Hi Arma,

It might be a good idea to first go through the logfile and see if you have no big issues. If this is not the case you can change the configuration of your Odoo environment. There is a parameter called log_level, which depends what type of output should be logged to the Odoo logfile. Navigate to your configuration file, which is usually under /etc/your-odoo-server.config and edit the file. Add in the following line:

log_level = 'warning'

These are the different log_level options available:

• info

• debug_rpc

• warn

• test

• critical

• debug_sql

• error

• debug

• debug_rpc_answer

• notset
  

Usually it is good to use warning as those may contain important information about possible issues. If you only want very minimal output when there is a big issue you can set the log_level to error.
Now save the file and restart your Odoo with this configuration:

sudo service your-odoo restart -c /etc/your-odoo-server.config

Yenthe
