+
+# otelcol.exporter.kafka
+
+`otelcol.exporter.kafka` accepts logs, metrics, and traces telemetry data from 
+other `otelcol` components and sends it to Kafka.
+
+> **NOTE**: `otelcol.exporter.kafka` is a wrapper over the upstream
+> OpenTelemetry Collector `kafka` exporter from the `otelcol-contrib`
+> distribution. Bug reports or feature requests will be redirected to the
+> upstream repository, if necessary.
+
+Multiple `otelcol.exporter.kafka` components can be specified by giving them
+different labels.
+
+## Usage
+
+```alloy
+otelcol.exporter.kafka "LABEL" {
+  protocol_version = "PROTOCOL_VERSION"
+}
+```
+
+## Arguments
+
+The following arguments are supported:
+
+Name                                       | Type            | Description                                                                         | Default              | Required
+------------------------------------------ | --------------- | ----------------------------------------------------------------------------------- | -------------------- | --------
+`protocol_version`                         | `string`        | Kafka protocol version to use.                                                      |                      | yes
+`brokers`                                  | `list(string)`  | Kafka brokers to connect to.                                                        | `["localhost:9092"]` | no
+`topic`                                    | `string`        | Kafka topic to read from.                                                           |  _See below_         | no
+`topic_from_attribute`                     | `string`        | A resource attribute whose value should be used as the message's topic.             |  `""`                | no
+`encoding`                                 | `string`        | Encoding of payload read from Kafka.                                                | `"otlp_proto"`       | no
+`client_id`                                | `string`        | Consumer client ID to use. The ID will be used for all produce requests.            | `"sarama"`           | no
+`timeout`                                  | `duration`      | The timeout for every attempt to send data to the backend.                          | `"5s"`               | no
+`resolve_canonical_bootstrap_servers_only` | `bool`          | Whether to resolve then reverse-lookup broker IPs during startup.                   | `"false"`            | no
+`partition_traces_by_id`                   | `bool`          | Whether to include the trace ID as the message key in trace messages sent to Kafka. | `"false"`            | no
+`partition_metrics_by_resource_attributes` | `bool`          | Whether to include the hash of sorted resource attributes as the message partitioning key in metric messages sent to Kafka. | `"false"`            | no
+
+If `topic` is not set, different topics will be used for different telemetry signals:
+
+* Metrics will be received from an `otlp_metrics` topic.
+* Traces will be received from an `otlp_spans` topic.
+* Logs will be received from an `otlp_logs` topic.
+
+If `topic` is set to a specific value, then only the signal type that corresponds to the data stored in the topic must be set in the output block.
+For example, if `topic` is set to `"my_telemetry"`, then the `"my_telemetry"` topic can only contain either metrics, logs, or traces. 
+If it contains only metrics, then `otelcol.exporter.kafka` should be configured to process only metrics.
+
+When `topic_from_attribute` is set, it will take precedence over `topic`.
+
+The `encoding` argument determines how to encode messages sent to Kafka.
+`encoding` must be one of the following strings:
+* Encodings which work for traces, logs, and metrics:
+  * `"otlp_proto"`: Encode messages as OTLP protobuf. 
+  * `"otlp_json"`: Encode messages as OTLP JSON.
+* Encodings which work only for traces:
+  * `"jaeger_proto"`: The payload is serialized to a single Jaeger proto `Span`, and keyed by TraceID.
+  * `"jaeger_json"`: The payload is serialized to a single Jaeger JSON Span using `jsonpb`, and keyed by TraceID.
+  * `"zipkin_proto"`: The payload is serialized to Zipkin v2 proto Span.
+  * `"zipkin_json"`: The payload is serialized to Zipkin v2 JSON Span.
+* Encodings which work only for logs:
+  * `"raw"`: If the log record body is a byte array, it is sent as is. Otherwise, it is serialized to JSON. Resource and record attributes are discarded.
+
+`partition_traces_by_id` does not have any effect on Jaeger encoding exporters since Jaeger exporters include trace ID as the message key by default.
+

+
+The `plaintext` block configures `PLAIN` authentication against Kafka brokers.
+
+The following arguments are supported:
+
+Name | Type | Description | Default | Required
+---- | ---- | ----------- | ------- | --------
+`username` | `string` | Username to use for `PLAIN` authentication. | | yes
+`password` | `secret` | Password to use for `PLAIN` authentication. | | yes
+
+### sasl block
+
+The `sasl` block configures SASL authentication against Kafka brokers.
+
+The following arguments are supported:
+
+Name | Type | Description | Default | Required
+---- | ---- | ----------- | ------- | --------
+`username` | `string` | Username to use for SASL authentication. | | yes
+`password` | `secret` | Password to use for SASL authentication. | | yes
+`mechanism` | `string` | SASL mechanism to use when authenticating. | | yes
+`version` | `number` | Version of the SASL Protocol to use when authenticating. | `0` | no
+
+The `mechanism` argument can be set to one of the following strings:
+
+* `"PLAIN"`
+* `"AWS_MSK_IAM"`
+* `"SCRAM-SHA-256"`
+* `"SCRAM-SHA-512"`
+
+When `mechanism` is set to `"AWS_MSK_IAM"`, the [`aws_msk` child block][aws_msk] must also be provided.
+
+The `version` argument can be set to either `0` or `1`.
+
+### aws_msk block
+
+The `aws_msk` block configures extra parameters for SASL authentication when
+using the `AWS_MSK_IAM` mechanism.
+
+The following arguments are supported:
+
+Name | Type | Description | Default | Required
+---- | ---- | ----------- | ------- | --------
+`region` | `string` | AWS region the MSK cluster is based in. | | yes
+`broker_addr` | `string` | MSK address to connect to for authentication. | | yes

+brokers. If the `tls` block isn't provided, TLS won't be used for
+communication.
+
+{{< docs/shared lookup="reference/components/otelcol-tls-client-block.md" source="alloy" version="<ALLOY_VERSION>" >}}
+
+### kerberos block
+
+The `kerberos` block configures Kerberos authentication against the Kafka
+broker.
+
+The following arguments are supported:
+
+Name | Type | Description | Default | Required
+---- | ---- | ----------- | ------- | --------
+`service_name` | `string` | Kerberos service name. | | no
+`realm` | `string` | Kerberos realm. | | no
+`use_keytab` | `string` | Enables using keytab instead of password. | | no
+`username` | `string` | Kerberos username to authenticate as. | | yes
+`password` | `secret` | Kerberos password to authenticate with. | | no
+`config_file` | `string` | Path to Kerberos location (for example, `/etc/krb5.conf`). | | no
+`keytab_file` | `string` | Path to keytab file (for example, `/etc/security/kafka.keytab`). | | no
+
+When `use_keytab` is `false`, the `password` argument is required. When
+`use_keytab` is `true`, the file pointed to by the `keytab_file` argument is
+used for authentication instead. At most one of `password` or `keytab_file`
+must be provided.
+
+### metadata block
+
+The `metadata` block configures how to retrieve and store metadata from the

+---- | ---- | ----------- | ------- | --------
+`include_all_topics` | `bool` | When true, maintains metadata for all topics. | `true` | no
+
+If the `include_all_topics` argument is `true`, `otelcol.exporter.kafka`
+maintains a full set of metadata for all topics rather than the minimal set
+that has been necessary so far. Including the full set of metadata is more
+convenient for users but can consume a substantial amount of memory if you have
+many topics and partitions.
+
+Retrieving metadata may fail if the Kafka broker is starting up at the same
+time as the `otelcol.exporter.kafka` component. The [`retry` child
+block][retry] can be provided to customize retry behavior.
+
+### retry block
+
+The `retry` block configures how to retry retrieving metadata when retrieval
+fails.
+
+The following arguments are supported:

+
+{{< docs/shared lookup="reference/components/otelcol-retry-block.md" source="alloy" version="<ALLOY_VERSION>" >}}
+
+### queue block
+
+The `queue` block configures an in-memory buffer of batches before data is sent to the gRPC server.
+

+## Exported fields
+
+The following fields are exported and can be referenced by other components:
+
+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.exporter.kafka` is only reported as unhealthy if given an invalid
+configuration.
+
+## Debug information
+
+`otelcol.exporter.kafka` does not expose any component-specific debug
+information.
+
+## Example
+
+This example forwards telemetry data through a batch processor before finally sending it to Kafka:
+
+```alloy
+otelcol.receiver.otlp "default" {
+  http {}
+  grpc {}
+
+  output {
+    metrics = [otelcol.processor.batch.default.input]
+    logs    = [otelcol.processor.batch.default.input]
+    traces  = [otelcol.processor.batch.default.input]
+  }
+}
+
+otelcol.processor.batch "default" {
+  output {
+    metrics = [otelcol.exporter.kafka.default.input]
+    logs    = [otelcol.exporter.kafka.default.input]
+    traces  = [otelcol.exporter.kafka.default.input]
+  }
+}
+
+otelcol.exporter.kafka "default" {

+The `sasl` block configures SASL authentication against Kafka brokers.
+
+The following arguments are supported:
+
+Name | Type | Description | Default | Required
+---- | ---- | ----------- | ------- | --------
+`username` | `string` | Username to use for SASL authentication. | | yes
+`password` | `secret` | Password to use for SASL authentication. | | yes
+`mechanism` | `string` | SASL mechanism to use when authenticating. | | yes
+`version` | `number` | Version of the SASL Protocol to use when authenticating. | `0` | no
+
+The `mechanism` argument can be set to one of the following strings:
+
+* `"PLAIN"`
+* `"AWS_MSK_IAM"`
+* `"SCRAM-SHA-256"`
+* `"SCRAM-SHA-512"`
+
+When `mechanism` is set to `"AWS_MSK_IAM"`, the `aws_msk` child block must also be provided.
+
+The `version` argument can be set to either `0` or `1`.

+description: Shared content, otelcol kafka metadata

+
+The `metadata` block configures how to retrieve and store metadata from the
+Kafka broker.
+
+The following arguments are supported:
+
+Name | Type | Description | Default | Required
+---- | ---- | ----------- | ------- | --------
+`include_all_topics` | `bool` | When true, maintains metadata for all topics. | `true` | no
+
+If the `include_all_topics` argument is `true`, 
+a full set of metadata for all topics is maintained rather than the minimal set
+that has been necessary so far. Including the full set of metadata is more
+convenient for users but can consume a substantial amount of memory if you have
+many topics and partitions.
+
+Retrieving metadata may fail if the Kafka broker is starting up at the same
+time as the Alloy component. The `retry` child block can be provided to customize retry behavior.
