Re: Diagnose high wait

2017-04-24 Thread Harder, Pieter 
Just to give an extreme example from another time, another galaxy. I had a 
z9-BC (I told you, long ago) with TSM Linux VM (Tivoli Storage Manager, the 
backup thingy) that moved data for replication purposes from a TS3500 to a 
TS3310 with six tape pairs. Reached almost 1 GB/s with very little CPU going 
on. You should have seen the wait on that. And yes, I used Barton's tooling to 
look at it together with Rob.

best regards,
Pieter Harder

On top of what Barton said, a high percent wait time can show up if a Linux 
system is using very little CPU time, but one or more tasks are doing a lot of 
I/O.  If the system is using a lot of CPU, then it's more likely what Barton is 
talking about.

Re: Diagnose high wait

2017-04-24 Thread Barton Robinson 

On our website,
"http://velocitysoftware.com/present/flowchrt.html; , there is a
performance analysis flow chart.  When there is wait, it is MOST often
not related to the linux server, it is MOST likely to be related to
resource constraints that the server just happens to be using (cpu,
storage/ram, paging, sometimes I/O...).
There is also a performance class
"http://velocitysoftware.com/seminar/workshop.html; june 19th in
Columbus just prior to the VM Workshop.  Or in the UK Nov 6th prior to
the UK GSE.

That's always the question.  Every time in the past when we've tried, we didn't 
draw very many attendees at all.  The percentage of attendees at every 
conference that are new or haven't been there in quite a while is rather high.  
Those seem to be the ones that want to take our labs.  The same seems to be 
true of our non-lab sessions.  Advanced topics draw very few attendees which is 
hard to justify the next time around.

Given the limited slots we have available for labs, a full-day lab is _very_ 
unlikely to happen.  The limit seems to be three slots these days.

2017-04-24 Thread Michael MacIsaac 
Mark,

OK, but when to we 'raise the bar'?  I was hoping a one-day (or even a half
day) lab could be created to get to a working "Self-service portal" (aka
"Private Cloud").

I'd like to say zoom on top of SMAPI on top of a directory manager would be
adequate for a 'back-end'.  But an open-source Web UI front-end is still
needed IMHO.  It's not a trivial amount of code, but neither would it be
excessively large.

I'm hoping to get to SHARE in August and present on what we have running
internally (if all goes as planned - can't make promises).
