Hi Kai, Functions are generally described in http://jakarta.apache.org/jmeter/usermanual/functions.html and http://jakarta.apache.org/jmeter/usermanual/component_reference.html#functions
To use __threadnum do the following 1) create the request object 2) create a param 3) Open function helper dlg 4) Choose __threadNum. This function needs no additional parameters. 5) click generate 6) copy what it generates and paste it as a value to sampler param. It should look like ${__threadNum}, nothing more nothing less... Another functions are used in similar way, you need to fill only requested fields in helper dialog. Referencing to the result of a function in following requests is a bit tricky, it depends on functions and I personally saw no documentation about this. For example to refer to previous regex result, matching group one, named for example id, you should write ${id_g1} (for further reference check in this mailng list archive and if that fails, ask on this list) best regards Michal Kostrzewa -- To unsubscribe, e-mail: <mailto:jmeter-user-unsubscribe@;jakarta.apache.org> For additional commands, e-mail: <mailto:jmeter-user-help@;jakarta.apache.org>
