagnostics namespace in the. NET class library, which provides some class libraries that interact with system processes, event logs, and performance counters. It includes two very useful classes for developers-Debug and trace. This article introduces some basic functions of these two classes to improve the development efficiency of developers.
functions are slightly different at run time: A typical custom Function (UDFs) can be invoked like this:
SELECT column_list
From Owner_name. Udf_name (@parameter1, ... @parameterN)
The system-supplied custom function needs to be preceded by a two colon (::), and you do not have to specify the owner of the feature:
SELECT column_list
From:: fn_systemsuppliedudf
(@parameter1, ... @parameterN)
For example, the syste

When I see the CPU time of I/O waiting time is very high, the first thing to check is whether the machine is using a lot of swap space, because the speed of hard disk operation is much lower than RAM. So when the system is running out of memory, start using swap space. The performance of the system can be severely impacted.No matter what you want to access the hard disk operation is finished with the hard d
Sometimes, it's helpful to trace system api cils during debugging so that we can determine if the incorrect behavior is caused by passing wrong argument to a function or not. or we can try to identify the performance bottleneck with it. there are several tools to use with this purpose.
For demonstration purpose, we'll use code below to try these tools
#include "Windows.h" / "unistd.h"#include "fstream
In Windows, you can also use osw to trace the historical system performance.1. difficult background of Windows System Performance Analysis
In Linux/Unix, to keep track of historical performance, we generally deploy nmon for performance monitoring collection and storage, but it is not in Windows.
For Windows systems, it is always difficult to analyze historical p
