# Agent Check: ClickHouse

## Overview

This check monitors [ClickHouse][1] through the Datadog Agent.

## Setup

Follow the instructions below to install and configure this check for an Agent running on a host. For containerized environments, see the [Autodiscovery Integration Templates][2] for guidance on applying these instructions.

### Installation

The ClickHouse check is included in the [Datadog Agent][3] package. No additional installation is needed on your server.

### Configuration

<!-- xxx tabs xxx -->
<!-- xxx tab "Host" xxx -->

#### Host

To configure this check for an Agent running on a host:

#### Metric collection

1. To start collecting your ClickHouse performance data, edit the `clickhouse.d/conf.yaml` file in the `conf.d/` folder at the root of your Agent's configuration directory. See the [sample clickhouse.d/conf.yaml][4] for all available configuration options.

2. [Restart the Agent][5].

##### Log collection

1. Collecting logs is disabled by default in the Datadog Agent, enable it in your `datadog.yaml` file:

   ```yaml
   logs_enabled: true
   ```

2. Add the log files you are interested in to your `clickhouse.d/conf.yaml` file to start collecting your ClickHouse logs:

   ```yaml
     logs:
       - type: file
         path: /var/log/clickhouse-server/clickhouse-server.log
         source: clickhouse
         service: "<SERVICE_NAME>"
   ```

    Change the `path` and `service` parameter values and configure them for your environment. See the [sample clickhouse.d/conf.yaml][4] for all available configuration options.

3. [Restart the Agent][5].

<!-- xxz tab xxx -->
<!-- xxx tab "Containerized" xxx -->
