extends <a href="../plugins/Receiver.html" title="class in org.apache.log4j.plugins">Receiver</a></pre>
<div class="block">LogFilePatternReceiver can parse and tail log files, converting entries into
LoggingEvents. If the file doesn't exist when the receiver is initialized, the
receiver will look for the file once every 10 seconds.
<p>
This receiver relies on java.util.regex features to perform the parsing of text in the
log file, however the only regular expression field explicitly supported is
a glob-style wildcard used to ignore fields in the log file if needed. All other
fields are parsed by using the supplied keywords.
<p>
<b>Features:</b><br>
- specify the URL of the log file to be processed<br>
- specify the timestamp format in the file (if one exists, using patterns from <a href="https://docs.oracle.com/javase/8/docs/api/java/text/SimpleDateFormat.html?is-external=true" title="class or interface in java.text" class="externalLink"><code>SimpleDateFormat</code></a>)<br>
- specify the pattern (logFormat) used in the log file using keywords, a wildcard character (*) and fixed text<br>
- 'tail' the file (allows the contents of the file to be continually read and new events processed)<br>
- supports the parsing of multi-line messages and exceptions
- 'hostname' property set to URL host (or 'file' if not available)
- 'application' property set to URL path (or value of fileURL if not available)
- 'group' property can be set to associate multiple log file receivers
<p>
<b>Keywords:</b><br>
TIMESTAMP<br>
LOGGER<br>
LEVEL<br>
THREAD<br>
CLASS<br>
FILE<br>
LINE<br>
METHOD<br>
RELATIVETIME<br>
MESSAGE<br>
NDC<br>
PROP(key)<br>
(NL)<br>
<p>
(NL) represents a new line embedded in the log format, supporting log formats whose fields span multiple lines
<p>
Use a * to ignore portions of the log format that should be ignored
<p>
Example:<br>
If your file's patternlayout is this:<br>
<b>%d %-5p [%t] %C{2} (%F:%L) - %m%n</b>
<p>
specify this as the log format:<br>
<b>TIMESTAMP LEVEL [THREAD] CLASS (FILE:LINE) - MESSAGE</b>
<p>
To define a PROPERTY field, use PROP(key)
<p>
Example:<br>
If you used the RELATIVETIME pattern layout character in the file,
you can use PROP(RELATIVETIME) in the logFormat definition to assign
the RELATIVETIME field as a property on the event.
<p>
If your file's patternlayout is this:<br>
<b>%r [%t] %-5p %c %x - %m%n</b>
<p>
specify this as the log format:<br>
<b>PROP(RELATIVETIME) [THREAD] LEVEL LOGGER * - MESSAGE</b>
<p>
Note the * - it can be used to ignore a single word or sequence of words in the log file
(in order for the wildcard to ignore a sequence of words, the text being ignored must be
followed by some delimiter, like '-' or '[') - ndc is being ignored in the following example.
<p>
Assign a filterExpression in order to only process events which match a filter.
If a filterExpression is not assigned, all events are processed.
<p>
<b>Limitations:</b><br>
- no support for the single-line version of throwable supported by patternlayout<br>
(this version of throwable will be included as the last line of the message)<br>
- the relativetime patternLayout character must be set as a property: PROP(RELATIVETIME)<br>
- messages should appear as the last field of the logFormat because the variability in message content<br>
- exceptions are converted if the exception stack trace (other than the first line of the exception)<br>
is stored in the log file with a tab followed by the word 'at' as the first characters in the line<br>
- tailing may fail if the file rolls over.
<p>
<b>Example receiver configuration settings</b> (add these as params, specifying a LogFilePatternReceiver 'plugin'):<br>
param: "timestampFormat" value="yyyy-MM-d HH:mm:ss,SSS"<br>
param: "logFormat" value="PROP(RELATIVETIME) [THREAD] LEVEL LOGGER * - MESSAGE"<br>
param: "fileURL" value="file:///c:/events.log"<br>
param: "tailing" value="true"
<p>
This configuration will be able to process these sample events:<br>
