The Basics

Every stream has two basic parts

• data-in - A chunk or EOF enters the stream
• data-out - A chunk or EOF leaves the stream

I'm combining both "data" and "end" events since "end" is just a special data packet signifying the end of the stream.

# /etc/monit/monitrc (excerpt)

check process node-app with pidfile /var/run/node-app.pid
    start program = "/sbin/start node-app" with timeout 5 seconds
    stop program  = "/sbin/stop node-app"
    if failed port 3000 protocol HTTP
        request /
        with timeout 3 seconds
        then restart
    if cpu > 80% for 10 cycles then restart
