All Implemented Interfaces:

Configurable, Reconfigurable<HTTPOperationLoggerConfig>

@Extensible

@DirectoryProxyServerExtension(appliesToLocalContent=true,

public abstract class ScriptedHTTPOperationLogger
extends java.lang.Object
implements Reconfigurable<HTTPOperationLoggerConfig>

This class defines an API that must be implemented by extensions which record information about interaction with HTTP clients. Scripted HTTP operation loggers may write information to files, but they may also write to other locations, including databases, message, queues, e-mail messages, or other targets.

Configuring Scripted HTTP Operation Loggers

In order to configure a scripted HTTP operation logger created using this API, use a command like:

      dsconfig create-log-publisher \
           --publisher-name "{logger-name}" \
           --type groovy-scripted-http-operation \
           --set enabled:true \
           --set "script-class:{class-name}" \
           --set "script-argument:{name=value}"
 

where "{logger-name}" is the name to use for the scripted HTTP operation logger instance, "{script-class}" is the fully-qualified name of the Groovy class written using this API, and "{name=value}" represents name-value pairs for any arguments to provide to the logger. If multiple arguments should be provided to the logger, then the "--set script-argument:{name=value}" option should be provided multiple times.

Constructor Detail

ScriptedHTTPOperationLogger

public ScriptedHTTPOperationLogger()

Creates a new instance of this scripted HTTP operation logger. All scripted HTTP operation logger implementations must include a default constructor, but any initialization should generally be done in the initializeHTTPOperationLogger method.

Method Detail

defineConfigArguments

public void defineConfigArguments(com.unboundid.util.args.ArgumentParser parser)
                           throws com.unboundid.util.args.ArgumentException

Updates the provided argument parser to define any configuration arguments which may be used by this extension. The argument parser may also be updated to define relationships between arguments (e.g., to specify required, exclusive, or dependent argument sets).

Specified by:

defineConfigArguments in interface Configurable

Parameters:

parser - The argument parser to be updated with the configuration arguments which may be used by this extension.

Throws:

com.unboundid.util.args.ArgumentException - If a problem is encountered while updating the provided argument parser.

initializeHTTPOperationLogger

public void initializeHTTPOperationLogger(HTTPServerContext serverContext,
                                          HTTPOperationLoggerConfig config,
                                          com.unboundid.util.args.ArgumentParser parser)
                                   throws com.unboundid.ldap.sdk.LDAPException

Initializes this scripted HTTP operation logger.

Parameters:

serverContext - A handle to the server context for the server in which this extension is running.

config - The general configuration for this HTTP operation logger.

parser - The argument parser which has been initialized from the configuration for this HTTP operation logger.

Throws:

com.unboundid.ldap.sdk.LDAPException - If a problem occurs while initializing this HTTP operation logger.

isConfigurationAcceptable

public boolean isConfigurationAcceptable(HTTPOperationLoggerConfig config,
                                         com.unboundid.util.args.ArgumentParser parser,
                                         java.util.List<java.lang.String> unacceptableReasons)

Indicates whether the configuration represented by the provided argument parser is acceptable for use by this extension. The parser will have been used to parse any configuration available for this extension, and any automatic validation will have been performed. This method may be used to perform any more complex validation which cannot be performed automatically by the argument parser.

Specified by:

isConfigurationAcceptable in interface Reconfigurable<HTTPOperationLoggerConfig>

Parameters:

config - The general configuration for this extension.

parser - The argument parser that has been used to parse the proposed configuration for this extension.

unacceptableReasons - A list to which messages may be added to provide additional information about why the provided configuration is not acceptable.

Returns:

true if the configuration in the provided argument parser appears to be acceptable, or false if not.

applyConfiguration

public com.unboundid.ldap.sdk.ResultCode applyConfiguration(HTTPOperationLoggerConfig config,
                                                            com.unboundid.util.args.ArgumentParser parser,
                                                            java.util.List<java.lang.String> adminActionsRequired,

Attempts to apply the configuration from the provided argument parser to this extension.

Specified by:

applyConfiguration in interface Reconfigurable<HTTPOperationLoggerConfig>

Parameters:

parser - The argument parser that has been used to parse the new configuration for this extension.

adminActionsRequired - A list to which messages may be added to provide additional information about any additional administrative actions that may be required to apply some of the configuration changes.

messages - A list to which messages may be added to provide additional information about the processing performed by this method.

Returns:

A result code providing information about the result of applying the configuration change. A result of SUCCESS should be used to indicate that all processing completed successfully. Any other result will indicate that a problem occurred during processing.

finalizeHTTPOperationLogger

public void finalizeHTTPOperationLogger()
