> **SILO behavior:** diagnostics run locally without SUBNET registration or automatic uploads. License info/unregister operate on local state; license update retains the explicit-file path. Online registration/renewal and uploads are disabled. Retained upstream syntax below does not enable those services. See [mcli compatibility](/compatibility/mcli/#subnet).

## Description {#description}

[`mc support profile`](#command-mc.support.profile) runs a system profile for your deployment. The results of the profile can provide insight into the MinIO server process running on a given node.

Diagnostic output stays local; SUBNET online services are disabled. Compatibility flags do not enable uploads.

## Examples {#examples}

### Fetch CPU Profiling {#fetch-cpu-profiling}

This command retrieves the CPU profile on a MinIO deployment with the alias `minio1`. The profile runs for the default of 10 seconds.

```shell
mc support profile --type cpu minio1/
```

### Fetch CPU, Memory, and Block Profiling Concurrently {#fetch-cpu-memory-and-block-profiling-concurrently}

This command fetches the profile of the CPU, memory, and block usage on the alias `minio2`. The profile runs for the default of 10 seconds.

```shell
mc support profile --type cpu,mem,block minio2/
```

### Fetch CPU, Memory, and Block Profiling Concurrently for 10 Minutes {#fetch-cpu-memory-and-block-profiling-concurrently-for-10-minutes}

This command fetches the profile of the CPU, memory, and block on the alias `minio3`. The profile runs for 10 minutes (600 seconds).

```shell
mc support profile --type cpu,mem,block --duration 600 minio3/
```

## Syntax {#syntax}

The [`mc support profile`](#command-mc.support.profile) command has the following syntax:

```shell
mc [GLOBALFLAGS] support profile       \
                         COMMAND       \
                         [--type]      \
                         [--airgap]    \
                         [--duration]  \
                         ALIAS
```

### Parameters {#parameters}

##### `--duration` {#mc.support.profile.-duration}

*mc-cmd*

*Optional*

Run profiling for the specified duration in seconds.

Use `--type <value>` where `<value>` is the number of seconds for the profile to run.

If not specified, the command collects data for 10 seconds.

##### `--type` {#mc.support.profile.-type}

*mc-cmd*

*Optional*

Specify the profile(s) to gather data for.

Use `--type <value>` where `<value>` is one or more comma-separated types of data to collect.

Valid types are:

- `cpu`
- `cpuio`
- `mem`
- `block`
- `mutex`
- `trace`
- `threads`
- `goroutines`

If not specified, the command collects data for CPU, memory, block, mutex, threads, and goroutines.

> [!WARNING]
> **Important**
>
> Do not use the `cpuio` or `trace` data types unless directed to by MinIO Support. These profiles require significant resources and may degrade cluster performance if used without guidance.

##### `--airgap` {#mc.support.profile.-airgap}

*mc-cmd*

*Optional*

Diagnostic output stays local; SUBNET online services are disabled. Compatibility flags do not enable uploads.

If the deployment is airgapped, but the local device where you are using the [minio client](/reference/minio-mc/#minio-client) has network access, you do not need to use the `--airgap` flag.

##### `ALIAS` {#mc.support.profile.ALIAS}

*mc-cmd*

*Required*

The [alias](/reference/minio-mc/mc-alias-set/#alias) of the MinIO deployment.

### Global Flags {#global-flags}

This command supports any of the [global flags](/reference/minio-mc/#minio-mc-global-options).
