[syslog-ng] Queueing of messages if remote loghost is down

[Eric Brown]

I'd like to centralize logs from 2-data centers to my corporate  
offices via tcp destinations at my data centers and a tcp source at  
my corporate office.

What if my data centers suffer network connectivity problems or I  
loose power at my corporate office? How long will syslog-ng keep  
queueing messages before I start loosing data? Will its attempts to  
retry connecting to my corporate office adversely affect overall  
system performance of the machine it is running on? Will it recover  
on its own after a few hours of lost connectivity?

Thanks,
Eric
