[Bro] log streams in a bro cluster

Hi all,

I need some help with the logs generated by a Bro Cluster:

I have 5 bro scripts that run in all workers of my cluster 
infrastructure. All of them work OK, sending notices to the manager and 
all the staff, but one of them should create a LOG stream (warnings.log) 
that I can't find anywhere:

Log::create_stream(umas::WARN, [$columns=warn_info,$path="warnings"]);

If I run my script in a single bro installation, all logs and notices 
seem to work, but I need it working in a cluster infrastructure.

I expected this Log stream to be sent to the 'logs' directory in the 
manager, but that log file is not there. Only standard log files 
(dns.log, http.log, stdout.log, etc) are copied to the 'logs' directory.

This warnings.log file do not appear either anywhere in the worker, and 
not error log file is shown, so... I'm lost.

I anyone can shed some light into this, I would appreciate it.

The other problem I have is the following: My script should open a 
config file. In a single machine infrastructure this config file is in 
the same directory of the scripts, and everything work fine. The file is 
opened and read. However in a cluster infrastructure the file is not 
opened in the workers. I find that the file is copied by broctl to the 
worker BUT it is not read when the bro script is running. Anyone can 
tell me what I'm doing wrong or where should I locate that file in the 

Thank you for any help!!
