![]() ![]() Take, for example, the scenario I described in my recent post on improving the performance of merge operations. Process Monitor, a free tool from Microsoft, allows you to monitor file system activity in real-time and even having spent a limited amount of time using it I can already tell that it can provide a lot of information to help identify performance issues with file-based data sources. With relational data source like SQL Server you can use tools like SQL Server Profiler to see the queries that are being run by Power Query, and I blogged recently about using Fiddler to troubleshoot OData performance issues but what about file-based data sources, which often present the most challenges regarding performance? Process Explorer is available for free download separate from the suite.Troubleshooting Power Query performance issues in Power BI and Excel can be difficult because it’s a bit of a black box: there’s nothing in the UI to tell you what’s going on inside the Power Query engine and the diagnostic logs are very difficult to interpret. Process Explorer was one of many tools created by Winternals Software, which Microsoft then acquired and renamed Windows Sysinternals. ![]() IT can add the VirusTotal column in options, and the column will show all the antivirus sites that flagged a process as a potential virus. Process Explorer also uses VirusTotal to monitor potential malware from questionable processes. IT can easily locate files that get locked or lost in the sea of processes in the handle view. Hitting the space bar pauses the automatic updates so IT can monitor a process closely before it disappears. The tools in Process Explorer offer targeted help such as Fast Search to locate a file quickly or the Kill Process option to shut down a complete process tree with one click. The modes are specific to the type of data Process Explorer displays, so if IT wants to see a DLL-version problem, then Process Explorer should be in DLL mode. Handle mode shows integer values used as identifiers, or handles, for the active processes and their threads, while DLL mode shows the DLLs and memory-mapped files that the process has loaded. The bottom window provides a zoomed-in look at the Windows processes, and it changes depending on what mode Process Explorer is in. The tool has an area that shows all dynamic link libraries ( DLLs) and handles, icons, command lines, full image paths, memory statistics, security attributes and more. Process Explorer's top panel has line charts, color codes and symbols IT can customize, as well. Likewise, IT professionals can organize the rows alphabetically or numerically. IT can customize what information the columns include based on preference. The processes are set up in a hierarchical view with parent processes on top and child processes beneath them. The top window shows a real-time list of active processes, a description of what the processes are doing, the CPU and memory usage, and the software company name. Process Explorer has two windows of colorful information. It is part of the Sysinternals Process Utilities suite, which has a selection of tools to give IT more control and options for better Windows performance. Process Explorer provides more visual, in-depth reports than Windows Task Manager. Process Explorer is a free Windows task manager and system monitoring tool that details which programs in a user's system have a specific file or directory open.Īnyone can download the utility for free from Microsoft. ![]()
