# System requirements

This document contains monq server architecture and its system requirements. Please read this document before proceeding to install the system.

# Resources allocation

* Check on the amount of memory is performed at the installation stage, ``16*1024'' megabytes of memory must be available.

Product name CPU, Cores RAM, GB HDD, GB Description
monq Free 8 28 100 Server for deploying infrastructure software and monq modules
monq Free Lite 8 28 100 Server for deploying infrastructure software and monq modules

⚠️ System disk sizes must be at least as indicated in the table. When partitioning, all disk space is mounted to the root «/» without division into partitions. File system – xfs.

# Storage system requirements

Server name Data Read / Write, iops (Highload) Intensity of use Notes
d-head DBMS: postgresql, arangodb, clickhouse
Storage: nfs, docker registry

# Generic network connectivity

Minimum required:

  • allowed access to 22/tcp port of all servers;
  • allowed access to 80,443/tcp port of server.

# Additionally

When deploying an instance of monq you will also need:

  • Domain name to access the Web interface of your monq platform. It is a prerequisite for issuing a license.
  • SSL certificate for the selected domain name, signed by a trusted CA, you can use Let's Encrypt (opens new window). Installation without SSL is allowed, followed by import of a self-signed certificate for the selected domain name. If there is no certificate, it will be created during the installation process. The system supports installation without SSL, but in this case, operability is not guaranteed.
