Requirements

• crontab
• curl

Set Up

Clone or download the repository

If you choose to download the files, be sure to rename herokuapp_pinger_master to herokuapp_pinger.

Follow the steps below for installation

1. Move the repository folder inside the /Users/${USER}/ directory. This should be your ROOT user directory.

   It will look like:

   /Users/${USER}/herokuapp_pinger/

2. Navigate to the /herokuapp_pinger directory:

   cd /Users/${USER}/herokuapp_pinger/

   Open the script pinger.sh:

   vim pinger.sh

   Replace the DUMMY_USER_NAME on the line 30 with your user name like this: `export HOME=/Users/your_user_name'

3. Run the following command to give yourself access to execute pinger.sh and create folders to store logs.

   chmod +x pinger.sh && mkdir logs && mkdir csv_logs
   

   These two folders will be used to store logs. csv_logs folder will store logs in the form of CSV files and the logs folder will store them with .log extension

4. Add the hosts to the hosts_list.txt file inside herokuapp_pinger/script_data folder.

   Every host url should be on a new line

   NOTE: There should be a new empty line after the last host otherwise last entry in the file will not be read

   ALSO ANY NUMBER OF HOSTS CAN BE SPECIFIED IN THE hosts_list.txt file

5. Setup crontab like this:

   chrontab -e

   And add the following line to your chrontab editor.

   * * * * * /home/your_user_name/herokuapp_pinger/pinger.sh

   You should change the crontab schedule according to your needs as * * * * * will run the script every minute

   I ping my Heroku website every 30 minutes.

6. Test the script by running

   ./pinger.sh

   The script should: create two log files, run with no errors to the console, and display a notification with your hostname as the title and the status as the body.

   To turn off notifications, simply remove the display notifications (line 47) from .pinger.sh.
