What is Python Syslog? Explained with Different methods

Hello geeks and welcome in today’s article, we will cover Python Syslog. Along with that, for proper understanding, we will look at different methods and also some sample code. Before moving that ahead let us first understand Syslog through its definition. The module provides an interface to the Unix Syslog library. Here Unix is an OS developed for multiuser and multitasking computers. A module named SysLogHandler is available in logging.handlers, a pure python library that can speak to the Syslog server.

Different Methods for Python Syslog

1. SYSLOG.SYLOG(MESSAGE,PRIORITY)

This function sends a string message to the system logger. Here logger keeps track of events when the software runs. Here the priority argument is optional and defaults to log_info, and it determines the priority.

2. SYSLOG.OPENLOG

This is used as an subsequent of syslog call. It takes an ident argument which of string type.

3. SYSLOG.CLOSELOG

This method is used for the purpose of resetting the syslog module.

4. SYSLOG.SETLOGMASK

This method is used to set up the priority mask to maskpri, It returns the previous mask value. When there is no priority maskpri is ignored.

Sample Code Covering Various Syslog Methods

In this section we will look at some sample codes in which we have will use the various methods discussed in the above section.

import syslog
import sys

syslog.openlog(sys.argv[0])

syslog.syslog(syslog.LOG_NOTICE, "notice-1")
syslog.syslog(syslog.LOG_NOTICE, "notice-2")

syslog.closelog()

Here above we can see the sample code. Here at first, we have imported the Syslog module. Along with that we have imported the sys which means system-specific parameters. Next, we have used openlog with a command sys. argv[0]. This command is a list that contains the command-line argument passed to the script. Next, we have a Syslog method and closed with a close log command.

SysLogHandler

As discussed at the start of the article it is a method available in logging. handlers. This particular method supports sending a message to a remote or Unix Syslog. Let us look at an example in order for a better understanding.

import logging
import logging.handlers
import sys

logger = logging.getLogger()
logger.setLevel(logging.INFO)
syslog = logging.handlers.SysLogHandler(address=("localhost", 8000))
logger.addHandler(syslog)
print (logger.handlers)

Output

Python Syslog

Here at first, we have imported the logging module, an in-built module of python. Then we have imported logging handlers, which sends the log records to the appropriate destination. Next, we have imported SYS, as discussed above. Then in the next step, we have created an object with getlogger. Then in the next step, we have used the setlevel command. What it does is that all messages before this level are ignored. Then we have used our Sysloghandeler command. Next, we have used addHandler to add a specific handler to our logger “syslog” in our case. Finally, we have just used a print statement to print that handler.

Difference Between Syslog and Logging

This section will discuss the basic difference between the Syslog and logging in python. Here we have discussed Syslog in detail but before comparing the 2, let us look at the logging definition. It is an in-built module of python that helps the programmer keep track of events that are taking place. The basic difference between the 2 is that Syslog is more powerful, whereas the logging is easy and used for simple purposes. Another advantage of Syslog over logging is that it can send log lines to a different computer to have it logged there.

Conclusion

In this article, we covered Python Syslog. We looked at its definition, use, and the different methods associated with it. In the end, we can conclude that it provides us with an interface of Unix.

I hope this article was able to clear all doubts. But in case you have any unsolved queries feel free to write them below in the comment section. Done reading this why not look at the FizzBuzz challenge next.
