Issue Process List Error

KirkM

Regular Pleskian
Server operating system version
Almalinux 10.2
Plesk version and microupdate number
18.0.79
Going to the Process List in the Plesk Panel shows this error. Notice the extra forward slash in the script path (modules//repair) where either it is a typo or a directory is missing in-between. I assume this is somewhere in the Process List extension code. Bug? Faulty installation? Thanks for any help.

It's stating you don't have iotop installed, which is what the script relies on. You can install it via SSH with the following:
Bash:
dnf install -y iotop

Thank you, that was the issue. So it is a faulty installation of the Process List extension? Wouldn't the extension install all dependencies to properly function? Although this fixes the issue, I am concerned about the root cause of the problem and making sure if there is a flaw in the extension, that it gets reported and fixed.
 
Not really, since it isn't needed for full functionality (only if you care about those numbers) and is pretty common to not see it installed on a minimal installation of the OS itself.

But it appears it is needed for full functionality as the disk data can't be fetched without it and it literally throws an error message in Plesk if you use the extension and go to the panel page to review the data. That really doesn't sound "optional" to me.
