Ceph » mgr

Before PR https://github.com/ceph/ceph/pull/19235, ceph mgr module ls simply printed a short list of available and enabled modules that easily fit into the screen height.

However, after that PR, the output includes lots of metadata for disable modules, which makes hard to understand which modules are always on, available/disabled:

{
    "always_on_modules": [
        "balancer",
        "crash",
        "devicehealth",
        "orchestrator",
        "osd_support",
        "pg_autoscaler",
        "progress",
        "rbd_support",
        "status",
        "telemetry",
        "volumes" 
    ],
    "enabled_modules": [
        "cli",
        "dashboard",
        "iostat",
        "prometheus",
        "restful" 
    ],
    "disabled_modules": [
        {
            "name": "alerts",
            "can_run": true,
            "error_string": "",
            "module_options": {
                "interval": {
                    "name": "interval",
                    "type": "secs",
                    "level": "advanced",
                    "flags": 1,
                    "default_value": "60",
                    "min": "",
                    "max": "",
                    "enum_allowed": [],
                    "desc": "How frequently to reexamine health status",
                    "long_desc": "",
                    "tags": [],
                    "see_also": []
                },
                "log_level": {
...

A suggestion would be to only dump that metadata if 'detail' option is present (similar to other ceph commands).
