LoggingΒΆ

The package provides runtime information through the use of logging. To enable basic logs provided by sentinelhub enable logging on the DEBUG level.

import logging

logging.basicConfig(level=logging.DEBUG)

One can also redirect all warnings that occur during evaluation to the logger.

import logging

logging.basicConfig(level=logging.DEBUG)
logging.captureWarnings(True)

The sentinelhub package is using requests package for HTTP communication. In case standard logs are not detailed enough, it is possible to obtain full information about HTTP requests by propagating low-level urllib3 logs.

import logging
from http.client import HTTPConnection

HTTPConnection.debuglevel = 1

logging.basicConfig(level=logging.DEBUG)
requests_log = logging.getLogger("requests.packages.urllib3")
requests_log.setLevel(logging.DEBUG)
requests_log.propagate = True

Downloading is multi-threaded with the use of the standard threading library. The simplest way to keep track, which log comes from which thread, is to add thread names into logging formatting.

import logging

# The default format is '%(levelname)s:%(name)s:%(message)s'

logging.basicConfig(
    level=logging.DEBUG,
    format='%(levelname)s:%(name)s:%(threadName)s:%(message)s',
)

For more information on advanced logging configuration consult the official logging documentation, which also contains an advanced logging tutorial.
