rb: The Report Browser Tool


rb - The Report Browser Tool


The Report Browser (RB) tool makes it possible to browse and format error reports written by the error logger handler log_mf_h.
grep(RegExp) Types RegExp = string() All reports containing the regular expression RegExp are printed. RegExp is a string containing the regular expression. Refer to the module regexp in the STDLIB reference manual for a definition of valid regular expressions. They are essentially the same as the UNIX command egrep. h() help() Prints the on-line help information. list() list(Type) Types Type = type() type() = crash_report | supervisor_report | error | progress This function lists all reports loaded in the rb_server. Each report is given a unique number that can be used as a reference to the report in the show/1 function. If no Type is given, all reports are listed. rescan() rescan(Options) Types Options = [opt()] Rescans the report directory. Options is the same as for start(). show() show(Report) Types Report = int() | type() If a type argument is given, all loaded reports of this type are printed. If an integer argument is given, the report with this reference number is printed. If no argument is given, all reports are shown. start() start(Options) Types Options = [opt()] opt() = {start_log, FileName} | {max, MaxNoOfReports} | {report_dir, DirString} | {type, ReportType} | {abort_on_error, Bool} FileName = string() | standard_io MaxNoOfReports = int() | all DirString = string() ReportType = type() | [type()] | all Bool = true | false The function start/1 starts the rb_server with the specified options, while start/0 starts with default options. The rb_server must be started before reports can be browsed. When the rb_server is started, the files in the specified directory are scanned. The other functions assume that the server has started. {start_log, FileName} starts logging to file. All reports will be printed to the named file. The default is standard_io. {max, MaxNoOfReports}. Controls how many reports the rb_server should read on start-up. This option is useful as the directory may contain 20.000 reports. If this option is given, the MaxNoOfReports latest reports will be read. The default is 'all'. {report_dir, DirString}. Defines the directory where the error log files are located. The default is {sasl, error_logger_mf_dir}. {type, ReportType}. Controls what kind of reports the rb_server should read on start-up. ReportType is a supported type, 'all', or a list of supported types. The default is 'all'. {abort_on_error, Bool}. This option specifies whether or not logging should be aborted if rb encounters an unprintable report. (You may get a report on incorrect form if the error_logger function error_msg or info_msg has been called with an invalid format string). If Bool is true, rb will stop logging (and print an error message to stdout) if it encounters a badly formatted report. If logging to file is enabled, an error message will be appended to the log file as well. If Bool is false (which is the default value), rb will print an error message to stdout for every bad report it encounters, but the logging process is never aborted. All printable reports will be written. If logging to file is enabled, rb prints * UNPRINTABLE REPORT * in the log file at the location of an unprintable report. start_log(FileName) Types FileName = string() Redirects all report output from the RB tool to the specified file. stop() Stops the rb_server. stop_log() Closes the log file. The output from the RB tool will be directed to standard_io. RB(3)
