Agent-based and agentless monitoring are the two main approaches network monitoring tools use to capture and report data from network devices. As the names suggest, the difference between the two is pretty simple: someone has to install extra software(the agent) for agent-based monitoring to work. But, that doesn’t explain why an IT team or an MSP would choose agent-based or agentless monitoring.

Healthcare IT is simultaneously one of the most complex and sensitive networking systems there are. Aside from the wealth of confidential data they process and store, these networks must be highly available to support life-saving procedures and diagnostics programs. This makes proactive healthcare network monitoring—staying ahead of little issues before they become emergencies—an absolute necessity.

Network redundancy is process of providing multiple paths for traffic, so that data can keep flowing even in the event of a failure. Put simply: more redundancy equals more reliability. It also helps with distributed site management. The idea is that if one device fails, another can automatically take over. By adding a little bit of complexity, we reduce the probability that a failure will take the network down. But complexity is also an enemy to reliability.

Regex—short for regular expressions—is a way to describe a search pattern. They can be used to find a text pattern or string (character sequence) within a larger body of text, such as a sentence or paragraph, but even entire documents and databases. They can be used to quickly find specific text in a text document like a configuration file for a network device. Need to know what IP addresses a device has? What VLANs are on a switch? What devices are using a deprecated DNS server?

Simple Network Management Protocol (SNMP) is a way for different devices on a network to share information with one another. It allows devices to communicate even if the devices are different hardware and run different software. And despite any rumors you may hear, it’s not going anywhere anytime soon.

Buying the right network devices is an essential part of network design, and can have an impact throughout the network lifecycle. Get it right, and your network is high-performing, easy to troubleshoot, and reliable. Get it wrong, and downtime, complexity, and costs add up fast. A network device buyer’s guide would probably be really helpful. So we made you one.

Configuration management is one of those network management topics people often neglect. It’s not very exciting—but it’s incredibly important. Administrators rely on network configuration management in a variety of circumstances. Let’s discuss what network configuration is, delve further into the importance of network configuration, and explore the benefits of configuration management.

Hostile work environments are a real problem in tech and can be a significant driver of IT job stress. This is particularly true for IT helpdesk and support roles. Helpdesk agents often complain of burnout and frustration related to how end-users treat them. IT service roles will never be “stress-free”. The nature of break-fix work for critical systems inherently comes with the job.

In the business world, information technology (IT) is everything. Without it, companies would struggle to keep track of their data and operations. However, managing all of a company’s IT assets can be a daunting task. This is where IT asset management (ITAM) comes in.

VPNs: not just sponsors of YouTube tech videos! If you think of Virtual Private Networks (VPNs) as data privacy tools or a way to access geographically restricted content, then the idea they’re dying out probably seems far-fetched. But if we’re talking about internet-based VPNs, the kind that enables access to corporate networks, there’s been plenty of prognostication that the last days of VPN may be upon us.
