nrpe-server
nrpe-server provides an implementation of the NRPE (Nagios Remote Plugin Executor) server side, enabling a monitoring system to execute predefined plugin checks on remote hosts over the network.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
NRPE-style systems inherently increase risk because they facilitate remote execution. Security depends on strict allowlisting of commands, limiting who can connect (network ACLs/firewalls), and using strong authentication/encryption if supported. No specific configuration or dependency/security details were provided here to confirm TLS/auth behavior.
⚡ Reliability
Best When
You have a Nagios-style monitoring workflow and can safely restrict NRPE to a small set of approved commands on remote hosts.
Avoid When
You cannot properly lock down network access, authentication, and command allowlists for remote execution.
Use Cases
- • Nagios/Nagios-compatible monitoring where checks must run on remote machines
- • Centralized monitoring of CPU/disk/memory/services via remote plugin execution
- • Legacy NRPE-based monitoring deployments that still require remote command execution
Not For
- • Running arbitrary user-supplied commands (NRPE should be restricted to configured commands)
- • Modern service APIs or app-to-app communication
- • Environments that cannot accept any remote command execution semantics
Interface
Authentication
NRPE deployments typically rely on network-level controls and/or TLS + authentication mechanisms, but no interface details were provided here to assess the exact auth method used by this package.
Pricing
Open-source infrastructure component; no pricing information provided.
Agent Metadata
Known Gotchas
- ⚠ Remote command execution: an agent retrying failed calls may rerun checks/commands
- ⚠ Operations depend on an external monitoring orchestrator configuration (allowed commands, host ACLs, plugin behavior)
- ⚠ Network timeouts and plugin runtime can affect reliability; without retry guidance, agents may need custom handling
