Command for Asterisk log file please?


I run Asterisk

I cant get the log file for the day etc.

I have tried /var/log/asterisk/, it tells me “/var/log/asterisk/: cannot execute”

1)what am I doing wrong?
2)where can I get the complete call log for the day etc?

I need to have a look at what happens to calls at a certain time?

thank you in advance.
