Again. I am not doing anything with these messages. Yes messages are not
API. I do not need them for a live and running system, at all.

I need it for a dead system. for a long dead system. A system that has failed
3 days ago and all I have is the system/application logs and the Kernel logs.

I guess I'm antic and you guys have other means for these things, I wish to
learn then. So far all we are asking to keep are the logs, Is there something
else I need to store from a *past* running system?

Until now this gave me a very good place to start my investigation. With
empty log files, how do I then proceed?

It looks like everyone agrees with you though. I wish I knew something you
guys know, I do not see how I can analyze failing systems without logs.

[I promise this is my last email on the subject]

Thanks
