RsSmw Logger

Check the usage in the Getting Started chapter here.

class ScpiLogger

Base class for SCPI logging

mode

Sets the logging ON or OFF. Additionally, you can set the logging ON only for errors. Possible values:

• LoggingMode.Off - logging is switched OFF

• LoggingMode.On - logging is switched ON

• LoggingMode.Errors - logging is switched ON, but only for error entries

• LoggingMode.Default - sets the logging to default - the value you have set with logger.default_mode

stop() → None

Stops the logging. This is the same as: mode = LoggingMode.Off

start() → None

Starts the logging with the last defined LoggingMode. Default is LoggingMode.On

default_mode

Sets / returns the default logging mode. You can recall the default mode by calling the ‘logger.mode = LoggingMode.Default’.

device_name: str

Use this property to change the resource name in the log from the default Resource Name (e.g. TCPIP::192.168.2.101::INSTR) to another name e.g. ‘MySigGen1’.

set_logging_target(target, console_log: Optional[bool] = None, udp_log: Optional[bool] = None) → None

Sets logging target - the target must implement write() and flush(). You can optionally set the console and UDP logging ON or OFF. This method switches the logging target global OFF.

get_logging_target()

Based on the global_mode, it returns the logging target: either the local or the global one.

set_logging_target_global(console_log: Optional[bool] = None, udp_log: Optional[bool] = None) → None

Sets logging target to global. The global target must be defined. You can optionally set the console and UDP logging ON or OFF.

log_to_console

Returns logging to console status.

log_to_udp

Returns logging to UDP status.

log_to_console_and_udp

Returns true, if both logging to UDP and console in are True.

info_raw(log_entry: str, add_new_line: bool = True) → None

Method for logging the raw string without any formatting.

info(start_time: datetime.datetime, end_time: datetime.datetime, log_string_info: str, log_string: str, cmd: Optional[str] = None) → None

Method for logging one info entry. For binary log_string, use the info_bin()

error(start_time: datetime.datetime, end_time: datetime.datetime, log_string_info: str, log_string: str, cmd: Optional[str] = None) → None

Method for logging one error entry.

set_relative_timestamp(timestamp: datetime.datetime) → None

If set, the further timestamps will be relative to the entered time.

set_relative_timestamp_now() → None

Sets the relative timestamp to the current time.

get_relative_timestamp() → datetime.datetime

Based on the global_mode, it returns the relative timestamp: either the local or the global one.

clear_relative_timestamp() → None

Clears the reference time, and the further logging continues with absolute times.

flush() → None

Flush all the entries.

sync_from(source: RsSmw.Internal.ScpiLogger.ScpiLogger) → None

Synchronises this Logger with the source logger.

log_status_check_ok

Sets / returns the current status of status checking OK. If True (default), the log contains logging of the status checking ‘Status check: OK’. If False, the ‘Status check: OK’ is skipped - the log is more compact. Errors will still be logged.

clear_cached_entries() → None

Clears potential cached log entries. Cached log entries are generated when the Logging is ON, but no target has been defined yet.

set_format_string(value: str, line_divider: str = '\n') → None

Sets new format string and line divider. If you just want to set the line divider, set the format string value=None The original format string is: PAD_LEFT12(%START_TIME%) PAD_LEFT25(%DEVICE_NAME%) PAD_LEFT12(%DURATION%)  %LOG_STRING_INFO%: %LOG_STRING%

Additional variables to use: %SCPI_COMMAND%.

restore_format_string() → None

Restores the original format string and the line divider to LF

abbreviated_max_len_ascii: int

Defines the maximum length of one ASCII log entry. Default value is 200 characters.

abbreviated_max_len_bin: int

Defines the maximum length of one Binary log entry. Default value is 2048 bytes.

abbreviated_max_len_list: int

Defines the maximum length of one list entry. Default value is 100 elements.

bin_line_block_size: int

Defines number of bytes to display in one line. Default value is 16 bytes.

udp_port

Returns udp logging port.

target_auto_flushing

Returns status of the auto-flushing for the logging target.

log_info_replacer: RsSmw.Internal.ScpiLogger.LogInfoReplacer

Replacer for Log Info Strings.

class LogInfoReplacer

Replacer, that takes the SCPI Logger Log Info and customizes its value.

Create the new LogInfoReplacer either with empty replacer dictionaries, or the ones from another LogInfoReplacer.

set_full_replacer(repl_dict: Dict[str, str]) → None

Sets the full-replacer dictionary. This replacer searches the dictionary (case-sensitive) for the key that equals the LogInfoString, and replaces the whole info string with the string value associated with that key.

put_full_replacer_item(match: str, replace: str) → None

Sets/replaces one item in the full replacer.

pop_full_replacer_item(match: str) → None

Pops(removes) the entered full replacer item.

set_regex_sr_replacer(repl_dict: Dict[re.Pattern, str]) → None

Sets the regex search&replace replacer dictionary. The replacer uses the re.sub() method of each key and replaces the matched substring with the string value associated with that key.

put_regex_sr_replacer_item(search: re.Pattern, replace: str) → re.Pattern

Sets/replaces one item in the regex replacer. The key can be either a regex pattern, or a string. In case of the string, the key is compiled to a regex pattern, before it is put into the replacing dictionary. Returns the resulting search regex pattern.

pop_regex_sr_replacer_item(search: re.Pattern) → None

Pops(removes) the entered regex replacer item. The key can be either a regex pattern, or a string. In case of the string, the key is compiled to a regex pattern prior to popping.

clear_replacers()

Clears both full and regex replacer dictionaries.
