WhatsUp Gold from Ipswitch is one of the all-around best known and oldest network monitoring tools. It is old enough that many organizations have been using it for a while without questioning their choice and are only now asking themselves whether or not there’s something better out there. While the absolute value of any type of network administration tool has more to do with its relevance to your needs, we thought we’d give you a hand by posting this list of the best WhatsUp Gold alternatives for monitoring networks and systems. Our goal is to offer you reviews of some of the best tools that can be used to replace WhatsUp Gold, no matter what your reasons are for replacing it.
We’ll begin our journey by having a detailed look at WhatsUp Gold. After all, if we want to know what features to look for in replacements, we need to know what features are included in the tool. We’ll then discuss SNMP as it is the most used monitoring technology. We’ll try to explain what it is and how it works without going overly technical. Knowing how monitoring works will help you better appreciate our product reviews. With all this background behind us, we’ll tackle the core of the matter, reviewing the best network Monitoring tools we could find.
A Look At WhatsUp Gold
When WhatsUp Gold was first released, some twenty-something years ago, it was basically an up-or-down type of monitoring tool. It was based on ping and could tell you whether any host was up or down. It could also alert administrators whenever a host stopped responding. In fact, alerting was one of the tool’s best features; and it still is. Since then, the tool has since has evolved—a lot—into a full management tool with proactive monitoring of network traffic, applications, virtual environments, and device configurations. Today, WhatsUp Gold has almost everything anyone could expect from an enterprise-grade monitoring tool, all available via an intuitive GUI.
WhatsUp Gold features an auto-discovery engine that will find your devices and add them to the monitoring console. In addition to your networking equipment, it will also physical servers, virtual servers, cloud servers, and applications. The tool even has a map view which is clickable for more information on each device.
Like it always had, WhatsUp Gold boasts some excellent alerting capabilities to keep you aware of problems before users notice them. Through the tool’s Alert Center, you can opt to use some of the predefined thresholds or to set them according to your precise needs. The alerting system also allows you to create action policies that define what happens whenever a monitored parameter changes state. Back to alerts, they can be transmitted by email, SMS, Slack, or IFTTT posts. The system can also launch scripts to restart services and trigger web alarms.
WhatsUp Gold’s advanced functions will let you monitor and map everything from the edge to the cloud including devices, wireless controllers, servers, virtual machines, applications, traffic flows and configurations across Windows, LAMP and Java environments. It will let you manage networks, traffic, physical servers, virtual machines, and applications with easy-to-use and customizable maps, dashboards and alerts. Clicking on any device gives you immediate access to a wealth of related network monitoring settings and reports.
WhatsUp Gold doesn’t stop at servers, it will also monitor Windows, Linux, Apache, Java and custom applications. Its network traffic analysis capabilities help assure the performance of critical apps and services by giving you visibility into network bandwidth utilization. The software also helps with configuration management and has built-in support for HIPAA, SOX, FISMA, and PCI DSS compliance requirement as well as other regulations.
A free edition of WhatsUp Gold is available—as it always was—but it is limited to monitoring a maximum of five devices. For more devices, paid licenses are available in three levels of increasing functionality with a pricing structure based on the number of devices to be monitored. There’s also a free, full-featured trial version that you can use for a limited time.
SNMP Monitoring In A Nutshell
Despite the “S” in its name which stands for simple, SNMP, or the Simple Network Management Protocol, is actually quite complex. At its core, SNMP is a communication protocol which defines how an SNMP management system car read and write operational parameters on remote devices. The parameters are referred to as OIDs, an acronym for Object Identifiers. In the context of monitoring networking devices, two OIDs are of particular interest, the bytes out and the bytes in counters. These counters are automatically incremented by networking equipment as bytes are output or input. There is one such pair of counter per network interface.
The SNMP protocol dates back to a time when IT security was not an issue. As such, it only has minimal security. An SNMP manager connecting to an SNMP-enabled device will transmit a so-called community string with its request. If the string matches that configured in the equipment, the request will be carried out. Devices typically have two community strings, one for read-only OIDs and one for modifiable ones.
Here’s how a monitoring system such as WhatsUp Gold uses SNMP to monitor bandwidth utilization. The system periodically reads the bytes in and out counters of the networking device’s interfaces at know intervals. Typically, devices are polled every five minutes. The monitoring system stores the fetched values in some sort of database or disk file.
The rest of the process is just mathematics. The monitoring system subtracts the previous counter value from the current one to get the number of bytes transmitted or received in five minutes. It can then multiply that number by eight to get the number of bits and divide it by 300–the number of second in five minutes–to get the number of bits per second. This information is typically plotted on a graph showing its evolution in time and stored in a database.
One important thing to keep in mind is that what you get out of this process is average utilization in bits per second over a five-minute time span. Imagine a 100 Mbps interface. In the five minutes between samples, the actual traffic level could have been at 100 Mbps for 150 seconds and at 0 for 150 seconds and it would display an average bandwidth utilization of 50 Mbps although the interface was maxed out for half of the five minutes. This is a shortcoming of every SNMP monitoring system. It won’t give you instantaneous, live utilization figures. Some tools can use other means to get real-time traffic figures but they are not common. Five-minute averages are usually sufficient for most administrator’s needs.

The PRTG Network Monitor from Paessler AG is another one of the besbest-knownl-in-one monitoring tools. It is a feature-packed system which is among the fastest and easiest to set up and configure. According to Paessler, it can be set up in a couple of minutes. Our experience shows that while this might be a slight overstatement, it’s still very easy and quick to set up, thanks in part to its auto-discovery feature that will scan your network to find devices and automatically add them to the tool. Once the auto-discovery completes, further information on the detected devices can be retrieved using various protocols. The system uses a combination of Ping, SNMP, WMI, NetFlow, jFlow, sFlow, and it can also communicate via DICOM or the RESTful API.
The PRTG Network Monitor can monitor pretty much anything. It is based on sensors—which can be thought of as add-on that are built right into the product—that each have a specific purpose. For example, there are HTTP, SMTP/POP3 (e-mail) application sensors. There are also hardware-specific sensors for switches, routers, and servers. In all, the tool has over 200 different predefined sensors that can retrieve various staistics.
The PRTG Network Monitor offers a selection of user interfaces. You have the choice of an Ajax-based web interface or a Windows enterprise console as well as mobile apps for Android and iOS.
