Cluster diagnostics tool

The diagnostics subcommand of arvados-client performs a variety of checks to help confirm that your Arvados installation has been properly configured. It is extremely helpful to validate that your install is successful.

Depending on where you are running the installer, you need to provide -internal-client or -external-client.

• If you are running the diagnostics from one of the Arvados machines inside the private network, you want -internal-client.
• If you running the diagnostics from your workstation outside of the private network, you should use -external-client.

Here is an example of it in action:
