Class AbstractNCSARequestLog

java.lang.Object

org.eclipse.jetty.util.component.AbstractLifeCycle

org.eclipse.jetty.server.AbstractNCSARequestLog

All Implemented Interfaces:

RequestLog, LifeCycle

Direct Known Subclasses:

NCSARequestLog, Slf4jRequestLog

public abstract class AbstractNCSARequestLog
extends AbstractLifeCycle
implements RequestLog

Base implementation of the RequestLog outputs logs in the pseudo-standard NCSA common log format. Configuration options allow a choice between the standard Common Log Format (as used in the 3 log format) and the Combined Log Format (single log format). This log format can be output by most web servers, and almost all web log analysis software can understand these formats.

AbstractNCSARequestLog

public AbstractNCSARequestLog()

Method Detail

isEnabled

protected abstract boolean isEnabled()

Is logging enabled

Returns:

true if logging is enabled

write

public abstract void write(String requestEntry)
                    throws IOException

Write requestEntry out. (to disk or slf4j log)

Parameters:

requestEntry - the request entry

Throws:

IOException - if unable to write the entry

log

public void log(Request request,
                Response response)

Writes the request and response information to the output stream.

Specified by:

log in interface RequestLog

Parameters:

request - The request to log.

response - The response to log. Note that for some requests the response instance may not have been fully populated (Eg 400 bad request responses are sent without a servlet response object). Thus for basic log information it is best to consult Response.getCommittedMetaData() and Response.getHttpChannel() directly.

See Also:

RequestLog.log(Request, Response)

logExtended

protected void logExtended(StringBuilder b,
                           Request request,
                           Response response)
                    throws IOException

Writes extended request and response information to the output stream.

Parameters:

b - StringBuilder to write to

request - request object

response - response object

Throws:

IOException - if unable to log the extended information

setIgnorePaths

public void setIgnorePaths(String[] ignorePaths)

Set request paths that will not be logged.

Parameters:

ignorePaths - array of request paths

getIgnorePaths

public String[] getIgnorePaths()

Returns:

array of request paths

setLogCookies

public void setLogCookies(boolean logCookies)

Parameters:

logCookies - true - values of request cookies will be logged, false - values of request cookies will not be logged

getLogCookies

public boolean getLogCookies()

Retrieve log cookies flag

Returns:

value of the flag

setLogServer

public void setLogServer(boolean logServer)

Controls logging of the request hostname.

Parameters:

logServer - true - request hostname will be logged, false - request hostname will not be logged

getLogServer

public boolean getLogServer()
