NAME

       Search::Elasticsearch::Role::Logger - Provides common functionality to Logger
       implementations

VERSION

       version 8.12

DESCRIPTION

       This role provides common functionality to Logger implementations, to enable the logging
       of events and the tracing of request-response conversations with Elasticsearch nodes.

       See Search::Elasticsearch::Logger::LogAny for the default implementation.

CONFIGURATION

   "log_to"
       Parameters passed to "log_to" are used by Search::Elasticsearch::Role::Logger
       implementations to setup the "log_handle()".  See Search::Elasticsearch::Logger::LogAny
       for details.

   "log_as"
       By default, events emitted by "debug()", "info()", "warning()", "error()" and "critical()"
       are logged to the "log_handle()" under the category "elasticsearch.event", which can be
       configured with "log_as".

   "trace_to"
       Parameters passed to "trace_to" are used by Search::Elasticsearch::Role::Logger
       implementations to setup the "trace_handle()". See Search::Elasticsearch::Logger::LogAny
       for details.

   "trace_as"
       By default, trace output emitted by "trace_request()", "trace_response()", "trace_error()"
       and "trace_comment()" are logged under the category "elasticsearch.trace", which can be
       configured with "trace_as".

   "deprecate_to"
       Parameters passed to "deprecate_to" are used by Search::Elasticsearch::Role::Logger
       implementations to setup the "deprecate_handle()".  See
       Search::Elasticsearch::Logger::LogAny for details.

   "deprecate_as"
       By default, events emitted by "deprecation()" are logged to the "deprecate_handle()" under
       the category "elasticsearch.deprecation", which can be configured with "deprecate_as".

METHODS

   log_handle()
       Returns an object which can handle the methods: debug(), debugf(), is_debug(), info(),
       infof(), is_info(), warning(), warningf(), is_warning(), error(), errorf(), is_error(),
       critical(), criticalf() and  is_critical().

   trace_handle()
       Returns an object which can handle the methods: trace(), tracef() and is_trace().

   deprecate_handle()
       Returns an object which can handle the warnf() method.

   trace_request()
           $logger->trace_request($cxn,\%request);

       Accepts a Cxn object and request parameters and logs them if tracing is enabled.

   trace_response()
           $logger->trace_response($cxn,$code,$response,$took);

       Logs a successful HTTP response, where $code is the HTTP status code, $response is the
       HTTP body and $took is the time the request took in seconds

   trace_error()
           $logger->trace_error($cxn,$error);

       Logs a failed HTTP response, where $error is an Search::Elasticsearch::Error object.

   trace_comment()
           $logger->trace_comment($comment);

       Used to insert debugging comments into trace output.

   deprecation()
           $logger->deprecation($warning,$request)

       Issues a deprecation warning to the deprecation logger.
