Has anyone used Threadmaster in a non-TS environment? I have one client
back-end server where every so often *something* gets out of control -
can't track it down. This server runs Exchange, AV, Fileserver, backup,
DNS (I know, too much), so it's probably some weird interaction.I am
imagining that if I put Threadmaster in and set it to, say,50%, it will
ameliorate this behavior. Or is it only competent for TS type
environments? And does it understand Hyperthreading?

Hi Kyle,
TSadmin is dependent on appropriate reporting from the TS
servers hosting the application instances. If the application has hung
and is using excessive system resources, then the reporting can fail.
If the application difficulty the users were having is that the
application doesn't respond, then I wouldn't be terribly surprised at
what you are seeing.
I guess that's the bad news.
The good news is that if you use a CPU control application
(Appsense perfomance manager, Armtech, TMUlimit, TScale, or Threadmaster
[free]) you'll find that not only will system performance and stability
improve, but application stability will improve as well.
An example I can give is one of our sites where they had chronic
problems, with people using huge spreadsheets or powerpoint
presentation, a excel and powerpoint instances locking up and chewing up
100% of a CPU. Once we were conrolling CPU utilization, the application
lockups have become a rare rather than a daily occurrence.
It's made me realise that there are functional as well as
resource benefits to restricting application CPU usage.
Depending on your budget, try a trial copy of TScale or
Appsense, or download and install Threadmaster. THreadmaster is pretty
darn basic compared t the other products, but the price is right and
it's heaps better than nothing.
regards,
Rick

Subject: [THIN] Users missing from TSadmin
Hello,
Recently I have encountered an interesting issue in TSadmin. I
have received two calls this week from 2 different users who were
connected and working inside of our published apps, but they were not
visible in TSadmin; and we need to shadow them as they encountered
difficulty in using the apps. I had them verify that they were
connected to a specific server in the farm(used the ICA icon in
systray), and checked/refreshed the server(s) many times but they would
not appear in the list of users. Both users in question hit multiple
servers in the farm, but were not visible at any time on any server.
They are set up the exact same way as the other users, to my knowledge
... but I could be overlooking something. We use Win2k (SP3) servers
with Citrix XPE FR2.
Has anyone ever previously encountered an issue like this? Any
and all assistance is greatly appreciated.
Thanks,
Kyle
