Python Logging to Syslog Server using RFC5424

in

Well, have no fear because I’m here to show you how to send those suckers over to the syslog server using RFC5424.

To begin with, make sure your syslog server is set up properly. If you don’t have one yet, well, that’s on you. But if you do, great! Now let’s get to the good stuff.

Step 1: Install the ‘pyrsyslog’ package using pip or whatever method you prefer. This will allow us to send our logs over to the syslog server in RFC5424 format.

# This script installs the 'pyrsyslog' package using pip, allowing logs to be sent to the syslog server in RFC5424 format.

# Install the 'pyrsyslog' package using pip
pip install pyrsyslog

Step 2: Create a log file that we want to send over to the syslog server. Let’s say it’s called ‘my_app.log’. Here’s an example of what you might put in there:

# Import the logging module to enable logging functionality
import logging
# Import the datetime module to get the current date and time
from datetime import datetime

# Set up the logging configuration, specifying the file name and the logging level
logging.basicConfig(filename='my_app.log', level=logging.DEBUG)

# Define a function to generate logs
def my_function():
    # Do some stuff here that generates logs
    # Use the logging.debug() method to log a debug message
    logging.debug('This is a debug message')
    # Use the logging.info() method to log an info message
    logging.info('This is an info message')
    # Use the logging.warning() method to log a warning message
    logging.warning('This is a warning message')
    # Use the logging.error() method to log an error message
    logging.error('This is an error message')
    # Use the logging.critical() method to log a critical message
    logging.critical('This is a critical message')

# Call the function to generate logs
my_function()

Step 3: Modify the ‘basicConfig’ function to include the syslog server details and RFC5424 format. Here’s what it might look like:

# Import necessary libraries
import logging # Import the logging library
from datetime import datetime # Import the datetime library
import pyrsyslog # Import the pyrsyslog library for syslog functionality

# Clear any existing handlers from the logger
logging.getLogger().handlers = []

# Set up the syslog server details and RFC5424 format
handler = pyrsyslog.SysLogHandler('192.168.0.1', 'my_app') # Create a SysLogHandler object with the IP address and application name
formatter = logging.Formatter(fmt='%(asctime)s %(levelname)-7s [%(processName)s] %(message)s') # Create a formatter object with the desired format for the logs
handler.setLevel(logging.DEBUG) # Set the logging level for the handler to DEBUG
handler.setFormatter(formatter) # Set the formatter for the handler

# Add the syslog handler to our logger object
logger = logging.getLogger(__name__) # Create a logger object with the name of the current module
logger.addHandler(handler) # Add the handler to the logger object

def my_function():
    # Do some stuff here that generates logs
    logging.debug('This is a debug message') # Log a debug message
    logging.info('This is an info message') # Log an info message
    logging.warning('This is a warning message') # Log a warning message
    logging.error('This is an error message') # Log an error message
    logging.critical('This is a critical message') # Log a critical message

my_function() # Call the function to generate logs

Step 4: Run your Python script and watch the logs magically appear on your syslog server!

And there you have it, Sending your Python logs to a syslog server using RFC5424 format.
