NAME
rb - The Report Browser Tool
DESCRIPTION
The Report Browser (RB) tool makes it possible to browse and format error reports written by the error
logger handler log_mf_h.
EXPORTS
filter(Filters)
filter(Filters, Dates)
Types:
Filters = [filter()]
filter() = {Key, Value} | {Key, Value, no} | {Key, RegExp, re} | {Key, RegExp, re, no}
Key = term()
Value = term()
RegExp = string() | {string, Options} | mp(), {mp(), Options}
Dates = {DateFrom, DateTo} | {DateFrom, from} | {DateTo, to}
DateFrom = DateTo = {date(), time()}
date() and time() are the same type as in the calendar module
This function displays the reports that match the provided filters.
When a filter includes the no atom it will exclude the reports that match that filter.
The reports are matched using the proplists module. The report must be a proplist to be matched
against any of the filters().
If the filter is of the form {Key, RegExp, re} the report must contain an element with key = Key
and Value must match the RegExp regular expression.
If the Dates parameter is provided, then the reports are filtered according to the date when they
occurred. If Dates is of the form {DateFrom, from} then reports that occurred after DateFrom are
displayed.
If Dates is of the form {DateTo, to} then reports that occurred before DateTo are displayed.
If two Dates are provided, then reports that occurred between those dates are returned.
If you only want to filter only by dates, then you can provide the empty list as the Filters
parameter.
See rb:grep/1 for more information on the RegExp parameter.
grep(RegExp)
Types:
RegExp = string() | {string, Options} | mp(), {mp(), Options}
All reports containing the regular expression RegExp are printed.
RegExp can be a string containing the regular expression; a tuple with the string and the options
for compilation; a compiled regular expression; a compiled regular expression and the options for
running it. Refer to the module re and specially the function re:run/3 for a definition of valid
regular expressions and options.
h()
help()
Prints the on-line help information.
list()
list(Type)
Types:
Type = type()
type() = error | error_report | info_msg | info_report | warning_msg | warning_report |
crash_report | supervisor_report | 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.
log_list()
log_list(Type)
Types:
Type = type()
type() = error | error_report | info_msg | info_report | warning_msg | warning_report |
crash_report | supervisor_report | progress
Same as list/0 or list/1 functions but result is printed to logfile, if set, otherwise to
standard_io.
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() | atom() | pid()
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, registered name or io_device. All reports will be
printed to the named file. The default is standard_io. The option {start_log, standard_error} is
not allowed and will be replaced by default 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() | atom() | pid()
Redirects all report output from the RB tool to the specified file, registered name or io_device.
stop()
Stops the rb_server.
stop_log()
Closes the log file. The output from the RB tool will be directed to standard_io.
