Re: flood random profiletype?

[Skye Poier Nott]

Well if it helps, I'd love to see this in the SVN head branch sooner rather than later.

Please hear my prayers, powers-that-be :)

Thanks

Committer-folk: see how popular this would be?

Even better - very cool patch!!  Like many people, I'm interested
primarily in simulating real world traffic and round_robin doesn't
really cut it.

So is it in SVN or... ?

It works a bit differently because it does text substitution.
That's a
more general case and is much more common for our needs.  Here's how
it
would work in your case:

1.      use a requesttemplate
2.      the URL would be http://w${RANVAR}.example.com/file.html
        RANVAR is the substitution variable, you can pick your
        variable names and have more than one in a URL
3.      create a substitution file containing lines with the text
        you want substituted as (example file name mysubstfile):
        0000\n
        0001\n
        ...
        9999\n
4.      Have a config file with a subst_list entry like this

        <subst_list>
                <subst_entry>
                        <subst_var>RANVAR</subst_var>
                        <subst_file>/path-to/mysubstfile</subst_file>
                <subst_entry>
        <subst_list>


The win is that the subst file can contain lots of things beyond
random

get very good agreement with your actual traffic.  So URLs like
http://example.com/?q=${QUERYFROMREALTRAFFIC} work fine.  You can do
port numbers too.

Very large subst files work fine.

Interesting..

I have 10,000 host aliases setup up from w0000.example.com to
w9999.example.com so your patch would let me do something like
http://

Well that would sure cut down on the size of the flood config xml.

Hopefully your patch can do zero padding of random numbers!  What's
the url for the patch file?

Thanks,

w{random number from 0000-9999}.example.com/file.html in the urllist?

Actually, I think my current patch which does randomization on
URLs in
round_robin profiles provides a bit more.

Any news on the patch, folks?

It looks like (contrary to the docs) the only available
<profiletype>
for flood is round_robin.

Does anyone have a patch to support <profiletype>random</
profiletype>?

If not, and I write one, would you be interested in the patch?

Thanks,
Skye
