A Python script that checks the HTTP status code of a website and reports the outcome via Slack
This requires a few pre-requistes:
- pip
- requests
Install Python 2 and 3 versions in your command line with:
$ sudo apt-get install -y python-pip python3-pip
Install in your command line with:
$ sudo pip install requests
To clone this repo, run the following command in your command line:
$ git clone https://github.com/raspberrycoulis/pi-ping-slack.git
To use this script, you'll need to make a few changes to the variables used.
This is the website you want to check the status of. Replace https://www.google.co.uk with your chosen website.
The name of the website - this will form part of the Slack message and is really a vanity variable, but it's nice to use!
The time to wait between status checks in seconds. By default this is set to 1800 seconds (which is 30 minutes), but you can adjust this if you prefer.
This will be your Slack incoming webhook - you can get a full walkthrough of this via Slack's documentation.
This is the colour displayed in the Slack message for your "OK" message - i.e the website is up and running. Define a custom colour using any colour hex code. Default is #74a727 (Raspberry Pi Green).
This is the colour displayed in the Slack message for your "Uh oh!" message - i.e the website is offline. Define a custom colour using any colour hex code. Default is #971a1a (Raspberry Coulis Red).
Before running the script, make sure it is executable by running (assuming you have cloned this in your home directory):
$ cd pi-ping-slack
$ chmod +x pi-ping-slack.py
Test out the script by running:
$ ./pi-ping-slack.py
If all goes well, you should have a Slack notification that looks like this:
The script is set to check the status of your set website every 30 minutes (1800 seconds), but to run this on boot you can do so using systemd:
This will tell the Pi to run your script on boot:
sudo nano /lib/systemd/system/pi-ping-slack.service
Then add the following text to your file (you may need to adjust the path for your pi-ping-slack.py script depending on where it is located (the part /home/pi/Pi-Ping/pi-ping.py):
[Unit]
Description=Pi-Ping via Slack service by Raspberry Coulis
After=multi-user.target
[Service]
Type=idle
ExecStart=/usr/bin/python /home/pi/pi-ping-slack/pi-ping-slack.py
[Install]
WantedBy=multi-user.target
Exit, ctrl + x, and save y to create the service unit file.
Make sure that the permissions are set correctly:
sudo chmod 644 /lib/systemd/system/pi-ping-slack.service
Make sure that systemd can use your newly created unit file:
sudo systemctl daemon-reload
sudo systemctl enable pi-ping-slack.service
Reboot the Pi to test via sudo reboot.
Check that the service has started by running:
sudo systemctl status pi-ping-slack.service
If done correctly, you should see that your pi-ping-slack.py script is now running!
