NEMS Linux – Nagios Enterprise Monitoring Server for Raspberry Pi
Current Version: 1.2.3 (September 8, 2017)
Next Major Release: 1.3 (November 7, 2017)
NEMS is a modern pre-configured, customized and ready-to-deploy Nagios Core image designed to run on the Raspberry Pi 3 micro computer. At its core it is a lightweight Debian Stretch deployment optimized for performance, reliability and ease of use.
NEMS is free to download, deploy, and use. Its development however is supported by its community of users. Please consider contributing if you can.
Please Note: NEMS 1.2.x is my most ambitious NEMS release yet. Please consider throwing a little gift in my Tip Jar if you find NEMS saves you time or money. Thanks!

Here’s our link to buy the device you’ll need, complete with the Micro SD card, a power adapter, a good solid case, and more: shop.category5.tv
Please buy it through that link, or let me know if you need a customized link to a different model. We get a small percentage of the sale, and it helps to make it possible to offer this as a free download.
NEMS 1.2.1 Image File – 1.27 GB ZIP File (4.68 GB Uncompressed)
Released May 22, 2017. Fixes the problems with NEMS 1.2 release.
Unzip and “burn” to 8 GB+ Raspberry Pi 3 Micro SD Card (I recommend you use at least a 16 GB card so there’s plenty of room for logs, configs, data and so-on).
BitTorrent seed coming soon.
Upgrade to NEMS 1.2.3
NEMS 1.2.2 was the first ever rolling upgrade of NEMS. This means you do not need to reinstall NEMS to get the latest features. You must have NEMS 1.2.1 already installed to upgrade to NEMS 1.2.3. You can upgrade to NEMS 1.2.3 from either the NEMS 1.2.1 or 1.2.2 release.
- Type: sudo nems-upgrade
Configuring Your NEMS Server:
Browse to: http://NEMS.local/nconf (or http://IPADDRESS/nconf)
Make changes to the config as needed for your environment (eg., add a host, service, edit a setting)
I’ve added a few sample configurations in there (v1.1+) to help you get started.
Click: “Generate Nagios Config”
If there are no errors, you will have the option to Deploy the new Nagios Config.
Using Your NEMS Server:
Browse to: http://NEMS.local (or http://IPADDRESS)
The navigation should be fairly straightforward. To add hosts or configure your environment, use the built in nConf feature. To access reports, choose one of the reporting options under Reporting. To access info specific to your Pi (eg., memory usage) you’ll find those under System.
When you initialize NEMS, you will provide a password for the NEMS web interfaces. This username/password will be what you use to access most NEMS features (eg., nCONF, Nagios Core, Check_MK) however, Nagvis still uses admin:admin. Please be sure to change that when you first login to Nagvis. To login to Webmin, use the username pi and the password you entered for the pi user during nems-init.
Who Creates NEMS:
Robbie Ferguson is the host of Category5 Technology TV. He’s the kind of guy who when he figures stuff out, he likes to share it with others. That’s part of what makes his show so popular, but also what makes NEMS possible.
