pdh.dll - What is pdh.dll?

pdh.dll File Description:

The Performance Data Helper (PDH) makes life a lot easier for users and programmers who want to acquire performance information and monitor the capabilities of Windows NT. The module pdh.dll contains all the functions that any programmer can rely on in terms of generating performance data structures without the need to write lots of codes to get performance information.

The Windows NT was designed to have its own performance-monitoring capabilities. Native performance data can be acquired by wading though performance data structures that require codes to be written by the programmer. When the PDH library was introduced sought to enhance the performance-monitoring capabilities of Windows NT by simplifying functions to acquire performance information. The module pdh.dll contains program codes that can be used for the creation of log files and other measurement methods. By calling. on the pdh.dll file, data is packaged and made available to the programmer.

What is good about the PDH library is that it provides an easy-to-use dialog box that allows users to select counters interactively. It thus makes the work of building a performance monitoring program much less complicated. The pdh.dll file packages the data coming from Registry functions to create a counter. While the programmer needs to perform calculations of raw data in order to get the information from a counter, the pdh.dll file instead does this for him or her. The programmer can utilize the dialog box provided by the PDH library simply by specifying counters as strings. It should be noted that there are around 30 different types of counters that a performance data contains, and as such there are 30 different ways to calculate the information. Being saved from this enormous task alone makes the PDH library a worthwhile function for the programmer.

The PDH functions use prototypes and structure definitions that come in two header files. In order to gain access to the functions, data types, and structure definitions used in the PDH library, the header 'PDH.h' should be included.

Similarly, other PDH functions are made available by the pdh.dll module, which provide connection to remote machines. It also supports native performance capabilities of Windows such as enumeration of performance objects, counters, and instances of an object. It gets counter information and also sets scale factors of the performance data.
