Is there a way to control/filter log message type (debug, info, warn, error) in a backtest?
If not, what is the purpose of having different type of log messages?
thanks
log control question
Hi Quantopian, could you give me a feedback on this question?
Maybe I wasn't clear enough. In my algorithms I use the different log type (debug, info, warn, error) to report different type of information but I don't want to have all those messages all the time in the backtest logs. For example I want to enable debug messages only when I see a bug and I like to dig in to details, but usually I am interested only in warning and error messages.
Is that possible to select which messages to display via code or via user interface?
Thank you
Hi Luca,
We haven't developed a log filtering feature. It's certainly something that would be useful, but we haven't gotten to it. One of the reasons that it hasn't happened was the debugger - that debugger is more powerful than logs or log filtering. We invested more time and love in the debugger than in logging.
Has the debugger worked for you?
Dan

Thank you for the reply Dan. The debugger works great for code/logic problems, but I like to have my algo collecting information on trends and statistical data, so that I can see those information when I am investigating some particular scenario. It would be nice to have that information logged and available all the time but displayed only when needed.
Thanks.
