Remote monitoring and management (RMM) is used by managed service providers (MSPSs) to monitor and manage their clients through the use of installed “agents.”
Wikipedia
Remote monitoring and management (RMM) is the process of supervising and controlling IT systems (such as network devices, desktops, servers and mobile devices) by means of locally installed agents that can be accessed by a management service provider. Functions include the ability to:
install new or updated software remotely (including patches, updates and configuration changes)
detect new devices and automatically install the RMM agent and configure the device
observe the behavior of the managed device and software for performance and diagnostic tasks
perform alerting and provide reports and dashboards
Traditionally this function has been done on site at a company but many MSPs are performing this function remotely using integrated SaaS platforms.
