./heartbeat --host 127.0.0.1 --port 10000

Connects to a node at the given address and verifies it is alive and responding.

Typical Workflow

Use heartbeat in monitoring scripts to check node health:

if ./heartbeat --host 127.0.0.1 --port 10000; then
    echo "Node is healthy"
else
    echo "Node is DOWN"  # non-zero exit on failure
fi

--host <ip>	Target node IP address.
--port <port>	Target node inter-node port.

What It Checks

• The target node responds to a ping message.
• The target node's identification is valid.
