swim-cli sync -h warp://localhost:9001 -n /machine/my-machine -l statusHistory
swim-cli sync -h warp://localhost:9001 -n /machine/my-machine -l systemInfo
swim-cli sync -h warp://localhost:9001 -n /machine/my-machine -l usage
swim-cli sync -h warp://localhost:9001 -n /machine/my-machine -l processes

Streaming APIs for a Cluster

swim-cli sync -h warp://localhost:9001 -n /cluster/abc -l machines
swim-cli sync -h warp://localhost:9001 -n /cluster/abc -l status
swim-cli sync -h warp://localhost:9001 -n /cluster/abc -l statusHistory

Running the UI

Now, you can view the UI by appending /ui to the host address using the HTTP or HTTPS protocol, such as http://localhost:9001/ui.
