[Dnsmasq-discuss] send logs to a remote server

[John Pearson]

I'd like to send the logs to a remote server to process. I'm currently
leaning towards using rsyslog for that.

I looked into --log-facility sending to remote server but doesn't seem to
be supported.

Is there a better way than rsyslog? Maybe something built into dnsmasq that
I am missing?

Thanks!

Just a paranoid drift, because I've been bitten by it a few times in the
past - make certain that if you do go the rsyslog path, you ensure it is
setup to never block the local logging client(s) no matter what happens
with the remote logging destination. Otherwise, when something goes
awry with the remote logging destination the backpressure will affect
the logging clients (eg dnsmasq in this case though the times I've been
bitten were with other things).

This bit me long ago, and the result was the --log-async option, which
makes dnsmasq immune to backpressure from the logging system, and,
more importantly, avoids deadlocks when the log daemon makes DNS
queries through the local dnsmasq instance.


Cheers,

Simon.

Thanks. I'm going to go ahead and use rsyslog and also look into --log-async
option.
