## Local diagnostics {#description}

`mcli support` retains SILO diagnostics without a MinIO SUBNET subscription.
Administrators control generated files and deliberate sharing.

## Subcommands {#subcommands}

| Command           | SILO behavior                            |
| ----------------- | ---------------------------------------- |
| `diag`            | Generate a local health report           |
| `perf`            | Run performance tests with local results |
| `profile`         | Server profiling and local output        |
| `inspect`         | Inspect object metadata                  |
| `top`             | Observe live server activity             |
| `callhome enable` | Disabled, exit 1; disable/status remain  |
| `proxy set`       | Disabled, exit 1; remove remains         |
| `upload`          | Disabled, exit 1                         |

Use `mcli support COMMAND --help` for flags. Diagnostics still require the
corresponding administrative permissions on the target SILO server.
