public abstract class ScriptedErrorLogger
extends java.lang.Object
implements Reconfigurable<ErrorLoggerConfig>

This class defines an API that must be implemented by scripted extensions which record information about warnings, errors, and events which occur in the server.

Each error logger may configured to indicate whether whether to include or exclude log messages based on their category and/or severity. This is handled automatically by the server, so individual error logger implementations no not need to attempt to perform that filtering on their own. However, they may perform additional processing if desired to further narrow the set of messages that should be logged.

Configuring Groovy-Scripted Error Loggers

In order to configure a scripted error logger based on this API and written in the Groovy scripting language, use a command like:

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

where "{logger-name}" is the name to use for the error logger instance, "{class-name}" 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

ScriptedErrorLogger

public ScriptedErrorLogger()

Creates a new instance of this error logger. All error logger implementations must include a default constructor, but any initialization should generally be done in the initializeErrorLogger 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.

initializeErrorLogger

public void initializeErrorLogger(ServerContext serverContext,
                                  ErrorLoggerConfig config,
                                  com.unboundid.util.args.ArgumentParser parser)
                           throws com.unboundid.ldap.sdk.LDAPException

Initializes this error logger.

Parameters:

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

config - The general configuration for this error logger.

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

Throws:

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

finalizeErrorLogger

public void finalizeErrorLogger()

Performs any cleanup which may be necessary when this error logger is to be taken out of service.

isConfigurationAcceptable

public boolean isConfigurationAcceptable(ErrorLoggerConfig 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<ErrorLoggerConfig>

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(ErrorLoggerConfig config,
                                                            com.unboundid.util.args.ArgumentParser parser,
                                                            java.util.List<java.lang.String> adminActionsRequired,
                                                            java.util.List<java.lang.String> messages)

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

Specified by:

applyConfiguration in interface Reconfigurable<ErrorLoggerConfig>

Parameters:

config - The general configuration for this extension.

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.

logError

public abstract void logError(LogCategory category,
                              LogSeverity severity,
                              long messageID,
                              java.lang.String message)

Records information about the provided message, if appropriate.

Parameters:
