NAME

       snmpa_error_logger - Functions for Reporting SNMP Errors through the error_logger

DESCRIPTION

       The module snmpa_error_logger implements the snmpa_error_report behaviour (see snmpa_error_report ) containing two callback functions which
       are called in order to report SNMP errors.

       This module provides a simple mechanism for reporting SNMP errors. Errors are sent to the error_logger after a  size  check.  Messages  are
       truncated after 1024 chars. It is provided as an example.

       This module is the default error report module, but can be explicitly configured, see snmpa_error and configuration parameters .

EXPORTS

       config_err(Format, Args) -> void()

	      Types  Format = string()
		     Args = list()

	      The  function is called if an error occurs during the configuration phase, for example if a syntax error is found in a configuration
	      file.

	      Format and Args are as in io:format(Format, Args) .

       user_err(Format, Args) -> void()

	      Types  Format = string()
		     Args = list()

	      The function is called if a user related error occurs at run-time, for example if a user defined	instrumentation  function  returns
	      erroneous.

	      Format and Args are as in io:format(Format, Args) .

NAME

       log_mf_h - An Event Handler which Logs Events to Disk

DESCRIPTION

       The  log_mf_h is a gen_event handler module which can be installed in any gen_event process. It logs onto disk all events which are sent to
       an event manager. Each event is written as a binary which makes the logging very fast. However, a tool such as the Report Browser  (  rb  )
       must  be used in order to read the files. The events are written to multiple files. When all files have been used, the first one is re-used
       and overwritten. The directory location, the number of files, and the size of each file are configurable. The directory	will  include  one
       file called index , and report files 1, 2, .... .

EXPORTS

       init(Dir, MaxBytes, MaxFiles)
       init(Dir, MaxBytes, MaxFiles, Pred) -> Args

	      Types  Dir = string()
		     MaxBytes = integer()
		     MaxFiles = 0 < integer() < 256
		     Pred = fun(Event) -> boolean()
		     Event = term()
		     Args = args()

	      Initiates  the  event  handler.  This  function  returns	Args  ,  which should be used in a call to gen_event:add_handler(EventMgr,
	      log_mf_h, Args) .

	      Dir specifies which directory to use for the log files. MaxBytes specifies the size of each individual file. MaxFiles specifies  how
	      many  files  are used. Pred is a predicate function used to filter the events. If no predicate function is specified, all events are
	      logged.
