+The `syslog-ng-ctl attach` command has the following parameters:
+
+- Attach mode: `logs` or `stdio`.
+
+    - Use `logs` to access the internal log messages of `syslog-ng`. For example, the following command changes the log level to `trace` and accesses the internal logs of `syslog-ng`:
+
+        ```shell
+        syslog-ng-ctl attach logs --seconds 10 --log-level trace

+
+    - Use `stdio` to display the output of the `syslog-ng` process. For example:
+
+        ```shell

+
+- Change `log-level` to the specified value:

+
+Starting with version 4.9.0, {{% param "product_name" %}} can send data to [ClickHouse databases](https://clickhouse.com/) using its [gRPC interface](https://clickhouse.com/docs/en/interfaces/grpc).
+
+## Prerequisites
+
+- A [self-hosted ClickHouse installation](https://clickhouse.com/docs/en/install).
+
+    {{% alert title="Warning" color="warning" %}}
+ClickHouse Cloud doesn't support the gRPC interface currently.
+    {{% /alert %}}
+
+- The [gRPC interface](https://clickhouse.com/docs/en/interfaces/grpc) must be enabled in your ClickHouse configuration.
+- To configure {{% param "product_name" %}}, you'll need:
+
+    - the name of an existing database and a table where you want to send your data, and
+    - the credentials (username and password) to access the database.
+
+Example configuration (sends data to the default `localhost:9100` URL):
+
+```sh
+destination {
+  clickhouse(
+    database("default")
+    table("demo_table")
+    user("your-username")
+    password("your-password")
+    schema(
+      "user_id" UInt32 => $R_MSEC,
+      "message" String => "$MSG",
+      "timestamp" DateTime => "$R_UNIXTIME",
+      "metric" Float32 => 3.14
+    )
+  );
+};
+```
+

+| -------- | -------------------------- |
+| Type:    | See the description |
+| Default: | - |
+
+*Description:* Sets the schema of the database table from a protobuf schema file.
+
+```shell
+protobuf-schema("/tmp/test.proto" => "$MESSAGE", "$PROGRAM", "$HOST", "$PID")
+```
+
+An example proto file when using the `protobuf-schema()` option:
+
+```shell
+syntax = "proto2";
+​
+message CustomRecord {
+  optional string message = 1;
+  optional string app = 2;
+  optional string host = 3;
+  optional int64 pid = 4;
+}
+```
+
+Alternatively, you can set the schema with the [`schema()`](#schema) option.

+{{% include-headless "chunk/option-destination-retries.md" %}}
+
+## schema()

+|          |                            |
+| -------- | -------------------------- |
+| Type:    | arrow list |
+| Default: |  |
+
+*Description:* Sets the schema of the database table. On the left side of the arrow, set the name of the column and its type. On the right side, set any {{% param "product_name" %}} template or macro, which gets evaluated on each log that is routed to the destination. For example:
+
+```shell
+schema(
+  "user_id" UInt32 => $R_MSEC,
+  "message" String => "$MSG",
+  "timestamp" DateTime => "$R_UNIXTIME",
+  "metric" Float32 => 3.14
+)
+```
+
+Alternatively, you can set the schema with the [`protobuf-schema()`](#protobuf-schema) option.
+
