Is there a way to print results from listners? Varibles and datebase problem

Hi

I'm wondering if there is a way to print resuts from listners? 

And also if there is a way to save results directly to file without 
keeping it in JMeter memory. I want to run long period testing(2 days) and 
i don't have enought memory to save such a big result. 

Is there a way to take values for varibles from datebase? Not only for one 
but for all in User Parameters. For only one it would be easy to write 
function but for 200 in 500 threads it is a bit troublesome. If there's a 
way please tell me.

Or fetch it once per day?

Thanks!

I have data from production which are changing every day so i have to take 
it from database. 
I'll write it into Jmeter source code. If you would like to check it when 
i'll finish, tell me and i'll send it to you.

I think 2.0.3 includes a way to create screen dumps (^G IIRC) - if
not, then certainly 2.1 (only available in nightlies at present) does.
These can then be printed.

Create a testplan without any listeners. 
Set output format to CSV. 
Run as non-GUI with -l to create log file:

jmeter -n -t test.jmx -l test.jtl

This will make the most efficient use of memory.

We frequently run tests like that over a weekend, perhaps with
millions of transactions in total.

Probably could do so using BeanShell and JDBC, but there is currently
no built-in method of doing so.

You could create a file (from the database if necessary), and read it
with the StringFromFile or CSVRead functions (or CSVData if using a
2.1 nightly)

This would be more efficient than reading from the database,
particularly if you want to run a test more than once.

I think 2.0.3 includes a way to create screen dumps (^G IIRC) - if
not, then certainly 2.1 (only available in nightlies at present) does.

Create a testplan without any listeners. 
Set output format to CSV. 
Run as non-GUI with -l to create log file:

jmeter -n -t test.jmx -l test.jtl

This will make the most efficient use of memory.

there's a save graph feature in the nighthly which sebb mentioned. the
feature allows you to save most jmeter components to a file, including
samplers.  the current file format is PNG
