NRPE Daemon Nagios | An Introduction

by | Jul 18, 2023

NRPE daemon allows the Nagios monitoring system to execute checks on remote hosts. At Bobcares, with our Server Management Service, we can handle your Nagios issues.

NRPE Daemon In Nagios

A daemon called NRPE (Nagios Remote Plugin Executor) enables the Nagios monitoring system to do checks on distant hosts. It makes it possible for Nagios to keep an eye on a number of distant systems’ characteristics, such as their hardware health, system performance, service availability, and more.

The NRPE daemon runs the remote hosts we want to monitor, which serves as a link between Nagios and any plugins on those servers. A remote host gets a monitoring request from Nagios, and NRPE processes the request locally by launching the relevant plugin. After then, Nagios receives the results for processing and reporting.

Checking disk space, CPU, memory, ongoing processes, and other system-specific metrics are just a few of the monitoring chores that NRPE makes easier because the Nagios server can’t do that directly. It offers a quick and secure solution to gather data from distant hosts and organize the monitoring data in the Nagios system.

How To Set Up NRPE Daemon In Nagios?

Installing the NRPE daemon on the remote systems and configuring it to permit connection with the Nagios server are the normal steps in setting up NRPE. Specifically describing the checks we want to run remotely, setting up access limits to ensure a safe connection, and designating the plugins for each check are all necessary steps in this process.

Overall, NRPE is essential in enabling Nagios monitoring capabilities to remote systems, providing thorough monitoring and proactive control of the IT infrastructure.

There are two pieces to this addon:

1. nrpe: The check_nrpe plugin on the Nagios host sends command execution requests to this application, which runs in the background on the remote host. It will run the command line corresponding with the command name it got upon receiving a plugin request from an approved host. Then sends the program output and returns the code back to the check_nrpe plugin.

2. check_nrpe: The NRPE process on distant hosts is contacted via this plugin, which is run on the Nagios host. The plugin waits for the NRPE process to run the plugin and deliver the result before requesting that it be executed on the remote host. The plugin then applies its own output and return code to the output and return code from the remote host’s plugin execution.

Conclusion

The NRPE daemon acts as a bridge between Nagios and remote hosts, enabling the collection of real-time information and executing commands on the monitored systems, making it a crucial component for comprehensive network monitoring with Nagios.
