/**
|
|
* Log handler that supports sending log events to a syslog server using RFC
|
|
* 3164 formatted UDP packets.
|
|
*
|
|
* Monolog's SyslogUdpHandler creates a partial RFC 5424 header (PRI and
|
|
* VERSION) and relies on the associated formatter to complete the header and
|
|
* message payload. This makes using it with a fixed format formatter like
|
|
* \Monolog\Formatter\LogstashFormatter impossible. Additionally, the
|
|
* direct syslog input for Logstash only handles RFC 3164 syslog packets.
|
|
*
|
|
* This Handler should work with any Formatter. The formatted message will be
|
|
* prepended with an RFC 3164 message header and a partial message body. The
|
|
* resulting packet will looks something like:
|
|
*
|
|
* <PRI>DATETIME HOSTNAME PROGRAM: MESSAGE
|
|
*
|
|
* This format works as input to rsyslog and can also be processed by the
|
|
* default Logstash syslog input handler.
