What is monitor_internet_connection?
It is a Python module to monitor the uptime of the Internet connection - that is to say to monitor that an external IP address is always reachable.
Why should I use monitor_internet_connection?
If you have automated long-running processes/programs/activities on your computer that requires Internet connectivity, there is nothing worse than coming back the next hour/day/week/whenever to review the logs/progress and find out that the program(s) failed or data is missing because of lost Internet connectivity. What is worse - you may not know exactly when Internet connectivity was lost. Thus, will you need to rerun the entire program/process? Or just a part of it? and so on.
The Python module monitor_internet_connection
is a solution to this problem in that it monitors Internet connectivity in real-time, displaying on the console/terminal and recording to a log file: the start time, the end time and the duration of any Internet connectivity downtime. You may simply run this module in a console/terminal and leave it running for days/weeks on end.
What does monitor_internet_connection do?
Every X seconds (default polling frequency is 1 second), the program monitors whether the Internet connection is alive and an external IP address is reachable.
If the Internet is unreachable:
-
The first observed time of failure is logged.
-
Every one-minute interval of subsequent unavailability is logged. The one-minute logs can be useful as a proxy indicator of whether the computer lost power or just the Internet connection was unavailable.
-
When Internet connectivity is restored, the first observed time of restoration is logged.
-
Finally, the total time duration of the Internet unavailability is logged.
Log File
-
The log file is called
internet_monitor.log
. -
The log file is written to the current working folder.
-
The log file is always appended to, never overwritten.
-
The information written to the log file is also displayed on the console/terminal.
-
The log file may be disabled via a command line parameter. See Usage below.
Prerequisites
You must have Python 3.6 or higher installed.
Installation
pip install monitor_internet_connection
QuickStart
python -m monitor_internet_connection
How do I exit the program
To exit the program, simply press Ctrl-C
inside the console/terminal. This will cause the program to exit gracefully.
Usage
