flood random profiletype?
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

Yes, it has to be a requesttemplate. That allowed it to be a relatively
small patch.
Thanks for trying it.

One thing I've noticed is it doesn't seem to do substitution if you
specify:
<url>http://${hostname}.example.com/index.html</url>
but if I use this it works fine:
<url method="GET" requesttemplate="http://${hostname}.example.com/
index.html" />
I'm not sure if that's intentional.
Anyway, seems to work great, thanks again!! Very useful!

I submitted it as unix text. Well, I'm glad the patch applies. Let me
know of any issues.

Nevermind, it works fine. The patch attachment I downloaded from the

even though I'm on a BSD box :P

I did it against an svn checkout from that date, or very close to it.
Can you show the actual errors? or a few?

Great, thanks for the link.
Is there a specific tag I should apply the patch to? I'm getting a
lot of patch failures applying against HEAD and even the 2007-12-19
version of files (a frequent date in the diff). eg:
Patching file flood-orig/flood_round_robin.c using Plan A...
Hunk #1 succeeded at 55 with fuzz 3.
Hunk #2 succeeded at 117 with fuzz 3.
Hunk #3 succeeded at 132 with fuzz 3.
Hunk #4 succeeded at 185 with fuzz 3.
Hunk #5 failed at 238.
Hunk #6 failed at 752.
Hunk #7 succeeded at 874 with fuzz 3.

At the moment it exists as an attachment to older mails of Guy to the

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

Well, no, because it's been submitted but not approved. But you could
ask that it be approved! There needs to be a discussion about it, there
is one tradeoff in the algorithm that needs to be understood.
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... ?

Re: flood random profiletype?
Posted by Guy Ferraiolo <gu...@cnet.com>.
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${RANVAR}.example.com/file.html
RANVAR is the substitution variable, you can pick your
variable names and have more than one in a URL
3. create a substitution file containing lines with the text
you want substituted as (example file name mysubstfile):
0000\n
0001\n
...
9999\n
4. Have a config file with a subst_list entry like this
<subst_list>
<subst_entry>
<subst_var>RANVAR</subst_var>
<subst_file>/path-to/mysubstfile</subst_file>
<subst_entry>
<subst_list>
The win is that the subst file can contain lots of things beyond random
numbers. It's very easy to create a subst file from an access log and
get very good agreement with your actual traffic. So URLs like
http://example.com/?q=${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://
w{random number from 0000-9999}.example.com/file.html in the urllist?
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,
Skye

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?
