Hello,
I don't think, scripting is a good choice. Last year I used Tcl scripts for creating JMX, this year I'd have to write new scripts. File format changes.
I'm neither convinced of the "evil suggestion". It's not intuitive. It's reusing features build for other purposes. It can't reconstruct the change between HTTP and HTTPS. And and and...
If I find time, I'll do my homework, present a ready patch and ask again.

Or - continuing the theme - use a scripting language to create the JMX file.
This becomes a lot easier with the work that Mike has done on using Xstream for parsing the file, as the JMX file format is now a lot simpler.

Evil suggestion:
Use the current AccessLogSampler on the list of urls (may need a new parser implementation, depending on format of list).
Run two instances of JMeter. One instance has a recording proxy server on. The other instance is started up to USE that proxy server. This second instance runs the AccessLogSampler against the file. The samples will then be recorded in the JMeter running the proxy server.

ok, I think I understand now. To paraphrase.
1. import in URL via some mechanism 2. manually change the threadgroup to simulate user session 3. run test
it sounds like you would like a better solution to 1 and 2 using some sort of import. correct me if I'm wrong. the feature you are looking for is something like this.
1. a file of URL's with multiple sets of request parameters 2. use a new plugin to import the file 3. the plugin generates a thread group with n HttpSamplers matching exactly the same number of parameter sets in each line. Like say each line does login, search and logout. the import would create three HttpSamplers with the correct parameters in each. 4. run your test plan.
Is that an accurate interpretation?

Hello Peter,
thanks for the reply. I definitly should have a closer look at the
access log
sampler. Let me explain further, what I would like to get by an import
feature.
If I get individual samplers by importing a list of (HTTP-) addresses, I
can
configure requests much more precisely. In my case I need to simulate
half a
dozen different users, who are subscribing to newsletters, login,
logout,
ordering products, registering etc. I need to url-rewrite nearly every
request,
iterating over productlists, address-lists, accounts etc. The import
itself is
only the first step in building the test plan for me.
If I am not focussing on server logfiles, I may also switch between
different
protocols, samplers, even server instances. I had the idea of stress
testing a
server by a combination of webservices- and user-requests; first I'd
have to
import SOAP requests and the usual HTTP requests, afterwards combining
them to a
complex test plan. Ok, I'm not sure, if such a scenario makes sense at
all;-)
And last but not least a practical reason: As a customer, whishing
someone to
check my site, I would copy-paste URLs from the address line of my
browser to a
file. I actually got my linklist as a power point presentation :-)

Mike recently made a lot of nice changes to AccessLogSampler. Probably the easiest way is to write a parser that implements the parser interface. then you can simply drop the jar file into /lib/ directory to use it with the AccessLogSampler.
the original idea behind the accesslog sampler was to use production access logs for simulating loads and running simulations. This is particularly useful if there's a bug that appears under very specific situations. Say you discover a bug in a webapp, so you stress test it. The bug doesn't appear with randomly generated requests.
in cases like these from my own experience, it is the result of usage patterns, which random requests can not reproduce. the accesslog also lets me compare one system to another and make apples-to-apples comparison. well as close to apples-to-apples as possible. if you need help implementing the parser interface, just post a message and I'll try to explain it to the best of my ability.

I just started to prepare a jmeter add-on to import request lists, using each request parsed from the list to create a sampler suiting the protocol. But may be I'm overlooking an allready existing feature? (As far as I can see, the access log parser has a much more specialised - and different - idea.)
Until now I'm focussing on linklists / clickstreams. The import parses a list of links (seperated by linefeeds) and creates a HTTP sampler (as a child of the current node) for each of them. It's taking care for preserving the protocol (which only can be HTTP and HTTPS until now), server name, port number, path and parameters (using HtmlParsingUtils.createUrlFromAnchor()).
Background: I had to build a test plan by 79 requests, the clickstream file has 13792 characters, http parameters everywhere. Especially to paste parameters is extremly error-prone.
I inserted this import function as a menu point in the file menu, - it's just opening a file-open dialog.
Is there allready a better way for doing this?
