Nagios: Identifying and Resolving Network Blackouts

CIO VendorEthan Galstad, Founder & CEO
It all began in 1996, when Ethan Galstad started creating a simple MS-DOS application designed to ping Novell Netware servers. “A quick investigation revealed that using commercial network monitoring software packages would have been too expensive to offer services at reasonable rates,” reckons Galstad, Founder and CEO of Nagios. As a consequence, Nagios was designed to make use of and re-use external applications, rather than be an all-inclusive application that did everything itself. “This meant admins could use tools they were already familiar with to extend Nagios' capabilities and integrate it with their particular environment,” asserts Galstad. The Saint Paul, MN based Nagios monitors organizations complete IT infrastructure to ensure that services, systems, applications, and business processes are all performing ideally. The firm gives handy information in the IT monitoring space—hosting regular alerts of network blackouts to the technical team, allowing them to begin remediation processes before the situation turns haywire, affecting the end-users, business processes, or customers.

Nagios XI—an enterprise server and network monitoring software from Nagios monitors of all the mission-critical infrastructure components including operating systems, applications, systems metrics, network protocols, and network infrastructure. The software enables users to have a complete view of their IT operations network and business processes with the help of useful dashboards. With the use of the powerful Nagios Core 4 monitoring engine Nagios XI sends alerts to business stakeholders, IT staff, and end-users via mobile text messages, or email providing the users with outage details to resolve the network issues instantaneously.

The firm’s Nagios Log Server, a powerful enterprise-class management log monitoring, and analysis application enables organizations to easily examine, inquire, and analyze the timely logs from all machine-generated log data. Based on custom specifications, this Log Server provides resourceful insights into all the data on user’s network infrastructure all in a consolidated place.

Adding momentum to Nagios XI and Nagios Log Server, Nagios Network Analyzer—a commercial-grade network flow data analysis solution offers organizations a complete view into the network traffic areas. It allows the users to be practical in identifying abnormal behavior and recognizing security threats before they impinge on critical business processes.

Once, Nagios was approached by Watch Communications, a broadband solution provider that wireless TV, Internet, and phone service via microwave fixed wireless to residential and business customers. Having a large number of valuable equipments to their business model, the client was in need of a solution that could furnish the gist of all the crucial information about their equipment, precisely not just identifying whether the equipment is up or down—but also giving handy information on signal strengths, connection counts, dynamic routing peer counts, battery status, and temperature. In addition, they wanted custom alerting and response solution, beyond the standard email alerts offered by other monitoring solutions. Nagios assisted the client with a network of open-source customizable plugins and customized alerting solutions enabling them to quickly identify incidents from power issues to connection issues to environment problems. The client then built custom SMS response scripts by using Nagios which allowed them to acknowledge and handle alerts remotely.

Being an industry-standard in IT infrastructure monitoring, Nagios has always been a company synonymous with innovation and customer satisfaction. The firm ushers in a new era of growth by improving customer experience through their pragmatic technology solutions to foster new product innovation, and expand its operations steadily to harness the customer requisites by augmenting their services according to the needs of the customers.
