SysLog Understanding

[Symadept]

Hi,

I am using ASL to print the syslog. But here are the following points I am looking for.

1. Everytime I tried polling for next messages it always gives me the all the messages from the start. There is a timestamp entry. Is there a way I can able to print from the last time stamp?
2. How can I know that browser has be opened and closed from the SysLog messages?
3. How can I increase the log level, it seems to be always 4?
4. Can I know similar thing for other apps too like Camera etc.
5. Also can I understand what activities might have been happened within those apps.

Appreciate your help.

Regards
