provides one of the simplest ways to monitor your servers and processes for free. If I want to monitor a service, I can monitor it by simply sending an HTTP POST request to my heartbeat.sh server, and voila, my service is being monitored! I will show you how to this in three easy steps. Heartbeat.sh ( : ) Disclaimer The author is the developer who built heartbeat.sh Step 1: Create your server This is as simple as it gets. Just go to , enter a name for your server an click on the big button! will then create a server for you, with your server name as a subdomain, and redirect you to your new dashboard. heartbeat.sh Create Server Heartbeat.sh For example. Say I wanted to create a monitoring server named . I simply go to the home page, enter in the text box and click on create-server. hn-example heartbeat.sh hn-example then automatically redirects me to which is the dashboard for my new monitoring server. Heartbeat.sh hn-example.heartbeat.sh Step 2: Start sending heartbeats Now that I have a monitoring server, I better start using it. Using the server is as simple as sending a heartbeat with a post request to . https://{my-subdomain}.heartbeat.sh/beat/{heartbeat-name} I will use as an example, but that's not the only way. You can use any tool capable of sending http requests, like for JavaScript or for Python. also has open source and libraries available on their . curl axios requests Heartbeat.sh JavaScript Python github profile ❯ curl -X POST 'https://hn-example.heartbeat.sh/beat/example' The server then replied with this JSON object: { : , : , : , : , : , : } "Name" "example" "Warning" 60 "Error" 300 "Age" 0 "Status" "OK" "LastBeat" "2020-11-13T08:12:56.447936897Z" The and fields mean that my heartbeat will go into Warning status after 60 seconds after the last POST request, and into Error status after 300 seconds (5 minutes). If I want to make the timeouts 90 seconds and 1 hour respectively, I can just add that to the request query string: Warning Error ❯ curl -X POST 'https://hn-example.heartbeat.sh/beat/example?warning=1m30&error=1h' To which the server replies with: { : , : , : , : , : , : } "Name" "example" "Warning" 90 "Error" 3600 "Age" 0 "Status" "OK" "LastBeat" "2020-11-13T08:23:02.738496856Z" Every POST request will update the heartbeat. If I have a script that must run every day, I can send a heartbeat at the end of the script with a warning and error timeout of 1 day each. The heartbeat will then timeout if my script missed a day. Step 3: Check your heartbeats My dashboard shows my heartbeats and their statuses. It automatically refreshes every minute, so I can display it on a screen where the color changes will quickly tell me if there is a problem. I can also get my heartbeat statuses programmatically by simply sending a GET request: ❯ curl -X GET 'https://hn-example.heartbeat.sh/beat/example' { : , : , : , : , : , : } "Name" "example" "Warning" 90 "Error" 3600 "Age" 527 "Status" "WARNING" "LastBeat" "2020-11-13T08:23:02Z" Or to get a list of all my beats: curl -X GET 'https://hn-example.heartbeat.sh/heartbeats' { : [
        { : , : , : , : , : , : }
    ]
} "Heartbeats" "Name" "example" "Warning" 90 "Error" 3600 "Age" 669 "Status" "WARNING" "LastBeat" "2020-11-13T08:23:02Z" This is the simplest monitoring set-up I know of. I use it for some of my hobby projects and even at work. made it very easy for me to automate my daily checks. Now I spend less time baby sitting my projects and more time improving them.
