Where can I find the whole system log and where can I find the output of LogObject->Dumper()

[OTRSRDNewbie]

I am not familiar yet with what is inside the $Param or which objects are supported on say a ACL or Generic Event or a Custom Module.

I was hoping to do a dumper, then I discovered there is a LogObject->Dumper(). I tried this but I can't seems to see this in the System Log or anywhere.

LogObject->Log( Priority => 'notice', Message => 'Hello World') can be seen in the system log. Where is the output of LogObject->Dumper() go?

For example I am not sure if I created a Custom Module, executed it in a Generic Agent. Then I want to know what are the parameters availble and objects available.
