SW_DebugLog

Logging Options

If something doesn't work as expected, there are a few options that can help identify the problem.

Relevant Parameters

Module	Parameter	Default	Type or range	Comment
(Global)	debug	3	1 .... 5	Debug level (will be deprecated soon)
(Global)	errorlog_path	error_log	string	Directory path for Error log
(Global)	errorlog_level	"INFO"	"NOTSET", "DEBUG", "INFO", "WARN", "ERROR", "CRITICAL"	verbosity of error log (see python manual)
Log	filename	"log.txt"	string	path to transcript file
Screen	show_ctrl	true	false / true	if true, show control sequences on screen
Screen	show_info	false	false / true	if true, show additional info on screen
Screen	show_BuZi	false	false / true	if true, show special characters for Bu / Zi on screen
ED1000SC	recv_debug	false	false / true	If true, output recv_debug.log file inside which the respective filter power output levels for every sample are recorded. Use only for debugging (file will grow quickly).

Error logging

All logged information is saved in a monthly rotating file inside the path given. If the latter is relative, it's interpreted relative to where this Python file is stored. The parameter errorlog_path specifies the directory where piTelex will put its logging output.

The logging level can be set in telex.json. Available loglevels are NOTSET, DEBUG, INFO, WARN, ERROR, CRITICAL. Only log messages that reach or exceed the configured level will produce an entry in the logfile. Standard log level is INFO.

Note: Use DEBUG level with care: Depending on the selected modules the error log can grow rapidly! Keep an eye on your logfile :-)

Module log:

The above mentioned error logging is different from the function of the log module. It implements a communication trace log (i.e. it logs the data read from all piTelex modules). To use this kind of logging, include and enable the module and specify the filename of the log file. filenamemay be an absolute file path: if given as a relative path, it is related to piTelex' home directory. This file logs all data and commands (ESC-*) that run through the central loop, in correct order.

Module screen:

If enabled, this module can be equipped with more verbosity by setting show_ctrl, show_BuZi and/or show_info to true.

Module ED1000:

To help identify problems with ED1000 devices, enabling recv_debug gives you a very verbose log file recv_debug.log of filter power output levels for every sample.

Miscellaneous

Furthermore, wireshark is a useful tool for debugging at network level. piTelex' subdirectory tsharkcontains some suitable cli scripts; the output can be visualized by wireshark's GUI.

Good luck!
