![]() If the altitude is not what you set and you did not restart the machine, please restart your machine. If not you should be able to just start procmon.įrom an elevated command prompt, run the command “fltmc instances” and verify that the procmon drivers are running at the altitude that you set. If you have already started procmon before doing these changes, you will need to restart the machine. You will have to uncheck “inherit permissions” in order to be able to set them at the Process Monitor Instance level. Reason being that procmon will try to change its value back right away. If you are not a UCD student and have not applied previously, you must register before using the system for the first time. You must also set the security on the “Process Monitor xy Instance” key and add deny rights for everyone for “delete” and “set value”. Ĭhange the Altitude value to lower than your driver altitude. Run regedit and navigate to registry key. This key location can change with each version of Procmon. There is a separated version for 圆4 applications. It’s free and portable, works on all Windows platforms. The fllowing steps assumes that the ProcMon registry data lives in a floder called PROCMONxy. It monitors the changes and creates a standard RedEdit registry file that contains all the registry changes made by the selected application. We can change the altitude of procmon with fllowing steps. We can get other allocated altitude in document Allocated Altitudes. In doing so we will be able to see all of the activity that we want from any filter driver.īy default, the altitude of procmon driver is 385200. So if you need to get Procmon’s filter to run below Low level Driver in the filter stack, we can lower the altitude of procmon driver, putting it lower in the filter stack. If you’d like know how to perform IIS error tracing for your Windows web servers, feel free to contact us.Procmon is usually used to show real-time file system, Registry and process/thread activity, but you do not get to see the activity of things such as virus scanners and unifiltr because they happen at a lower level than the procmon filter.Īs we know,every minifilter drier must have a unique identifier called altitude, which defines position relative to other minifilter drivers in the I/O stack when the minifilter driver is loaded. The Process Monitor (ProcMon) tool is used to track the various processes activity in the Windows operating system. Using Regshot to Track System Changes Now that you have installed regshot, you are ready to put it to the test. Right-click on the relevant event, and select properties to see the reason for the error. It is best to open it as an administrator by right-clicking on the appropriate file and then selecting the Run as administrator option. You can see a list of what and all happened during the time when the site was accessed. Once the loading of webpage is done, turn of “Capture”Ĩ. Keep the website you want to trace ready in the browser.ħ. Turn off “Capture” (Ensure the Red Cross mark on the Capture icon)Ĥ. Customize your filter options based on the error you are investigating.ģ. You can monitor changes to Registry by using the command-line File Compare fc.exe tool or freeware like WhatChanged, RegShot, Sysinternals Process Monitor, etc. How to use process monitor to capture the eventsĢ. ![]() You can either use the “Drop filtered events” option to capture only the events you want, or just run the capture for a very short time as explained below. Note: It is very important to note that Process monitor is resource hungry! Never leave the “Capture” ON with the default settings as this could easily lead the server to go down. Now, right-click on the event, and select “Properties” to find out exactly what’s causing the error. The log will then display which process tried to access the file. It has a convenient filter option, which you can customize to focus on only those events related to the domain or status you are investigating.įor example, if you have an “Access is denied” error, put a filter on the domain file path, and further focus with the status. Process monitor can be used to capture what happens in the back-end when you access a web page in the browser. Process Monitor is an advanced monitoring tool for Windows that shows real-time file system, Registry and process/thread activity. ![]() The IIS errors may not be very descriptive, and the log files may not contain all necessary information.įor such cases, we use Microsoft Process Monitor to exactly pin point what is causing the error. We’ve seen that, in Windows dedicated servers and VPS, users sometimes request assistance in troubleshooting HTTP errors. In our role as Outsourced Tech Support for web hosts, trouble-shooting and maintaining IIS web servers is something our engineers do on a regular basis.
