This directive works hand-in-hand with the multiple actions per selector feature. It can be used, for example, to create rules that automatically switch destination servers or databases to a (set of) backup(s), if the primary server fails. Note that this feature depends on proper implementation of the suspend feature in the output module. All built-in output modules properly support it (most importantly the database write and the syslog message forwarder).</p> +<p>This selector processes all messages it receives (*.*). It tries to forward every message to primary-syslog.example.com (via tcp). If it can not reach that server, it tries secondary-1-syslog.example.com, if that fails too, it tries secondary-2-syslog.example.com. If neither of these servers can be connected, the data is stored in /var/log/localbuffer. Please note that the secondaries and the local log buffer are only used if the one before them does not work. So ideally, /var/log/localbuffer will never receive a message. If one of the servers resumes operation, it automatically takes over processing again.</p> +<p>We strongly advise not to use repeated line reduction together with ActionExecOnlyIfPreviousIsSuspended. It may lead to "interesting" and undesired results (but you can try it if you like).</p> +<p><b>Sample:</b></p> +<p><code><b>*.* @@primary-syslog.example.com +<br>$ActionExecOnlyIfPreviousIsSuspended on +<br>& @@secondary-1-syslog.example.com # & is used to have more than one action for +<br>& @@secondary-2-syslog.example.com # the same selector - the mult-action feature +<br>& /var/log/localbuffer +<br>$ActionExecOnlyIfPreviousIsSuspended off # to re-set it for the next selector </b></code></p> + +<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 © 2007 by <a href="http://www.gerhards.net/rainer">Rainer Gerhards</a> and +<a href="http://www.adiscon.com/">Adiscon</a>.
