Task scheduler

Is there something like that in AmigaOS4?

I wonder if it is possible to track running tasks and show which one is using up what amount of ram/cpu.

@Raziel

SysMon displays a list of running tasks.

@daveyw

CPU docky in ztools as well.

Thanks guys

Unlike the old AmigaOS <= 3.9 one the AmigaOS 4.x ExecNG task scheduler does record the CPU usage times of the executed tasks.
I don't know if tools like SysMon, Scout, etc., can display it, but I implemented a "top" like, shell-only tool several years ago which did.
IIRC I never did a public release of it and it was only available on the internal OS4 developer/beta-tester FTP server, but in the unlikely case it's still working (very likely doesn't work with beta multi-core kernels) it's OK to upload it to os4depot.net if one of the former OS4 developers or beta testers still has it.

I've checked in the beta ftp but doesn't seems it is there. Do you remember the name? Because that server is a mess

Joerg has sent this tool on beta list (Aug 1st 2008).

I can send this to Joerg and he can release it, or I can upload it somewhere with a license, if needed.

@joergQuote:

Haha, looks like you buried the lead there...

It's still working for me on the latest beta kernel (not running the multi-core one though).

However, it doesn't seem to have any version string, and doing a C:Version on it made my system lock up. So don't do that .

The main functionality is apparently okay.

One piece of info for anyone using it: Use Ctrl-C to stop the auto-updating display and end the command.

Best regards,

Niels

@joerg

Does the source to your tool also still exist?

It would be awesome to get this kind of information into existing GUI based tools/duckies

Thank you

I have been wondering for years why there is no tool to display cpu usage of each task and then it turns out that there's been one out all the time (i think i got my first os4 machine in 2008)

Please anyone upload it asap.

@nbache

Could you see also task names? Didn't ExecBase struct change recently, IIRC task lists are private now.

What is the tool name? Because I don't find it.. and 2008 email are on the AmigaOne HD that I don't use anymore..

@Raziel

I would think i have a copy of the sources somewhere, if Joerg agrees and doesn't have a copy i can upload it somewhere myself.

@Ami603

I may still have the sources in some old backups, but nothing I can access currently. You can release it if you want, but if it's working the way I think it did it it could be that it requires internal exec includes not part of public SDKs (struct ETask).

I found several different top.lha in the OS4 beta mailinglist in my Thunderbird backups between 2006 and 2008, but even if they have the same name, and as Niels wrote no version strings, they may work completely different. At least the oldest versions couldn't use the CPUs usage timer from ExecNG in struct ETask yet, it was an ugly hack using interrupts instead...

@joerg

Here is a version from 2008:

@nbache

I haven't downloaded Capehill's version, but mine is:
