Before You Begin

Security Considerations

To ensure that your NGINX Management Suite deployment remains secure, follow the recommendations in this section:

Install NGINX Management Suite and its modules on a dedicated machine (bare metal, container, cloud, or VM).
Make sure that no other services are running on the same machine.
Make sure that the machine is not accessible from the Internet.
Make sure that the machine is behind a firewall.

Installation Prerequisites

Important:
Before you can install this module, you need to have NGINX and ClickHouse installed on your system. Additionally, you will need to add the NGINX Management Suite repository. The Prerequisites topic has detailed instructions on how to fulfill these requirements.
