Host monitor

Requires Datadog Agent version >= 5.0.0.


Every Datadog Agent collection reports a heartbeat called datadog.agent.up with a status UP. You can monitor this heartbeat across one or more hosts.


  1. Select your host by name or tag(s). Providing a tag monitors every host that has that tag or tag combination.
