Too many message in Experts log

 
I see many inicator load message in experts log, e.g.

13:12:50 MACD EURJPY,H4: loaded successfully
13:12:50 RSI EURJPY,H4: loaded successfully
...
13:12:50 MACD EURJPY,H4: initialized
13:12:50 RSI EURJPY,H4: initialized
...

"no message is good message",
Is it exists an option which to set the log level? I need it log the alert message, and fail message only.
 
Thank you for your suggestion. But we will not to modify it, sorry.
