# otelcol.processor.transform

> **EXPERIMENTAL**: This is an [experimental](/docs/agent/v0.43/stability/#experimental) component. Experimental components are subject to frequent breaking changes, and may be removed with no equivalent replacement.

`otelcol.processor.transform` accepts telemetry data from other `otelcol` components and modifies it using the [OpenTelemetry Transformation Language (OTTL)](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/README.md). OTTL statements consist of [OTTL functions](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/ottlfuncs/README.md), which act on paths. A path is a reference to a telemetry data such as:

- Resource attributes.
- Instrumentation scope name.
- Span attributes.

In addition to the [standard OTTL functions](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/ottlfuncs/README.md), there is also a set of metrics-only functions:

- [convert\_sum\_to\_gauge](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.96.0/processor/transformprocessor#convert_sum_to_gauge)
- [convert\_gauge\_to\_sum](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.96.0/processor/transformprocessor#convert_gauge_to_sum)
- [convert\_summary\_count\_val\_to\_sum](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.96.0/processor/transformprocessor#convert_summary_count_val_to_sum)
- [convert\_summary\_sum\_val\_to\_sum](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.96.0/processor/transformprocessor#convert_summary_sum_val_to_sum)
- [copy\_metric](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.96.0/processor/transformprocessor#copy_metric)

[OTTL](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/README.md) statements can also contain constructs such as:

- [Booleans](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.96.0/pkg/ottl#booleans):
  
  - `not true`
  - `not IsMatch(name, "http_.*")`
- [Boolean Expressions](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.96.0/pkg/ottl#boolean-expressions) consisting of a `where` followed by one or more booleans:
  
  - `set(attributes["whose_fault"], "ours") where attributes["http.status"] == 500`
  - `set(attributes["whose_fault"], "theirs") where attributes["http.status"] == 400 or attributes["http.status"] == 404`
- [Math expressions](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.96.0/pkg/ottl#math-expressions):
  
  - `1 + 1`
  - `end_time_unix_nano - start_time_unix_nano`
  - `sum([1, 2, 3, 4]) + (10 / 1) - 1`

> Note
> 
> There are two ways of inputting strings in River configuration files:
> 
> - Using quotation marks ( [normal River strings](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#strings)). Characters such as `\` and `"` must be escaped by preceding them with a `\` character.
> - Using backticks ( [raw River strings](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#raw-strings)). No characters must be escaped. However, it’s not possible to have backticks inside the string.
> 
> For example, the OTTL statement `set(description, "Sum") where type == "Sum"` can be written as:
> 
> - A normal River string: `"set(description, \"Sum\") where type == \"Sum\""`.
> - A raw River string: `` `set(description, "Sum") where type == "Sum"` ``.
> 
> Raw strings are generally more convenient for writing OTTL statements.

> Note
> 
> `otelcol.processor.transform` is a wrapper over the upstream OpenTelemetry Collector `transform` processor. If necessary, bug reports or feature requests will be redirected to the upstream repository.

You can specify multiple `otelcol.processor.transform` components by giving them different labels.

> Warning
> 
> `otelcol.processor.transform` allows you to modify all aspects of your telemetry. Some specific risks are given below, but this is not an exhaustive list. It is important to understand your data before using this processor.
> 
> - [Unsound Transformations](https://github.com/open-telemetry/opentelemetry-collector/blob/v0.96.0/docs/standard-warnings.md#unsound-transformations): Transformations between metric data types are not defined in the [metrics data model](https://github.com/open-telemetry/opentelemetry-specification/blob/main//specification/metrics/data-model.md). To use these functions, you must understand the incoming data and know that it can be meaningfully converted to a new metric data type or can be used to create new metrics.
>   
>   - Although OTTL allows you to use the `set` function with `metric.data_type`, its implementation in the transform processor is a [no-op](https://en.wikipedia.org/wiki/NOP_%28code%29). To modify a data type, you must use a specific function such as `convert_gauge_to_sum`.
> - [Identity Conflict](https://github.com/open-telemetry/opentelemetry-collector/blob/v0.96.0/docs/standard-warnings.md#identity-conflict): Transformation of metrics can potentially affect a metric’s identity, leading to an Identity Crisis. Be especially cautious when transforming a metric name and when reducing or changing existing attributes. Adding new attributes is safe.
> - [Orphaned Telemetry](https://github.com/open-telemetry/opentelemetry-collector/blob/v0.96.0/docs/standard-warnings.md#orphaned-telemetry): The processor allows you to modify `span_id`, `trace_id`, and `parent_span_id` for traces and `span_id`, and `trace_id` logs. Modifying these fields could lead to orphaned spans or logs.

## Usage

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

```alloy
otelcol.processor.transform "LABEL" {
  output {
    metrics = [...]
    logs    = [...]
    traces  = [...]
  }
}
```

## Arguments

`otelcol.processor.transform` supports the following arguments:

Expand table

| Name         | Type     | Description                                                        | Default       | Required |
|--------------|----------|--------------------------------------------------------------------|---------------|----------|
| `error_mode` | `string` | How to react to errors if they occur while processing a statement. | `"propagate"` | no       |

The supported values for `error_mode` are:

See [OTTL Context](#ottl-context) for more information about how ot use contexts.

### OTTL Context

Each context allows the transformation of its type of telemetry. For example, statements associated with a `resource` context will be able to transform the resource’s `attributes` and `dropped_attributes_count`.

Each type of `context` defines its own paths and enums specific to that context. Refer to the OpenTelemetry documentation for a list of paths and enums for each context:

- [resource](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/contexts/ottlresource/README.md)
- [scope](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/contexts/ottlscope/README.md)
- [span](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/contexts/ottlspan/README.md)
- [spanevent](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/contexts/ottlspanevent/README.md)
- [log](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/contexts/ottllog/README.md)
- [metric](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/contexts/ottlmetric/README.md)
- [datapoint](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.96.0/pkg/ottl/contexts/ottldatapoint/README.md)

Contexts **NEVER** supply access to individual items “lower” in the protobuf definition.

- This means statements associated to a `resource` **WILL NOT** be able to access the underlying instrumentation scopes.
- This means statements associated to a `scope` **WILL NOT** be able to access the underlying telemetry slices (spans, metrics, or logs).
- Similarly, statements associated to a `metric` **WILL NOT** be able to access individual datapoints, but can access the entire datapoints slice.
- Similarly, statements associated to a `span` **WILL NOT** be able to access individual SpanEvents, but can access the entire SpanEvents slice.

For practical purposes, this means that a context cannot make decisions on its telemetry based on telemetry “lower” in the structure. For example, **the following context statement is not possible** because it attempts to use individual datapoint attributes in the condition of a statement associated to a `metric`:

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

```alloy
metric_statements {
  context = "metric"
  statements = [
    "set(description, \"test passed\") where datapoints.attributes[\"test\"] == \"pass\"",
  ]
}
```

Context **ALWAYS** supply access to the items “higher” in the protobuf definition that are associated to the telemetry being transformed.

- This means that statements associated to a `datapoint` have access to a datapoint’s metric, instrumentation scope, and resource.
- This means that statements associated to a `spanevent` have access to a spanevent’s span, instrumentation scope, and resource.
- This means that statements associated to a `span`/`metric`/`log` have access to the telemetry’s instrumentation scope, and resource.
- This means that statements associated to a `scope` have access to the scope’s resource.

For example, **the following context statement is possible** because `datapoint` statements can access the datapoint’s metric.

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

```alloy
metric_statements {
  context = "datapoint"
  statements = [
    "set(metric.description, \"test passed\") where attributes[\"test\"] == \"pass\"",
  ]
}
```

The protobuf definitions for OTLP signals are maintained on GitHub:

- [traces](https://github.com/open-telemetry/opentelemetry-proto/blob/v1.0.0/opentelemetry/proto/trace/v1/trace.proto)
- [metrics](https://github.com/open-telemetry/opentelemetry-proto/blob/v1.0.0/opentelemetry/proto/metrics/v1/metrics.proto)
- [logs](https://github.com/open-telemetry/opentelemetry-proto/blob/v1.0.0/opentelemetry/proto/logs/v1/logs.proto)

Whenever possible, associate your statements to the context which the statement intens to transform. The contexts are nested, and the higher-level contexts don’t have to iterate through any of the contexts at a lower level. For example, although you can modify resource attributes associated to a span using the `span` context, it is more efficient to use the `resource` context.

### output block

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.

## Exported fields

The following fields are exported and can be referenced by other components:

Expand table

| Name    | Type               | Description                                                      |
|---------|--------------------|------------------------------------------------------------------|
| `input` | `otelcol.Consumer` | A value that other components can use to send telemetry data to. |

`input` accepts `otelcol.Consumer` data for any telemetry signal (metrics, logs, or traces).

## Component health

`otelcol.processor.transform` is only reported as unhealthy if given an invalid configuration.

## Debug information

`otelcol.processor.transform` does not expose any component-specific debug information.

## Debug metrics

`otelcol.processor.transform` does not expose any component-specific debug metrics.

## Examples

### Perform a transformation if an attribute does not exist

This example sets the attribute `test` to `pass` if the attribute `test` does not exist.

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

```alloy
otelcol.processor.transform "default" {
  error_mode = "ignore"

  trace_statements {
    context = "span"
    statements = [
      // Accessing a map with a key that does not exist will return nil.
      `set(attributes["test"], "pass") where attributes["test"] == nil`,
    ]
  }

  output {
    metrics = [otelcol.exporter.otlp.default.input]
    logs    = [otelcol.exporter.otlp.default.input]
    traces  = [otelcol.exporter.otlp.default.input]
  }
}
```

Each statement is enclosed in backticks instead of quotation marks. This constitutes a [raw string](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#raw-strings), and lets us avoid the need to escape each `"` with a `\"` inside a [normal](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#strings) River string.

### Rename a resource attribute

The are two ways to rename an attribute key. One way is to set a new attribute and delete the old one:

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

```alloy
otelcol.processor.transform "default" {
  error_mode = "ignore"

  trace_statements {
    context = "resource"
    statements = [
      `set(attributes["namespace"], attributes["k8s.namespace.name"])`,
      `delete_key(attributes, "k8s.namespace.name")`,
    ]
  }

  output {
    metrics = [otelcol.exporter.otlp.default.input]
    logs    = [otelcol.exporter.otlp.default.input]
    traces  = [otelcol.exporter.otlp.default.input]
  }
}
```

Another way is to update the key using regular expressions:

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

```alloy
otelcol.processor.transform "default" {
  error_mode = "ignore"

  trace_statements {
    context = "resource"
    statements = [
     `replace_all_patterns(attributes, "key", "k8s\\.namespace\\.name", "namespace")`,
    ]
  }

  output {
    metrics = [otelcol.exporter.otlp.default.input]
    logs    = [otelcol.exporter.otlp.default.input]
    traces  = [otelcol.exporter.otlp.default.input]
  }
}
```

Each statement is enclosed in backticks instead of quotation marks. This constitutes a [raw string](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#raw-strings), and lets us avoid the need to escape each `"` with a `\"`, and each `\` with a `\\` inside a [normal](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#strings) River string.

### Create an attribute from the contents of a log body

This example sets the attribute `body` to the value of the log body:

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

```alloy
otelcol.processor.transform "default" {
  error_mode = "ignore"

  log_statements {
    context = "log"
    statements = [
      `set(attributes["body"], body)`,
    ]
  }

  output {
    metrics = [otelcol.exporter.otlp.default.input]
    logs    = [otelcol.exporter.otlp.default.input]
    traces  = [otelcol.exporter.otlp.default.input]
  }
}
```

Each statement is enclosed in backticks instead of quotation marks. This constitutes a [raw string](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#raw-strings), and lets us avoid the need to escape each `"` with a `\"` inside a [normal](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#strings) River string.

### Combine two attributes

This example sets the attribute `test` to the value of attributes `service.name` and `service.version` combined.

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

```alloy
otelcol.processor.transform "default" {
  error_mode = "ignore"

  trace_statements {
    context = "resource"
    statements = [
      // The Concat function combines any number of strings, separated by a delimiter.
      `set(attributes["test"], Concat([attributes["foo"], attributes["bar"]], " "))`,
    ]
  }

  output {
    metrics = [otelcol.exporter.otlp.default.input]
    logs    = [otelcol.exporter.otlp.default.input]
    traces  = [otelcol.exporter.otlp.default.input]
  }
}
```

Each statement is enclosed in backticks instead of quotation marks. This constitutes a [raw string](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#raw-strings), and lets us avoid the need to escape each `"` with a `\"` inside a [normal](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#strings) River string.

### Parsing JSON logs

Given the following JSON body:

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

```json
{
  "name": "log",
  "attr1": "example value 1",
  "attr2": "example value 2",
  "nested": {
    "attr3": "example value 3"
  }
}
```

You can add specific fields as attributes on the log:

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

```alloy
otelcol.processor.transform "default" {
  error_mode = "ignore"

  log_statements {
    context = "log"

    statements = [
      // Parse body as JSON and merge the resulting map with the cache map, ignoring non-json bodies.
      // cache is a field exposed by OTTL that is a temporary storage place for complex operations.
      `merge_maps(cache, ParseJSON(body), "upsert") where IsMatch(body, "^\\{")`,

      // Set attributes using the values merged into cache.
      // If the attribute doesn't exist in cache then nothing happens.
      `set(attributes["attr1"], cache["attr1"])`,
      `set(attributes["attr2"], cache["attr2"])`,

      // To access nested maps you can chain index ([]) operations.
      // If nested or attr3 do no exist in cache then nothing happens.
      `set(attributes["nested.attr3"], cache["nested"]["attr3"])`,
    ]
  }

  output {
    metrics = [otelcol.exporter.otlp.default.input]
    logs    = [otelcol.exporter.otlp.default.input]
    traces  = [otelcol.exporter.otlp.default.input]
  }
}
```

Each statement is enclosed in backticks instead of quotation marks. This constitutes a [raw string](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#raw-strings), and lets us avoid the need to escape each `"` with a `\"`, and each `\` with a `\\` inside a [normal](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#strings) River string.

### Various transformations of attributes and status codes

The example takes advantage of context efficiency by grouping transformations with the context which it intends to transform.

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

```alloy
otelcol.receiver.otlp "default" {
  http {}
  grpc {}

  output {
    metrics = [otelcol.processor.transform.default.input]
    logs    = [otelcol.processor.transform.default.input]
    traces  = [otelcol.processor.transform.default.input]
  }
}

otelcol.processor.transform "default" {
  error_mode = "ignore"

  trace_statements {
    context = "resource"
    statements = [
      `keep_keys(attributes, ["service.name", "service.namespace", "cloud.region", "process.command_line"])`,
      `replace_pattern(attributes["process.command_line"], "password\\=[^\\s]*(\\s?)", "password=***")`,
      `limit(attributes, 100, [])`,
      `truncate_all(attributes, 4096)`,
    ]
  }

  trace_statements {
    context = "span"
    statements = [
      `set(status.code, 1) where attributes["http.path"] == "/health"`,
      `set(name, attributes["http.route"])`,
      `replace_match(attributes["http.target"], "/user/*/list/*", "/user/{userId}/list/{listId}")`,
      `limit(attributes, 100, [])`,
      `truncate_all(attributes, 4096)`,
    ]
  }

  metric_statements {

Each statement is enclosed in backticks instead of quotation marks. This constitutes a [raw string](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#raw-strings), and lets us avoid the need to escape each `"` with a `\"`, and each `\` with a `\\` inside a [normal](/docs/agent/v0.43/flow/concepts/config-language/expressions/types_and_values/#strings) River string.
