take a look at linux-ha
It's a framework to manage HA (including active/active load sharing,
quorums, etc)
it extends the traditional init.d startup scripts to also include a
'status' call to tell if the service is active or not. the framework calls
this service periodically and if the service fails, it does a failover.
With the correct configuration (and software), it can do sub-second
failover.

David and all,
are you aware of any high availability APIs that would enable rsyslog to do
some kind of automatic failover in a cluster environment? I have never
specifically programmed for that and wonder if there are any options.

Subject: Re: [rsyslog] High availability on rsyslog (cluster)
depending on how active your logging is, you could watch the logs and
say
that if you don't receive any logs for 1 min (or whatever time is
approprate), somthing is wrong.
you could also generate known UDP logs to yourself and alert if they
don't
show up.

Hi,
I have a small question, I would need to setup an rsyslog
receiver/forwarder, listening on udp port, since some clients, only
support this option. I would need this service to be highly
available(I don't want to have two machines and having duplicated
information), but since this udp, I can't be for sure if the service
is running fine. What I thought is to indirectly check it, by having
another port listening on tcp and checking the tcp service, if the
service is not running on tcp I would assume the whole system is down
and would failover to the other instance of the cluster, that's the
only way I could think of, do you currently have another way?
thank you very much,
Regards,
Christian
