Ali,

Grinder Analyzer supports analyzing multiple log files at once, provided that they are all from the same test, and they are doing similar workloads. (In other words, in each log file, 'test 1' must refer to the same type of request/s). Just list each log file on the command line, and be sure to to put the data files in quotes. Here is the usage:

jython ./analyzer.py "<grinder data file(s)>" <grinder mapping file>

See http://track.sourceforge.net/usingAnalyzer.html for additional detail.

The concept of 'users' doesn't have much meaning in The Grinder. If you want to go down that road, you will need your own rules of thumb to approximate the number of actual users based on information Grinder and Grinder Analyzer does give you -- TPS or possibly on the total number of Grinder threads/processes.

Hello guys,

I am trying to test a proxy server with heavy load and my objective is clear: Increase the number of users to the proxy to find out at which point (i.e. approximate number of users) the proxy starts to run slower and drop responding.

I have setup the grinder and it connects successfully to the proxy server. To increase the number of users, I have manipulate the properties file to have:
- 5 processes, each with 50 threads
- Add one process every 15 seconds

The test runs and I have the results, but my problem is to analyze the result out.
I now have 5 log files and 5 data log files with all the statistics.

My plan was to compare the number of users which are increasing over time against the test time they took to complete. Then comparing the two on a graph basis may give me a estimation about what I'm looking for.

What I do not understand is where is the number of actual accesses to the target webpage through the proxy.
The Thread column apparently shows the thread number, not the number of threads/users.

I have tried using the GrinderAnalyzer tool, and can get results of one result file out. The problem with this are:
1. How to import multiple data files with multiple mapping files, didn't find much on the instruction page.
2. It is giving me the transaction load, is that the same as the number of actual accesses to the target webpage?

I would appreciate your help to guide me how can I achieve my objective using Grinder if I'm doing it wrong, or how to analyze the results I have out.

Thank you very much.
