<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The cheapest option is to change the complete environment to syslog-ng and tcp transport. Tcp works way better than udp and if you adjust the client
fifo a bit you have quite a bit messages cached in the memory. I have this setup running with 800 clients and all clients are of course logging to two servers.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hi,<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Currently, I've just one syslog-ng server which receives messages from hundreds of rsyslog instances. I'm sending logs via UDP so if syslog-ng machine dies, logs will be missed.<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">How can I make the system more redundant? I want to achieve something like if the current syslog-ng machine goes down, some other machine should be able to take it's role.<o:p></o:p></p>
