Log centralization, display, transport and aggregation at scale v2
- by Eric DANNIELOU
This is a duplicate question of Log transport and aggregation at scale and http://stackoverflow.com/questions/1737693/whats-the-best-practice-for-centralised-logging, but the answers might differ now :
The softwares described in 2009 may have changed since (for example Octopussy evolved from version 0.9 to 1.0.5).
Rsyslog has become the default on most linux distro.
Requirements have changed (security, software configuration management, ...).
I'd like to ask the following questions :
How do you centralize, display and archive system logs?
How would you like to do it now if you had to?
Most linux distro use rsyslog nowadays, which can provide reliable log transport. But some older unices, network devices and maybe windows box still use old udp rfc-style transport. How did you manage to get reliable transport?
Storing logs for a few months can represent a huge amount of disk space. How do you store them? rdbms? Compressed and encrypted text files?
