What are you looking to monitor?<p>I wrote a shell script recently that sends memory, cpu and hard drive statistics to firebase.com every minute via a cronjob and a simple front end site to display the results in angularjs 1.x - for such few connections, firebase is free.<p>I run it on 7 of our servers and it&#x27;s helped nicely<p>The shell script could easily have more added to it (status of httpd or nginx, mysql, etc...)<p>I leave it running on a 2nd monitor all day and with the data binding of firebase &#x2F; angularjs it refreshes automatically so i just watch it out of the corner of my eye.<p>I could throw it on git for you if you think it would help you.
