show-prediction-config - no valid command found?

[Nigel Williams <nigel.williams@xxxxxxxxxxx>]

Have I missed a step? Diskprediction module is not working for me.

root@cnx-11:/var/log/ceph# ceph device show-prediction-config
no valid command found; 10 closest matches:

root@cnx-11:/var/log/ceph# ceph mgr module ls
{
    "enabled_modules": [
        "dashboard",
        "diskprediction_cloud",
        "iostat",
        "pg_autoscaler",
        "prometheus",
        "restful"

    ],...

root@cnx-11:/var/log/ceph# ceph -v
ceph version 14.2.1 (d555a9489eb35f84f2e1ef49b77e19da9d113972) nautilus (stable)

One other failure I get for:

ceph device get-health-metrics INTEL_SSDPE2KE020T7_BTLE74200D8J2P0DGN

...

        "nvme_vendor": "intel",
        "dev": "/dev/nvme0n1",
        "error": "smartctl returned invalid JSON"

...

with smartmon 7.1

Using this version directly with the device and with JSON output parses ok (using an online parser).
