public class SyslogHandler
extends ExtHandler

A syslog handler for logging to syslogd.

This handler can write to syslog servers that accept the RFC3164 and RFC5424 formats. Writes can be done via TCP, SSL over TCP or UDP protocols. You can also override the output stream if a custom protocol is needed.

```
public final void doPublish(ExtLogRecord record)
```
    Description copied from class: ExtHandler
    
    Do the actual work of publication; the record will have been filtered already. The default implementation does nothing except to flush if the autoFlush property is set to true; if this behavior is to be preserved in a subclass then this method should be called after the record is physically written.
    
    Overrides:
    
    doPublish in class ExtHandler
    
    Parameters:
    
    record - the log record to publish
  - close
```
public void close()
```
    Description copied from class: ExtHandler
    
    Close all child handlers.
    
    Specified by:
    
    close in interface Closeable

  - getAppName
```
public String getAppName()
```
    Gets app name used when formatting the message in RFC5424 format. By default the app name is "java".
    
    Returns:
    
    the app name being used
  - setAppName
```
public void setAppName(String appName)
```
    Sets app name used when formatting the message in RFC5424 format. By default the app name is "java". If set to null the ExtLogRecord.getProcessName() will be used.
    
    Parameters:
    
    appName - the app name to use
    
    Throws:
    
    SecurityException - if a security manager exists and if the caller does not have LoggingPermission(control) or the handler is protected
  - isBlockOnReconnect
```
public boolean isBlockOnReconnect()
```
    Indicates whether or not a TCP or SSL TCP connection should block when attempting to reconnect.
    
    Returns:
    
    true if blocking is enabled, otherwise false
  - setBlockOnReconnect
```
public void setBlockOnReconnect(boolean blockOnReconnect)
```
    Enables or disables blocking when attempting to reconnect a TCP or SSL TCP protocol.
    If set to true the publish methods will block when attempting to reconnect. This is only advisable to be set to true if using an asynchronous handler.
    
    Parameters:
    
    blockOnReconnect - true to block when reconnecting or false to reconnect asynchronously discarding any new messages coming in
  - isEscapeEnabled
```
@Deprecated
public boolean isEscapeEnabled()
```
    Deprecated. escaping message values is not required per RFC5424 and is no longer supported in this handler
    
    Checks whether or not characters below decimal 32, traditional US-ASCII control values expect DEL, are being escaped or not.
    
    Returns:
    
    false
  - setEscapeEnabled
```
@Deprecated
public void setEscapeEnabled(boolean escapeEnabled)

```
public boolean isUseCountingFraming()
```
    Returns true if the message size should be prefixed to the message being sent.
    See http://tools.ietf.org/html/rfc6587 for more details on framing types.
    
    Returns:
    
    the message transfer type
  - setUseCountingFraming
```
public void setUseCountingFraming(boolean useCountingFraming)
```
    Set to true if the message being sent should be prefixed with the size of the message.
    See http://tools.ietf.org/html/rfc6587 for more details on framing types.
    
    Parameters:
    
    useCountingFraming - true if the message being sent should be prefixed with the size of the message
    
    Throws:
    
    SecurityException - if a security manager exists and if the caller does not have LoggingPermission(control) or the handler is protected

public SyslogHandler.SyslogType getSyslogType()
```
    Returns the syslog type this handler is using to format the message sent.
    
    Returns:
    
    the syslog type
  - setSyslogType
```
public void setSyslogType(SyslogHandler.SyslogType syslogType)
```
    Set the syslog type this handler should use to format the message sent.
    
    Parameters:
    
    syslogType - the syslog type
    
    Throws:
    
    SecurityException - if a security manager exists and if the caller does not have LoggingPermission(control) or the handler is protected
  - getProtocol
```
public SyslogHandler.Protocol getProtocol()
```
    The protocol used to connect to the syslog server
    
    Returns:
    
    the protocol
  - setProtocol
```
public void setProtocol(SyslogHandler.Protocol type)
```
    Sets the protocol used to connect to the syslog server
    
    Parameters:
    
    type - the protocol
  - setOutputStream
```
public void setOutputStream(OutputStream out)
```
    Sets the output stream for the syslog handler to write to.
    Setting the output stream closes any already established connections or open output streams and will not open any new connections until the output stream is set to null. The protocol, #setServerAddress(java.net.InetAddress), server address, server hostname or port have no effect when the output stream is set.
    
    Parameters:
    
    out - the output stream to write to
  - isTruncate
```
public boolean isTruncate()
```
    Checks if the message should truncated if the total length exceeds the maximum length.
    
    Returns:
    
    true if the message should be truncated if too large, otherwise false
  - setTruncate
```
public void setTruncate(boolean truncate)
```
    Set to true if the message should be truncated if the total length the maximum length.
    Set to false if the message should be split and sent as multiple messages. The header will remain the same for each message sent. The wrapping is not a word based wrap and could split words between log messages.
    
    Parameters:
    
    truncate - true to truncate, otherwise false to send multiple messages
  - calculatePriority
```
protected int calculatePriority(Level level,
                                SyslogHandler.Facility facility)
