This is a small script I used to check if my web page is up and running. It is run in a cron job every 10 minutes.

I use the SendGrid API to mail myself an alert if the page is down. I figured this would be easier than setting up SMTP myself.

If you wish to run the script yourself, here are some instructions.

Install

• Go programming language: https://golang.org/doc/install
• SendGrid Go package: https://github.com/sendgrid/sendgrid-go
• SendGrid API key: https://sendgrid.com/beta/settings/api_key

You must set your SendGrid API key as an environment variable.

export SENDGRID_API_KEY=some_sample_123

Then you can build the binary using go build.
