ClickHouse Monitoring

Use the ClickHouse plugin to monitor the read and write performance for a select time period, the rate of Insert and Select queries per ClickHouse instance, the number of rows written per query, and more.

Being an open source database management system, ClickHouse is used for large-scale data analysis jobs, running around 100 queries per second on a single ClickHouse instance. Monitoring ClickHouse queries is critical to make them suitable for maximum performance and ensure a minimum load on your system.

Performance Monitoring Metrics

We provide separate ClickHouse plugin extensions to monitor their events, async metrics, and system metrics. Refer our Gihub repository to view the complete list of performance metrics provided for each of these plugins.


  • Ensure the Clickhouse Python Driver is installed. To install the driver, execute the following command:
    pip install clickhouse-driver
  • Our Linux server monitoring agent should be installed where the ClickHouse database is running.
  • While adding a plugin, the plugin name and its folder name should be identical.

Plugin Installation

Supported Platform: Linux

  • Download and install the latest version of the Site24x7 Linux agent in the server where you plan to run the plugin. If it is installed successfully, you will see a Linux server monitor in the Site24x7 Control Panel. This confirms that the agent is able to communicate with our Data Center.
  • Download the plugins from our GitHub repository For example, to monitor the system metrics, download the plugin
  • Provide details of hostname, port, database user and password to match your configuration.
  • Create a folder with the plugin name, under the Site24x7 Linux agent plugin directory '/opt/site24x7/monagent/plugins/' and place the python file under '/opt/site24x7/monagent/plugins/<plugin name>/'
    For example, if you are using the plugin to monitor system metrics, create a folder with the name 'clickhouse_system_metrics', under the Site24x7 Linux agent plugin directory '/opt/site24x7/monagent/plugins/' and place the '' under '/opt/site24x7/monagent/plugins/clickhouse_system_metrics/'

The agent will automatically execute the plugin within five minutes and send performance data to the Site24x7 Data Center.


Manually execute the plugin script using the following command and verify its output. For example, if you are using the 'clickhouse_system_metrics' plugin,
