Logging

openBURST uses config files to configure logging.

see .json logger config files in db/
for intro to python logging see: Python Logging
e.g. to configure logging of dem Server change “burst_dem_logging.json” file.
e.g. to change logging level from CRITICAL to DEBUG, just change to “DEBUG” in the line:

"root": {
        "level": "DEBUG",
        "handlers": ["file_handler"]
    }

and in

"file_handler": {
            "class": "logging.handlers.RotatingFileHandler",
            "level": "DEBUG",
            "formatter": "simple",
            "filename": "/tmp/burst_dem.log",
            "maxBytes": 10485760,
            "backupCount": 20,
            "encoding": "utf8"
        }

if you add “console” to the line of handlers, all the logging level output will also be shown on the console.
the above json file is configured that the logging messages goes to the file /tmp/burst_dem.log
OPEBURST uses “multitail” to keep reading the logging file
