If line and any(re.findall('|'.join(self.exceptionPattern), line, flags=re.I | re. # The line is scanned from left to right and matches are returned in the oder found. # Return all non-overlapping matches of the values specified in the Exception Pattern. # Remove leading and trailing whitespaces including newlines. # Meaning by that it will start from the point where it was last stopped.įor num, line in enumerate(Pygtail(path), 1): # Read the lines of the file (specified in the path) that have not been read yet # Get current date and time according to the specified format. # Loading the package called re from the RegEx Module in order to work with Regular Expressionsĭef checkForException(self, event, path): Next, let's define a checking mechanism, this mechanism will leverage the modules pygtail and re in order to pinpoint the observations based on the parameter EXCEPTION_PATTERN we just defined in config.py: import datetime
The parameters in config.py will be the default ones, later on, in the script, we can override them if we want. LOG_FILES_EXTENSIONS = ('.txt', '.log', '.trc')ĮXCEPTION_PATTERN = Now, well create the actual service using a class: class BHServerSvc (win32serviceutil.ServiceFramework): svcname 'BlackHatService'. # Check The WATCH_DIRECTORY and its children Here, we do our imports, set the source directory for the script file, and then set the target directory where the service will run it. # Directory To Watch, If not specified, the following value will be considered explicitly.

To get started, let's install the requirements: $ pip3 install Pygtail=0.11.1 watchdog=2.1.1įirst, let's define the configuration parameters for our application within config.py: # Application configuration File We will be using watchdog and pygtail libraries to detect the changes occurring, there is also a Flask, Redis, and SocketIO version where a GUI web app is created for the same purpose, you can always refer to it here. On the other hand, all the lines within these files that don’t match the specified patterns are considered outliers and are abandoned in our analysis. Whenever a change occurs, the modified or newly created files of predefined types will be processed in a timely manner to retrieve the lines meeting specified patterns.

In this tutorial, you will learn how to create a watchdog in Python we will explain how to detect changes in a particular directory (Let’s suppose the directory hosting the logs of your application(s)).
They need speed, regardless of the amount of data they are collecting and querying. When an issue occurs, they cannot afford to wait for a minute or two until a query returns results. Nowadays, application support engineers need to be able to easily access and analyze the huge volumes of log data their applications and infrastructure are generating.

As much as we’d like our software to be perfect, issues will always arise therefore it’s important to have a robust monitoring and logging in place to control and manage the inevitable chaos.
Within software development, application logging plays a key role. Disclosure: This post may contain affiliate links, meaning when you click the links and make a purchase, we receive a commission.
