[syslog-ng] syslog-ng Message Deliver Acknowledgment and Action

[Balazs Scheidler]

It depends what failure modes you want to protect against.

There can be
* network connection breaks
* Syslog-ng daemon crashes (client, server)
* audit daemon crashes

Syslog-ng has most of the infrastructure to carry out (flow control), but
some pieces are missing. The PE team did work in this area, they created
RLTP for app. Level network acknowledgements that would protect against
network and syslogng crashes. Even in that case though the ack information
can only be propagated back to your audit app by speaking RLTP.

Maybe you would need a queueing stack like amqp or 0mq, those tend to
provide explicit acks, and there are brokerless solutions as well.
