What is the default health check timeout in Consul?

By default, script checks are configured with a timeout equal to 30 seconds.

What happens if Consul server goes down?

If the failed server is recoverable, the best option is to bring it back online and have it rejoin the cluster with the same IP address. This will return the cluster to a fully healthy state. Similarly, if you need to rebuild a new Consul server, to replace the failed node, you may wish to do that immediately.

What is a Consul agent?

The consul agent command is the heart of Consul: it runs the agent that performs the important task of maintaining membership information, running checks, announcing services, handling queries, etc. Due to the power and flexibility of this command, the Consul agent is documented in its own section.
