![]() ![]() Clicking on a date, process, program ID, operation, path, or additional detail will allow you to include or exclude that specific parameter in your filtering. Each task is presented in an exhaustive manner, allowing users to analyze its events, processes, stacks, when applicable.Īs mentioned before, such a tool could prove to be especially handy when troubleshooting a faulty process or unstable operation in your system, and the filtering capabilities at hand serve to further that. Practical to the coreįirst off, the amount of detail that is featured in the main interface might seem quite daunting, but when looking to troubleshoot an issue, such information is most welcome: name, operation, program ID, its path, as well as additional details are given for each entry. Acting as Microsoft's more advanced solution for system monitoring, this offering provides a more thorough overview of your processes, while allowing for tighter control over managing them. The built-in Task Manager is fine for most uses, but if you want something more comprehensive, you might be enticed by Process Monitor, which is incidentally from the same developer. I hope you find the tool useful, feel free to leave comments and bug reports on the Github repo.Not every computer user manifests interest in monitoring their running processes, and even then, who regularly sits around looking at their Task Manager to analyze their running processes? Still, for the times when you do need to look through those processes, it's nice to have a tool ready to support you with this duty. With a wealth of information there is a necessity to be able to filter, find and analyze the results. ETW traces can be captured and analyzed with a myriad of tools, such as PerfView, Windows Performance Recorder / Analyzer, and others. This is naturally a work in progress, but it’s important to emphasize. Additionally, I am trying to get a comfortable and powerful UI to filter, view and inspect information. ETW has an inherent delay of one to three seconds when reporting events, which is not a big deal for this kind of tool, since the events are still ordered correctly and have correct enough time stamps (if using the same ETW session).Īll this means is that ProcMonX sacrifices some accuracy and in some cases pieces of information to get in exchange a huge arrange of events that could not be possible with ProcMon. Hooking with a driver is always more reliable and accurate. Is it better than using kernel drivers? Not generally. The event data is displayed as they come in. ProcMonX creates a real time session (no automatic logging to file) and registers for the events the user requests (the current list is small, more events will follow in subsequent versions). To get a sense of the number of providers use logman query providers in a command window. Windows provides many providers out of the box, each exposing a rich set of events. These events can be logged to a file (.ETL extension) and then analyzed, or alternatively logged in real time to listening consumers. In ETW, providers spit out events that ETW consumers consume. ProcMonX, on the other hand, uses Event Tracing for Windows (ETW), a diagnostics and logging mechanism that existed since Windows 2000. Other types of operations such as memory allocation events is nearly impossible to get since these cannot really be hooked. For example, to get network related events, one would have to write some sort of NDIS filter or perhaps use the Windows Filtering Platform (WFP), both of which are far from trivial. With this approach, adding new functionality is really difficult. File system operations – Use a file system mini filter, to hook pre and post file system operations.This is how ProcMon knows how the operation completed. Every possible registry operations can be hooked – before the operation and afterwards. ![]() Registry events – Use the CmRegisterCallbackEx function to register callbacks for pre and post operations.Image loading/unloading – Use the PsSetLoadImageNotifyRoutineEx to register a callback for such notifications.Thread creation/termination – Use the PsSetCreateThreadNotifyRoutine function with a callback invoked for every thread creation or termination.The full command line is available to the callback along with creating thread/process. Process creation/termination – Use the PsSetCreateProcessNotifyRoutineEx function to hook process creation and termination.Here is a list of events and the way ProcMon gets to the data (I have not actually since the source code, but that’s how I would have implemented it): The upside to using a driver is the ability to get the most accurate data, since some form of hooking is involved.
