The Best Hardware Monitoring Tools

1. NinjaOne RMM (FREE TRIAL)

NinjaOne RMM

NinjaOne RMM is a remote monitoring and management package that is based in the cloud. The system accesses each monitored site through the installation of a data collector on one of the hosts connected to that network.

Key Features:

  • Network device and endpoint discovery
  • Hardware documentation in an inventory
  • Uses SNMP for automated monitoring
  • Software inventory
  • Patch management

The RMM exploits the Simple Network Management Protocol (SNMP). This system requires an SNMP Manager and the NinjaOne data collector fulfills this role. The SNMP Manager broadcasts a status report request and every device connected to the network responds.

Every network device is shipped with an SNMP agent installed on it and there is also an SNMP agent embedded in every operating system. So, this process is able to discover, document, and monitor every piece of hardware that is connected to your network. SNMP also provides a mechanism for an emergency warning if the device agent discovers a problem. NinjaOne RMM converts this notification into an alert.


  • Can monitor any site anywhere in the world
  • A cloud-based console that is accessed through any standard Web browser
  • Includes a Help Desk ticketing system
  • Multi-tenant architecture for managed service providers
  • Constantly updated activity reports and device statuses


  • No on-premises hosting option

NinjaOne levies a price per device. However, the company doesn’t publish that rate and you have to negotiate a price for your requirements. You can examine the NinjaOne RMM by accessing a 14-day free trial.


NinjaOne RMM is our top pick for a hardware monitoring tool because it is able to monitor entire sites from across the internet. This package will discover and document all hardware on a site and then continuously monitor the statuses of every network device, workstation, and server. The package includes an alerting mechanism, which will notify your technicians if a problem is discovered. Alerts can be channeled through a Help Desk ticketing system, which is included in the package. The support team accessed the NinjaOne dashboard over the Web and the system allows the creation of sub-accounts, making it ideal for use by managed service providers. As well as monitoring hardware, this package provides services for managing software. This division of utilities includes a patch manager.
