Monitor services for their availability with active probing. Given a list of URLs, Heartbeat asks the simple question: Are you alive? Heartbeat ships this information and response time to the rest of the Elastic Stack for further analysis.
Heartbeat is a lightweight daemon that you install on a remote server to periodically check the status of your services and determine whether they are available. Unlike Metricbeat, which only tells you if your servers are up or down, Heartbeat tells you whether your services are reachable.
Heartbeat is useful when you need to verify that you’re meeting your service level agreements for service uptime. It’s also useful for other scenarios, such as security use cases, when you need to verify that no one from the outside can access services on your private enterprise server.
You can configure Heartbeat to ping all DNS-resolvable IP addresses for a specified hostname. That way, you can check all services that are load-balanced to see if they are available.
