@Extensible @DirectoryServerExtension @DirectoryProxyServerExtension(appliesToLocalContent=true, appliesToRemoteContent=false) @SynchronizationServerExtension(appliesToLocalContent=true, appliesToSynchronizedContent=false) @MetricsEngineExtension @IdentityBrokerExtension @ThreadSafety(level=INTERFACE_THREADSAFE) public abstract class ScriptedFileBasedErrorLogger
This class defines an API that may be used to create a specific type of
scripted error logger which is intended to write log messages to text files.
This is a convenience for developers which wish to create custom error
loggers that write to text files and provides support for a wide range of
functionality including high-performance and highly-concurrent logging. All
of the options available to ScriptedErrorLogger
implementations are
available for file-based error loggers, as well as options for indicating
the log file path, the rotation and retention policies, whether to buffer the
output, etc.
Note that scripted file-based error loggers will automatically be registered
within the server as disk space consumers, so there is no need to implement
the DiskSpaceConsumer
interface. Also note that configuration change related to the log file
(e.g., the log file path, buffer size, queue size, etc.) will also
automatically be handled by the server, so subclasses only need to be
concerned about changes to the custom arguments they define.
dsconfig create-log-publisher \ --publisher-name "{logger-name}" \ --type groovy-scripted-file-based-error \ --set enabled:true \ --set "log-file:{path}" \ --set "rotation-policy:{rotation-policy-name}" \ --set "retention-policy:{retention-policy-name}" \ --set "script-class:{class-name}" \ --set "script-argument:{name=value}"where "{logger-name}" is the name to use for the error logger instance, "{path}" is the path to the log file to be written, "{rotation-policy-name}" is the name of the log rotation policy to use for the log file, "{retention-policy-name}" is the name of the log retention policy to use for the log file, "{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. It is also possible to specify
multiple log rotation and/or retention policies if desired.
