In essence,<br> -this is the "file" part of selector lines (and this is why we are not -sure output channel syntax will stay after the next review). There is a<br> -difference, though: selector channels both have filter conditions -(currently facility and severity) as well as the output destination. -they can only be used to write to files - not pipes, ttys or whatever -Output channels define the output definition, only. As of this build, -else. If we stick with output channels, this will change over time.</p> -<p>In concept, an output channel includes everything needed to -know about an output actions. In practice, the current implementation -only carries<br> -a filename, a maximum file size and a command to be issued when this -file size is reached. More things might be present in future version, -which might also change the syntax of the directive.</p> -<p>Output channels are defined via an $outchannel directive. It's -syntax is as follows:<br> -<br> -$outchannel name,file-name,max-size,action-on-max-size<br> -<br> -name is the name of the output channel (not the file), file-name is the -file name to be written to, max-size the maximum allowed size and -action-on-max-size a command to be issued when the max size is reached. -This command always has exactly one parameter. The binary is that part -of action-on-max-size before the first space, its parameter is -everything behind that space.<br> -<br> -Please note that max-size is queried BEFORE writing the log message to -the file. So be sure to set this limit reasonably low so that any -message might fit. For the current release, setting it 1k lower than -you expected is helpful. The max-size must always be specified in bytes -- there are no special symbols (like 1k, 1m,...) at this point of -development.<br> -<br> -Keep in mind that $outchannel just defines a channel with "name". It -does not activate it. To do so, you must use a selector line (see -below). That selector line includes the channel name plus an $ sign in -front of it. A sample might be:<br> -<br> -*.* :omfile:$mychannel<br> -<br> -In its current form, output channels primarily provide the ability to -size-limit an output file. To do so, specify a maximum size. When this -size is reached, rsyslogd will execute the action-on-max-size command -and then reopen the file and retry. The command should be something -like a <a href="log_rotation_fix_size.html">log rotation -script</a> or a similar thing.</p> -<p>If there is no action-on-max-size command or the command did -not resolve the situation, the file is closed and never reopened by -rsyslogd (except, of course, by huping it). This logic was integrated -when we first experienced severe issues with files larger 2gb, which -could lead to rsyslogd dumping core. In such cases, it is more -appropriate to stop writing to a single file. Meanwhile, rsyslogd has -been fixed to support files larger 2gb, but obviously only on file -systems and operating system versions that do so. So it can still make -sense to enforce a 2gb file size limit.</p> - -<p>[<a href="manual.html">manual index</a>] -[<a href="rsyslog_conf.html">rsyslog.conf</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>.
