A simple go program which checks if your websites are running and runs forever (stop it with ctrl+c). It takes two optional arguments:
-interval=60
-urls='https://ma.rkus.io, https://www.uberswe.com'
You can run this by typing go run cmd/uptime/main.go -interval=5 -urls='https://ma.rkus.io, https://www.uberswe.com' in a terminal.
Logs will look like this:
