PyLogging is a light-weight python logging library. It provides ability to write logs in your own customized format. It is also provides support for custom log filters, custom log actions and email notifications.
Current version: [v1.0.2]
To install PyLogging run this command:
pip install pylogging
or download Package then run this command:
pip install PyLogging-1.0.2.zip
After installing the library, Read the following usage criteria:
The typical usage of this library is like the following:
import pylogging
import os
# Logs Dir Absolute Path
logs_path = os.path.dirname(os.path.abspath(__file__)) + '/logs/'
# Create Logger Instance
logger = pylogging.PyLogging(LOG_FILE_PATH = logs_path)
# Log Info Message
logger.info("Info Message")
# Log Warning Message
logger.warning("Warning Message.")
# Log Error Message
logger.error("Error Message.")
# Log Critical Message
logger.critical("Critical Message.")
# Log Normal Message
logger.log("Normal Log Message.")
A list of a vailable configs are:
LOG_FILE_FORMAT: Log file format (default:%Y-%m-%d).LOG_FILE_PATH: Logs dir absolute path and it is required (default:LOG_MESSAGE_FORMAT: Log message format (default:{TYPE}: <{DATETIME}> {MESSAGE}).DATES_FORMAT: Dates format (default:%Y-%m-%d).DATETIME_FORMAT: Datetimes format (default:%Y-%m-%d %H:%M).PLATFORM_DATA: Whether to activate platform data (default:False).ALERT_STATUS: Email notification status (default:False).ALERT_SUBJECT: Email notification subject (default:My APP Alert).ALERT_EMAIL: Receiver Email or emails (format:[email protected]or[email protected],[email protected],..).ALERT_TYPES: Message types which will delivered to email (default:['critical', 'error']).MAILER_HOST: SMTP server (default:smtp.gmail.com).MAILER_PORT: SMTP server port (default:587).MAILER_USER: SMTP server user (default:None).MAILER_PWD: SMTP server password (default:None).MAILER_FROM: Sender email (default:[email protected]).
To set configs in initialization:
import pylogging
import os
# Logs dir absolute path
logs_path = os.path.dirname(os.path.abspath(__file__)) + '/logs/'
# Create a logger instance with custom configs
logger = pylogging.PyLogging(LOG_FILE_PATH = logs_path, LOG_FILE_FORMAT='%Y-%m-%d', DATES_FORMAT='%Y-%m-%d',..,..)
# So the form will be
logger = pylogging.PyLogging(LOG_KEY_1 = 'value', LOG_KEY_2='value',..,..)
To set a config value:
logger.setConfig('CONFIG_KEY', 'config_value')
To get a config value:
logger.getConfig('CONFIG_KEY')
To define a filter:
def customFilter(type, msg):
# Filter message text here
return msg
filterIden = logger.addFilter(customFilter)
To remove a filter:
logger.removeFilter(filterIden)
To define an action:
def customAction(type, msg):
# Perform any custom action here
pass
actionIden = logger.addAction(customAction)
To remove an action:
logger.removeAction(actionIden)
To enable email notifications:
import pylogging
import os
# Logs Dir Absolute Path
logs_path = os.path.dirname(os.path.abspath(__file__)) + '/logs/'
# Create Logger Instance
logger = pylogging.PyLogging(LOG_FILE_PATH = logs_path)
# Activate email alerting
logger.setConfig('ALERT_STATUS', True)
Then set your own configurations like so
# Set default message subject
logger.setConfig('ALERT_SUBJECT', "My APP Alert")
# Email to send message to
logger.setConfig('ALERT_EMAIL', '[email protected]')
# OR send message to many emails
logger.setConfig('ALERT_EMAIL', '[email protected],[email protected],[email protected]')
# Message types to receive alerts for
logger.setConfig('ALERT_TYPES', ['critical', 'error'])
# our own SMTP server (Library uses gmail)
logger.setConfig('MAILER_HOST', 'smtp.gmail.com')
# SMTP server port
logger.setConfig('MAILER_PORT', 587)
# SMTP server username (your gmail email)
logger.setConfig('MAILER_USER', '[email protected]')
# SMTP server password (your gmail password)
logger.setConfig('MAILER_PWD', 'gmailpass')
# Message from
logger.setConfig('MAILER_FROM', '[email protected]')
When you log messages, Messages of critical and error types will be delivered to emails:
# Log Info Message
logger.info("Info Message")
# Log Normal Message
logger.log("Normal Log Message.")
# Log Warning Message
logger.warning("Warning Message.")
# Log Error Message (with email notification)
logger.error("Error Message.")
# Log Critical Message (with email notification)
logger.critical("Critical Message.")
So if you like to send alert to [email protected] and your email password is dummypass the library configs will be:
logs_path = os.path.dirname(os.path.abspath(__file__)) + '/logs/'
logger = pylogging.PyLogging(LOG_FILE_PATH = logs_path)
logger.setConfig('ALERT_STATUS', True)
logger.setConfig('ALERT_SUBJECT', "My APP Alert")
logger.setConfig('ALERT_EMAIL', '[email protected]')
logger.setConfig('ALERT_TYPES', ['critical', 'error'])
logger.setConfig('MAILER_HOST', 'smtp.gmail.com')
logger.setConfig('MAILER_PORT', 587)
logger.setConfig('MAILER_USER', '[email protected]')
logger.setConfig('MAILER_PWD', 'dummypass')
logger.setConfig('MAILER_FROM', '[email protected]')
logger.info("Info Message")
logger.log("Normal Log Message.")
logger.warning("Warning Message.")
logger.error("Error Message.")
logger.critical("Critical Message.")
Since log file name passes through strftime(format), You can change file name into any valid time format string. For more info about format strings.
logger.setConfig('LOG_FILE_FORMAT', '%y-%m-%d')
By default you can use combination of available vars in log message format:
{TYPE}: Log message type.{DATE}: Log time date.{DATETIME}: Log time datetime.{MESSAGE}: Log message content.
The default format is {TYPE}: <{DATETIME}> {MESSAGE}, You can change like the following:
logger.setConfig('LOG_MESSAGE_FORMAT', '{DATE}: {TYPE}-{MESSAGE}')
To add additional platform vars. You need to activate them:
logger.setConfig('PLATFORM_DATA', True)
This will allow usage of:
PL_TYPE: The machine type, e.g.i386PL_NAME: The computer’s network name.PL_PROCESSOR: The (real) processor name, e.g.amdk6.PL_PY_BUILD_DATE: The Python build number.PL_PY_COMPILER: A string identifying the compiler used for compiling Python.PL_PY_RELEASE: The system’s release, e.g.2.2.0.PL_OS: The system/OS name, e.g.Linux,WindowsPL_TIMEZONE: The system timezone.
For example we can customize message format into:
logger.setConfig('PLATFORM_DATA', True)
logger.setConfig('LOG_MESSAGE_FORMAT', '{DATE}-{PL_OS}: {TYPE} - {MESSAGE}')
and so on.
