You can also create a dump of a process for later analysis with tools like WinDBG: These allow you to configure Process Explorer to Run at Logon, Send the executable hashes to VirusTotal for verification (if you’re suspecting malware infection on the machine), Replacing Task Manager with Process Explorer (though I’ve had less than stellar success with that option on particularly problematic machines) and configure Symbols, which we’re going to look at further down in the article. On the top of the bar there is a menu with many different options, but the really interesting ones are these: You can get additional information about the process by putting the mouse cursor on top of it, and it even shows the services running within a svchost.exe instance: All of these columns are fully customizable to fit your needs: NET processes, “Immersive” processes, suspended processes, processes running as the same user as Process Explorer, processes that are part of a job, and packed images. Additionally, you can see the path to the executable and color coding that identifies the process type and state, such as services. More on that later) and much more.Īs you can see Process Explorer presents columns detailing running processes on your system, including the parent/child relationships, CPU usage, memory data, PID, description, company name, certificate signature, and verification status. It shows detailed information about all the running processes on the system, including resource utilisation (GPU, CPU, Memory, ecc…), Path, Signature, Threads and Stacks (though for a clear view of the stacks Symbols have to be configured and WinDBG installed. Process Explorer is, as Mark Russinovich calls it, “Task Manager on Steroids”. Let’s start with a short instruction about these tools. In this blog post we’ll focus on Process Monitor and Process Explorer while Autoruns and Procdump will be covered in the next one. The Sysinternals suite of tools is a collection of over 70 utilities that can be used to troubleshoot and diagnose a wide range of issues on a Windows system. Now that we’ve gotten the Russinovich mantra out of the way, let’s delve in! It is also possible to save the the whole trace with callstacks as text (File/Save, choose XML, include callstack + resolve callstack).And here we are on the 2nd post: Introduction to Process Explorer and Process Monitor.īefore we start, repeat after me “When in doubt, run Procmon!” This is what I see after clicking on the first event of my tracing session (corresponds to opening my.ini file) Once symbols are configured, you'll get a stack trace corresponding to a filesystem event by simply doubleclicking on the line corresponding to the event. (substitute last last path element with real path to your installation) On my system it isĬ:\Program Files\Debugging Tools for Windows (圆4)\dbghelp.dll Add dbghelp.dll from your installation of Debugging Tools into "dbghelp.dll path" input field. Switch to Process Monitor's menu Options => Configure symbols.ģ. Install Debugging Tools for Windows (google on how to do that).Ģ. For this to work, symbols support needs to be configured. It is also possible to see stacktraces corresponding to the events. (Advanced) Seeing stack traces corresponding to events Mysql> install plugin blackhole soname 'ha_blackhole.dll' īack to Process Monitor Windows, you should see the filesystem events initiated by the "INSTALL PLUGIN" operation Start mysql command line client and connect to the server. Capture events (Menu File=>Capture Events (Ctrl+E)ģ. Use this dialog to set filter to "Process name" "is" "mysqld.exe", as shown in the screenshot below.Ĭlick on "Add" button to mysqld.exe to include it in the filter, "Apply" and "OK".Ģ. Dialog will pop up that offers to set filter. We assume that mysqld.exe is already started.ġ. The purpose of the following exercise is to learn how to use procmon to trace mysqld.exe calls to the filesystem. I suggest putting procmon into some directory in the PATH environment variable. There is no installation necessary the single executable can be used after unpacking. More description can be found at https: /en-us/library/bb896645.aspx Installation Process Monitor can be directly downloaded from. It is a part of sysinternals suite developed by Mark Russinovich and Bryce Cogswell. Process Monitor is an advanced monitoring tool for Windows that shows real-time file system, registry and process/thread activity. This article provides a walkthrough on using the Process Monitor on Windows, tracing file system access by mysqld.exe during the "install plugin" call.
