http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/apimon-o.asp Apimon.exe: API Monitor This tool monitors a running application for all Application Programming Interface (API) calls a process is making. APIMon counts and times the API calls. It also, optionally, monitors page faults caused by the monitored application and reports them by API call.APIMon is useful as a performance monitor to help tune your application. You can determine the hot spots in an application by examining the APIs with the largest times and/or counts. You can look at which APIs are used, taking special note of calls that cause ring transitions to kernel mode or client/server transitions. Large numbers of these calls can be the cause of a slow application.APIMon can generate two types of reports.A report listing the number of calls made to each API and total time spent in each API. A trace file listing the individual calls to all APIs with the calling parameters as they occurred in time.
