About:
NRPE (Nagios Remote Plugin Executor) is a critical component of the Nagios monitoring system, designed to execute plugins on remote Linux/Unix hosts. It allows a central Nagios server to query remote machines for service metrics like disk usage, load, and process status without requiring a full Nagios installation on each endpoint. This enables scalable, distributed monitoring of infrastructure health from a single location.
Key Features:
  • Secure communication between Nagios server and remote agents
  • Lightweight agent that runs standard Nagios plugins on remote hosts
  • Supports both active (server-initiated) and passive (agent-initiated) checks
  • Simple configuration using standard Nagios plugin syntax
Use Cases:
  • Monitoring server resources (CPU, memory, disk) on remote Linux/Unix systems
  • Checking service availability and application health metrics from a central Nagios instance
  • Distributed monitoring of network infrastructure behind firewalls
Alternatives:
  • NRPE – NRPE is the legacy standard but requires maintaining agent software on each host
  • SSH-based checks – Simpler setup using existing SSH but less efficient and requires managing SSH keys
  • Agentless monitoring – Uses SNMP/WMI but provides less detailed application-level metrics than NRPE plugins
