Agent log limitation to 1MB - is it still valid?

[kpiwko]

Hi All,

in my tests I'm logging invalid requests to the log, which can easily exceed 1MB limit mentioned here http://www.cubrid.org/wiki_ngrinder/entry/how-to-adjust-logger-level during few hours (I haven't reached this limit yet, but I'm pretty close with 900kB per thread). Before creating an issue to make it configurable, I was looking into ngrinder (and grinder) code, but I was not able to find the place where is this limitation enforced.

The only thing I've found was a rolling logger setup for agent.log file.

Isn't that documentation some leftover from previous version? If not, where is this enforced?

Thanks,

Karel

This limitation comes from logback-worker.xml  file in grinder-3.9.1-patch.jar file in the agent)

You can open it there and modify the xml and repackage it.

However.. it's not the generally recommended approach.

In the large ngrinder deployment.. in which ngrinder is used with more than 1000 people(like we do), we can not expect what will happen in ngrinder.

We found some guys generate more than 10G log files per one test.. They didn't know what they're doing.

At that time, their scripts went wrong.. and each agent emits huge size of exception stacktrace logs..

Then.. these files was transferred to the controller from agents.. which means.. disaster to ngrinder controller and network as well.

The policies which nGrinder contains has been elaborated in our company very long time.

Awesome, that's exactly what I need. Thanks JunHo!

Just a note, I do not expect to generate such huge logs, it's rather about possibility to override it in cases when it becomes necessary.

I'm just telling you why I have to limit log size. :-)
