This module requires <a href="http://www.librelp.com">librelp</a> to be +present on the system. From the user's point of view, imrelp works much +like imtcp or imgssapi, except that no message loss can occur. Please +note that with the currently supported relp protocol version, a minor +message duplication may occur if a network connection between the relp +client and relp server breaks after the client could successfully send +some messages but the server could not acknowledge them. The window of +opportunity is very slim, but in theory this is possible. Future +versions of RELP will prevent this. Please also note that rsyslogd may +lose a few messages if rsyslog is shutdown while a network conneciton +to the server is broken and could not yet be recovered. Future version +of RELP support in rsyslog will prevent that. Please note that both +scenarios also exists with plain tcp syslog. RELP, even with the small +nits outlined above, is a much more reliable solution than plain tcp +syslog and so it is highly suggested to use RELP instead of plain tcp. +Clients send messages to the RELP server via omrelp.</p> +<p><b>Configuration Directives</b>:</p> +<ul> +<li>InputRELPServerRun <port><br> +Starts a RELP server on selected port</li> +</ul> +<b>Caveats/Known Bugs:</b> +<ul> +<li>see description</li> +</ul> +<p><b>Sample:</b></p> +<p>This sets up a RELP server on port 2514.<br> +</p> +<textarea rows="15" cols="60">$ModLoad imrelp # needs to be done just once +$InputRELPServerRun 2514 +</textarea> +<p>[<a href="rsyslog_conf.html">rsyslog.conf overview</a>] +[<a href="manual.html">manual index</a>] [<a href="http://www.rsyslog.com/">rsyslog site</a>]</p> +<p><font size="2">This documentation is part of the +<a href="http://www.rsyslog.com/">rsyslog</a> +project.<br> +Copyright © 2008 by <a href="http://www.gerhards.net/rainer">Rainer +Gerhards</a> and +<a href="http://www.adiscon.com/">Adiscon</a>. +Released under the GNU GPL version 3 or higher.</font></p> +</body></html>
