What is IT Operations Management

The world of IT networking has countless acronyms for every component, metric, technology, function, and so on. ITOM, or IT operations management, is a function that encapsulates the administration of all network infrastructure components within an organization. ITOM is a critical function that can directly determine the fortunes of the company. It is for the same reason that we should clearly understand what it stands for, why it's needed, and what its benefits are. Let's dive in.

How to Achieve Full Stack Observability in Highly Distributed Environments Webinar

Your modern IT infrastructure has become an increasingly complicated mix of on-premises, public and private cloud applications, devices and environments. Forward-thinking organizations are addressing this complexity by transitioning to a proactive “observability” approach for infrastructure management. This methodology produces and then applies actionable data to optimize and secure the entire network.

Exploring Your Network Data With Kentik Data Explorer

A cornerstone of network observability is the ability to ask any question of your network. That means having an unbound capacity to explore the tremendous amount and variety of network telemetry you collect. It means seeing trends and patterns from a macro level, but it also means getting very granular to pursue any line of analysis of your data. Collecting information from flow records, SNMP, streaming telemetry, BGP, eBPF, and so on is indeed very important.

Learn about CWDM vs DWDM

Meeting bandwidth capacity needs of customers is a crucial business objective for today’s providers. While both coarse wavelength-division multiplexing (CWDM) and dense wavelength-division multiplexing (DWDM) are modern forms of wavelength-division multiplexing (WDM) that effectively solve those increasing bandwidth needs by upgrading the utilization of new and existing fiber, they are each designed to tackle different network challenges.

The 2023 Network IT Management Report Part 3: Extending Your Reach

This is the third in a four-part series focusing on the findings from our 2023 annual Field Report for IT Management. We surveyed 4500 IT professionals from internal IT teams and MSPs across North America to gauge where their organizations are heading from a network management perspective. In part three, we’ll discuss how organizations are thinking about extending the reach of their visibility and control over their networks with Wi-Fi and SaaS management.

The Ultimate Guide to SNMP

Simple Network Management Protocol (SNMP) is a basic network protocol designed to collect and report data from network devices connected to IP networks — even if the devices are different hardware and run different software. Most modems, routers, switches, servers, workstations, and printers will support SNMP communication. SNMP messages are transported via UDP on port 161.
