Re: Question about Olio/Faban

[Akara Sucharitakul]

I checked real quick for the behavior of the variable load and with the 
current source, I don't think this behavior would be there. The threads 
get started and notifies the master before it goes into the load 
variation so you should not see the log sequence as you send me before. 
Can you check whether you have an older Faban build? If so, can you 
please upgrade to 1.0RC1 (on http://faban.sunsource.net/).

As for results, the final results will not tell you much. You should 
rather enable the runtime stats in your run confirguration file. Search 
for <runtimeStats enabled="true|false">. It will periodically dump out 
the current stats into the logs (I know this also needs improvement). 
Thanks.

I'm curious as to whether the final figure/data will capture the variable workload or 
just ramp up -> steady state -> ramp down data.

I'm interested in the response time graph of the variable load.

Let me take a look at it. The feature
needs a lot of work anyway. Will 
take some time, though.

Hi Akara,

I did what the doc said but I'm getting a weird
behavior.
My run.xml looks something like this:

<fa:runControl>
<fa:rampUp>60</fa:rampUp>
<fa:variableLoad>true</fa:variableLoad>

<fa:variableLoadFile>/root/faban/config/profiles/test/variableFile</fa:variableLoadFile>
<fa:steadyState>3600</fa:steadyState>
<fa:rampDown>60</fa:rampDown>
</fa:runControl>

My variableFile: 
1200, 300
1200, 400
1200, 500



The behavior I'm getting is Faban runs the variable
load first, then after running the variable load, it then
starts ramping up->steady state -> ramp down.

Yes, but the feature is still quite
restrictive. We're building it out better in the
future.
Please see how to do it here. Let us know if you
run into
problems.

Adding yet another Faban instance altogether will
cause
conflicts.

Hi All,


Is it possible in Faban to increase the number
of
concurrent users in the middle of the run? If not,
is it
possible to run 2 Faban instance (maybe on
different
machines) and run the other benchmark run after
the first
one is running a while? Will it cause any problems
on
the  faban agents side if 2 instances are
talking to
it?
I'm interested to see how the response time
behaves/pattern when the number of concurrent
users change.
Thanks,
Harold
