Using 3.0.855 and the latest stable release the column called Disk write bytes only provides data for "System" process, all the other processes are black.
Why? How can I fix it?
Not sure. Have you tried rebooting or manually resetting the etw provider?
1) Exit Process Hacker
1) Open Computer Management
2) Select the Performance > Data Collector Sets > Event Trace Sessions
3) Locate the following entries:
4) Right-click both entries and select "Stop" then right-click again and select "Delete"
5) Restart Process Hacker.
Let me know if this fixes the issue
Another error I get when I don't disable avast self protection is this:
Unable lo load kernel driver. A device which doesn't exist was specified
The kernel driver is a critical security component required to support a number of Process Hacker features including process information, detecting malware and even removing rootkits... Previous versions of Process Hacker never warned the user when the driver failed to initialize and malicious software exploited the lack of error messages to secretly block and interfere with our kernel driver.
Avast has been blocking our kernel driver for several months and refuses to discuss the issue with the development team... All future versions will now show various error messages when something blocks or interferes with our kernel driver and in your case Avast blocked our driver resulting in the error dialog.
You can change the EnableKphWarnings setting in the settings file if you don't want to see these warning dialogs but I highly recommend leaving them enabled for increased security and taking up the issue with the developers responsible for interfering with our driver.
