Monitoring

In this post, we’ll discuss how WhatsUp Gold (WUG) can help you monitor VoIP performance, and demonstrate how to set up performance monitoring for VoIP devices.

The Simple Network Management Protocol (SNMP) sure does pack a punch for something with “Simple” in its name.

In this article, you’ll learn what packet sniffing is as well as practical use cases you, as a network admin, can expect to run into.

As IT pros already know, when we speak of ports, we mean the 16-bit virtual ports used when interconnecting systems i.e. during communication over protocols such as TCP or UDP and not physical connections on the system such as USB, HDMI etc. See the OSI model and list of port numbers and their assigned function if not an IT pro. Port 80 is commonly used for HTTP activity, for example, and many applications communicate using assigned default ports.

Two key tools that network admins use for monitoring are NetFlow and sFlow. In this article, we'll compare both, and see if they can work together.

Many organizations that rely on Amazon Web Services (AWS) aren't doing the best job tracking their AWS resource usage and spending– they just pay the monthly bill from Amazon. Unless that bill significantly increases, they have no incentive to determine if they’re really using all those resources or if they’re being accurately billed. But they should be— many companies pay an average of 36% more for cloud services than they need to, according to one report.

Providing fast access to applications and data while protecting digital assets are the two biggest challenges faced by network administrators. Performance and security represent the two-pronged mission that administrators find themselves facing every day.

When troubleshooting problems or investigating potential security breaches, the Windows event log is a great place to start. Windows provides an extensive list of various event logs grouped by a provider with a sometimes staggering number of events recorded within. With all of these events being recorded, it's hard to figure out what's going on. One way to search event logs across not one but hundreds of servers at once is with PowerShell.

Amazon Web Services (AWS) have simply become a fact of life for most IT organizations. The benefits of outsourcing networking to Amazon’s cloud are simply too obvious to ignore or to not take advantage of.

Working in a DevOps environment, agility is everything. That next release needs to get into production quickly, so even a minor network issue can hamper speed and efficiency.

WhatsUp Gold can monitor every single part of your network to give you a wealth of information on status, performance, traffic and thousands of other metrics. And now WhatsUp Gold can share that information directly with any of your systems thanks to our new REST API.

It’s been predicted for years that most computers will run in the cloud and your screen will be the only connection between you and the cloud. Does that mean the business infrastructures will matter anymore, and what does that mean for the future of network monitoring?

If you’ve ever said that or even thought it, then you know exactly how much fun taking inventory is. Or is not, rather. Every industry requires periodic asset inventory – that’s just a fact of life.

Your network is a living, breathing entity. Like a living body or an organic brain, it’s constantly moving things around and changing from moment to moment. Every single individual part is in continuous contact with and reacting to every other part. The job of your monitoring tool is to track all of this.

Company bandwidth usage has, for reasons other than expected growth, increased dramatically and continues to do so every year. Over time this usage is going to increase beyond your workforce's limitations, which poses an important challenge for IT teams.

Everyone and everything in our modern connected world uses bandwidth. The pipes are now far bigger than the old 56kbps dial-up speeds most of the world endured once upon a time, so bandwidth is usually not seen as an issue by the vast majority of network users. Well, not until there’s a problem, that is.

As a former cubicle-based drone, I can readily identify with the bandwidth problems faced by users, with slowdowns and interruptions suffered for a variety of reasons, whether it is essential backups best run after-hours, problems with new security patches or updates, failing hardware or streaming video addicts.

Simple Network Management Protocol (SNMP) is a standard set of communication rules, that is, a protocol. This protocol governs the main way for querying and monitoring the hardware and software on a computer network.

From IT to marketing, cloud computing has revolutionized the way the world does business. We now a maintenance-free to get unlimited scalability and reliability, and we’re all going to live happily ever after, right?

Monitoring bandwidth usage is a vital aspect of any network management strategy. Bandwidth monitors collect, monitor and analyze network traffic volume by end-point (user), port, interface and protocol (application). This information enables IT Admins to:
