How can I remotely monitor a Node process making sure it's running using outbound HTTP heartbeats vs inbound?

I would like the process itself to send heartbeats vs receiving them from services like Amazon Route 53 health checks.

I would like to avoid running a web server on that process.

    I ended up trying out Cronitor and so far it does the job. Pricing is a bit aggressive though. They do offer a free plan for one monitor but a hobbyist plan would have nailed their offering.

    Here is the code I use to send heartbeats.

    logger.captureException is a custom error reporting wrapper for Sentry.

    const sendHeartbeat = function() {
    request.get('https://cronitor.link/******/complete?auth_key=' + process.env.CRONITOR_AUTH_KEY, function(error, response, body) {
        if (error) {
            logger.captureException(error);
        }
        setTimeout(sendHeartbeat, 60 * 1000); // Run once per minute
    });
};
sendHeartbeat();
