# `otelcol.receiver.vcenter`

> **EXPERIMENTAL**: This is an [experimental](/docs/release-life-cycle/) component. Experimental components are subject to frequent breaking changes, and may be removed with no equivalent replacement. To enable and use an experimental component, you must set the `stability.level` [flag](/docs/alloy/latest/reference/cli/run/) to `experimental`.

`otelcol.receiver.vcenter` accepts metrics from a vCenter or ESXi host running VMware vSphere APIs and forwards it to other `otelcol.*` components.

> Note
> 
> `otelcol.receiver.vcenter` is a wrapper over the upstream OpenTelemetry Collector [`vcenter`](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.147.0/receiver/vcenterreceiver) receiver. Bug reports or feature requests will be redirected to the upstream repository, if necessary.

You can specify multiple `otelcol.receiver.vcenter` components by giving them different labels.

The full list of metrics that can be collected can be found in [vcenter receiver documentation](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.147.0/receiver/vcenterreceiver/documentation.md).

## Prerequisites

This receiver has been built to support ESXi and vCenter versions:

- 8
- 7.0

A “Read Only” user assigned to a vSphere with permissions to the vCenter server, cluster, and all subsequent resources being monitored must be specified in order for the receiver to retrieve information about them.

## Usage

Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```alloy
otelcol.receiver.vcenter "<LABEL>" {
  endpoint = "<VCENTER_ENDPOINT>"
  username = "<VCENTER_USERNAME>"
  password = "<VCENTER_PASSWORD>"

  output {
    metrics = [...]
  }
}
```

## Arguments

You can use the following arguments with `otelcol.receiver.vcenter`:

|-----------------------|------------|---------------------------------------------------------------------------|---------|----------|
| `endpoint`            | `string`   | Endpoint to a vCenter Server or ESXi host which has the SDK path enabled. |         | yes      |
| `username`            | `string`   | Username to use for authentication.                                       |         | yes      |

| `collection_interval` | `duration` | Defines how often to collect metrics.                                     | `"1m"`  | no       |
| `initial_delay`       | `duration` | Defines how long this receiver waits before starting.                     | `"1s"`  | no       |
| `timeout`             | `duration` | Defines the timeout for the underlying HTTP client.                       | `"0s"`  | no       |

`endpoint` has the format `<protocol>://<hostname>`. For example, `https://vcsa.hostname.localnet`.

## Blocks

You can use the following blocks with `otelcol.receiver.vcenter`:

No valid configuration blocks found.

### `output`

Required

The `output` block configures a set of components to forward resulting telemetry data to.

The following arguments are supported:

Expand table

| Name      | Type                     | Description                           | Default | Required |
|-----------|--------------------------|---------------------------------------|---------|----------|
| `logs`    | `list(otelcol.Consumer)` | List of consumers to send logs to.    | `[]`    | no       |
| `metrics` | `list(otelcol.Consumer)` | List of consumers to send metrics to. | `[]`    | no       |
| `traces`  | `list(otelcol.Consumer)` | List of consumers to send traces to.  | `[]`    | no       |

You must specify the `output` block, but all its arguments are optional. By default, telemetry data is dropped. Configure the `metrics`, `logs`, and `traces` arguments accordingly to send telemetry data to other components.

### `debug_metrics`

The `debug_metrics` block configures the metrics that this component generates to monitor its state.

The following arguments are supported:

Expand table

| Name                               | Type      | Description                                          | Default | Required |
|------------------------------------|-----------|------------------------------------------------------|---------|----------|
| `disable_high_cardinality_metrics` | `boolean` | Whether to disable certain high cardinality metrics. | `true`  | no       |

`disable_high_cardinality_metrics` is the Alloy equivalent to the `telemetry.disableHighCardinalityMetrics` feature gate in the OpenTelemetry Collector. It removes attributes that could cause high cardinality metrics. For example, attributes with IP addresses and port numbers in metrics about HTTP and gRPC connections are removed.

> Note
> 
> If configured, `disable_high_cardinality_metrics` only applies to `otelcol.exporter.*` and `otelcol.receiver.*` components.

The following arguments are supported:

If the server doesn’t support TLS, you must set the `insecure` argument to `true`.

To disable `tls` for connections to the server, set the `insecure` argument to `true`.

If you set `reload_interval` to `"0s"`, the certificate never reloaded.

The following pairs of arguments are mutually exclusive and can’t both be set simultaneously:

- `ca_pem` and `ca_file`
- `cert_pem` and `cert_file`
- `key_pem` and `key_file`

If `cipher_suites` is left blank, a safe default list is used. Refer to the [Go TLS documentation](https://go.dev/src/crypto/tls/cipher_suites.go) for a list of supported cipher suites.

The `curve_preferences` argument determines the set of [elliptic curves](https://go.dev/src/crypto/tls/common.go#L138) to prefer during a handshake in preference order. If not provided, a default list is used. The set of elliptic curves available are `X25519`, `P521`, `P256`, and `P384`.

### `tpm`

The `tpm` block configures retrieving the TLS `key_file` from a trusted device.

The following arguments are supported:

| Name         | Type     | Description                                                        | Default | Required |
|--------------|----------|--------------------------------------------------------------------|---------|----------|
| `auth`       | `string` | The authorization value used to authenticate the TPM device.       | `""`    | no       |
| `enabled`    | `bool`   | Load the `tls.key_file` from TPM.                                  | `false` | no       |
| `owner_auth` | `string` | The owner authorization value used to authenticate the TPM device. | `""`    | no       |
| `path`       | `string` | Path to the TPM device or Unix domain socket.                      | `""`    | no       |

The [trusted platform module](https://trustedcomputinggroup.org/resource/trusted-platform-module-tpm-summary/) (TPM) configuration can be used for loading TLS key from TPM. Currently only TSS2 format is supported.

The `path` attribute is not supported on Windows.

In the following example, the private key `my-tss2-key.key` in TSS2 format is loaded from the TPM device `/dev/tmprm0`:

            enabled = true
            path = "/dev/tpmrm0"
        }
    }
}
```

## Exported fields

`otelcol.receiver.vcenter` doesn’t export any fields.

## Component health

`otelcol.receiver.vcenter` is only reported as unhealthy if given an invalid configuration.

## Debug information

`otelcol.receiver.vcenter` doesn’t expose any component-specific debug information.

## Example

This example forwards received telemetry data through a batch processor before finally sending it to an OTLP-capable endpoint:

Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```alloy
otelcol.receiver.vcenter "default" {
  endpoint = "http://localhost:15672"
  username = "otelu"
  password = "password"

  output {
    metrics = [otelcol.processor.batch.default.input]
  }
}

otelcol.processor.batch "default" {
  output {
    metrics = [otelcol.exporter.otlphttp.default.input]
  }
}

otelcol.exporter.otlphttp "default" {
  client {
    endpoint = sys.env("<OTLP_ENDPOINT>")
  }
}
```
