When to use rsyslog to avoid message loss?
A logging system should be capable of avoiding message loss in situations where the server is not reachable. To do so, unsent data needs to be buffered at the client while the server is offline. Then, once the server is up again, this data is to be sent. This can easily be acomplished by rsyslog.
What does remote mean in the rsyslog ruleset?
That means, that it will be used by any listener if it is not specified otherwise. Further, this ruleset uses the default log paths vor various facilities and severities. The ruleset “remote” on the other hand takes care of the local logging and forwarding of all log messages that are received either via UDP or TCP.
