Overview
statlist: A PDH Demonstration Program

Statlist is a demonstration program to illustrate how the PerformcnceData Helper (PDH) library can be used to collect performance data anddisplay statistical summaries of that performance data.

To view system performance data with Statlist, you must first selectone or more performance counters to monitor. Counters are added by selectingthe Configure Menu Item, then selecting the Add Counter... menu selection. A dialog box will then display all the counters available on the system. Select the desired performance object and counter, then press the OK button to add that counter to the list in the mainwindow.

To obtain the current data for the counter(s) that have been selected,simply click the Get Data! menu selection and the current data valuewill be displayed in the window along with all the updatedstatistical values.

Note: that only the last 100 samples are used in thecomputation of the statistics.

Get Data!

Obtains the current value of all counters in the display from the systemand updates the display with the current data and the current statisticalvalues. If more than 100 samples have been collected, the statistics represent only the 100 most recent samples.

Note: If a counter has been added that is the same as one already inthe list, it may take several data samples for the "last value" of each to agree. This is due to the fact that many counters are differentiated overtime and the time interval of the existing counter will be different thanthat of the newly added counter until several samples have been taken.
