See also Installation Prerequisites.

Operating System and Software Requirements

For Linux deployments, 64-bit Linux-based OS is required. The following table shows the Linux distributions supported along with the corresponding minimum supported version. Composer Server also uses Java, PostgreSQL, and Spark. Ensure that the appropriate version of these tools are used in the deployment of Composer in your operating environment.

Important CentOS 6 Information

CentOS 6 is no longer supported and the special installation Bootstrap procedure (bootstrap-zoomdata-centos6.run) is no longer provided with this product. CentOS 6 is no longer supported by Red Hat Linux (RHEL). Use CentOS 7 or 8 instead.

Important Ubuntu Information

Ubuntu users who have Composer or Zoomdata versions earlier than 5.8 installed must first remove the legacy repository before upgrading Composer 5.8 or later. Use this command:

sudo rm -f /etc/apt/sources.list.d/saltstack.list

Hardware Requirements

For RPM and Ubuntu installations, the following server specifications are recommended:

• 64 GB RAM (minimum is 16 GB)
• 500 GB disk space
• 16 cores

See also Sizing Guidelines.

Metadata Repository

Composer uses a packaged PostgreSQL v12 database instance to store its metadata and strongly recommends using this instance due to the specific configuration and version employed. If you would like to use another PostgreSQL instance, contact Technical Support for further guidance.

Network Requirements

Ports

The following table lists the ports you must consider when installing or upgrading Logi Composer.

Time Synchronization

Composer recommends installing the Network Time Protocol daemon (NTPD) to allow for time synchronization of networked servers to Coordinated Universal Time (UTC), if not already available in your network. See Using the Network Time Protocol to Synchronize Time for guidance.

Supported Browsers

Due to the WebSocket technology that Composer uses, you need to use one of the following browsers to access the client application.
