A standard +text file is a file consisting of printable characters with lines +being delimited by LF.</p><p>The +file is read line-by-line and any line read is passed to rsyslog's rule +engine. The rule engine applies filter conditons and selects which +actions needs to be carried out.</p><p>As new lines are written they +are taken from the file and processed. Please note that this happens +based on a polling interval and not immediately. The file monitor +support file rotation. To fully work, rsyslogd must run while the file +is rotated. Then, any remaining lines from the old file are read and +processed and when done with that, the new file is being processed from +the beginning. If rsyslogd is stopped during rotation, the new file is +read, but any not-yet-reported lines from the previous file can no +longer be obtained.</p><p>When rsyslogd is stopped while monitoring a +text file, it records the last processed location and continues to work +from there upon restart. So no data is lost during a restart (except, +as noted above, if the file is rotated just in this very moment).</p><p>Currently, +the file must have a fixed name and location (directory). It is planned +to add support for dynamically generating file names in the future.</p><p>Multiple files may be monitored by specifying $InputRunFileMonitor multiple times. +</p> +<p><b>Configuration Directives</b>:</p> +<ul> +<li><strong>$InputFileName /path/to/file</strong><br> +The file being monitored.

If you would +like to see the colon after the tag, you need to specify it here (as +shown above).</li><li><span style="font-weight: bold;">$InputFileStateFile <name-of-state-file></span><br>Rsyslog +must keep track of which parts of the to be monitored file it already +processed. This is done in the state file. This file always is created +in the rsyslog working directory (configurable via $WorkDirectory). Be +careful to use unique names for different files being monitored. If +there are duplicates, all sorts of "interesting" things may happen. +Rsyslog currently does not check if a name is specified multiple times.</li><li><span style="font-weight: bold;">$InputRunFileMonitor</span><br>This <span style="font-weight: bold;">activates</span> the current monitor.
