Managing printers can be a frustrating aspect of system administration for both work and home environments. Other examples include garage door status alerting based on time of day, energy usage reports, and many other projects! If the refrigerator is open for more than a defined set of time, users can receive a text message. For example, if temperature sensors are located inside a refrigerator or freezer, Nagios XI can be configured to accept the temperature data from the Raspberry Pi and chart out compressor cycle variants and alert based on abnormal ranges. Raspberry Pi users have even more customization abilities around sensor data. Nagios XI can accept this data and report on or alert based on thresholds and sensor information. Smart home platforms such as SmartThings, Phillips Hue, Ecobee, Vera, OpenHab, Home Assistant, and many others feature various methods of getting data in and out of their ecosystems. Blanketing a house with an array of sensors and switches can be a great way to make life easier, however sometimes the devices can be an overwhelming addition to a network or lack specific reporting and alerting abilities. Smart home automation is one of the newer trends in consumer technology.

With Nagios XI and the Nagios Cross-Platform Agent (NCPA) users can grab both real-time data on key resources as well as alerting and trending information based on the hardware and software used to either stream, game, or play multimedia on.
Real-time statistics can be gathered a number of unique ways, but the ability to pull historical data can also be essential. Performance data on resource intense machines has always been a multi-directional approach. In many cases, knowing what ports or devices are generating traffic at certain times of the day can also prove to be handy when troubleshooting a high latency connection or packet loss at home. Many internet service providers have introduced data limits similar to cellular plans, so having the ability to run reports and receive notifications based on usage thresholds can dramatically reduce the chances of overages showing up on your next monthly bill. Monitoring bandwidth and Internet usage has become an important part of residential networks as the demand for live streaming, video games, and teleworking increases. Whether your home router or firewall is a large Cisco appliance, virtualized, or anywhere in between (such as a DD-WRT/OpenWRT/Tomato variant), Nagios XI can easily be configured to monitor and report on network performance by walking through the included SNMP or Switch/Router wizards. This simple design allows you to minimize cost, while addressing potential problems with the primary Nagios XI server, and ensuring that monitoring contacts are notified in case of failures.Nagios XI is an incredibly powerful enterprise tool, but the free 7 Node license can be extremely beneficial for home use! For this list, we are inspired by the ever growing community of home lab, tech enthusiasts, and system administrators who have a little network closet of their own to keep the household running well.

Nagios XI is licensed for free usage if you monitor seven nodes or less, so in this instance you don’t need to purchase a separate license. The design is quite simple – see the picture below: It is not configured to monitor all the individual infrastructure components that the primary server monitors. In other words, the offsite Nagios XI instance is configured to only monitor the primary Nagios XI server. By default, the following checks are included: Ping, Nagios XI Web Interface, Monitoring Daemons, Monitoring Jobs, Load, and I/O Wait. You can accomplish this by simply running the Nagios XI Server Monitoring Wizard against your primary Nagios XI server. The solution is to monitor the primary Nagios XI monitoring server from an offsite location to ensure it is both reachable and operating properly. Many people rely on Nagios XI for their monitoring needs, but what happens if the primary XI monitoring server goes down, crashes, loses power, or gets disconnected from the network? For example, if your border router or internet connection goes down, Nagios XI will be unable to deliver email alerts to admins.
