Paul Ferrill The Best Network Monitoring Software of 2018 Poor bandwidth and network utilization can affect the productivity of every user connected to your corporate network. We test 10 network monitoring solutions that can help you keep your company's network running reliably. What Is Network Monitoring? Network monitoring services are a critical component to keeping a company's data center healthy and functioning. These services detect, monitor, and analyze your network, examining applications and devices in real time, which can help you quickly respond to warning alerts.

Because of this, it's imperative that IT organizations properly manage these services. Years ago, unreliable networks used to result in delays in email or something else for which it was easy to find a workaround.

Today, however, an unreliable data network can literally bring a business to a standstill. For instance, if the systems attached to your network can't get an IP address by using (DHCP), then they won't be able to communicate with any other system.

Similarly, if (DNS) isn't functioning properly, then your systems won't be able to look up the address of any system on the internet. The way in which you manage bandwidth and network utilization will directly affect the productivity of all users connected to your corporate network. To help you, we've tested and compared 10 of the top network monitoring software solutions available today. Most are cloud-based and all of them can help you keep your users connected and your network pipes safe.

Some of those services cross over into the category of infrastructure due to the criticality of the service. Monitoring services such as DNS then becomes more of an issue as opposed to a network consideration. DHCP probably fits the same description, although the managing of a DHCP service would be something for which a network administrator would typically be responsible. (SNMP) was first introduced in 1998 under (RFCs) 1065, 1066, and 1067. SNMPv2 and SNMPv3 have, for the most part, replaced the initial version and have seen widespread adoption across a variety of platforms. While SNMP is most frequently associated with networking, you can also configure operating systems (OSes), to include Microsoft Windows, to respond to SNMP commands. A key consideration for network management tools should be how they use SNMP to accomplish their tasks.

If you really want to know what's happening on your network, then you'll need to learn something about network flows. Was originally introduced for Cisco routers, providing the ability to analyze IP network traffic entering or exiting a specific interface. Flow data is sent to a collection point (typically a system running a database) to make query-based analysis easier. Other switch manufacturers followed suit, along with other similar sampling tools such as. A large number of including Arista Networks, Brocade Communications Systems, Hewlett-Packard, and others provide native sFlow support. You can find a full description of sFlow under. Important Features A number of key features stand out as specific needs to adequately fulfill the role of network management.

For one, from an administrator's perspective, it's nice to have visual graphics that give you a quick overview of the current system status. Having the ability to tweak the arrangement of graphical elements on a dashboard is an added plus. Providing a mechanism to alert someone of a problem is necessary across the board. (IPAM) has become a vital capability for many large organizations. Keeping track of statically assigned addresses, along with a large number of DHCP pools, can't be adequately managed with a manual system.

Integrating IPAM with a network management tool just makes sense as the same person quite frequently handles both functions. Automation is the key to managing large numbers of devices. The more you can automate small administration tasks, the more efficient the process becomes. Automated alerting and repair fall into this category and represent a key differentiator between products.

Add to that the ability to remotely connect to your monitoring system, and you have the makings of a solid product. (SDN) is a hot topic and not without a significant level of confusion—unless you happen to be either a vendor or a technologist with a vested interest. At a very high level, the term SDN is used to describe the functional separation of the network control plane and the forwarding plane, making it possible to dynamically configure data paths for optimum performance. None of these products really get into SDN, except at the top level of monitoring the performance of a switch. How We Tested In this roundup, we call out several areas to help focus the evaluation. While installation and setup is something you really only do once, it's still an area of interest.

For the network management category, the initial configuration may include making changes to your switches in order to enable the transmission of NetFlow or sFlow data. Changes to production switches typically require a significant amount of justification and approval prior to implementation. It would be prudent to prove any of these test methods on a small test network before moving onto any larger environment. That being said, we used an managed switch as the primary sFlow source. Enabling sFlow on the switch required the entry of a number of commands at the switch (CLI) over an connection. We also had to upgrade the switch firmware to the latest version for everything to work correctly. At least one product (ManageEngine OpManager) provided a script to enable sFlow along with a one-page 'how-to' document to do that for you.

From an administrator's perspective, the user interface (UI) must be easy to navigate and customize. It should quickly present any problem areas and allow an operator to drill down for more specifics without a huge number of clicks. The customization of the UI and management of features must not require a programmer to make it properly work. Alerting is a basic requirement, with the ability to customize the priority and delivery an equally important feature. Reporting should be equally as easy to administer. Creating a new report with a query specific to the information of interest should not require a database administrator. Extra points are given here for useful graphics and multiple export formats.

Role-based access may not be a big deal for a small organization but it would be for a group with multiple IT administrators. The bottom line with network management is to keep the network smoothly functioning, with an eye on overall usage. Having the ability to see trends and potential problems can help stave off any future problems and add value to any product. How to Buy The first step for any IT project is to define the requirements. For network management tools, the foundational pieces include the ability to see detailed information about key pieces of hardware such as switches and routers. Many organizations don't have the staff to monitor computer screens 24/7. Automated alerting and remediation would be a key requirement in that case to help reduce the administrative manpower required.

Trend-based reporting and monitoring help determine utilization levels and identify potential bottlenecks before they become a problem. Good reporting tools would be another requirement, to include the ability to create customized reports and queries. Once you have that list of essential requirements, you should be able to look at each one of these products and determine if they meet those requirements or not. If more than one product qualifies, you'll need to do some testing on your own to see which one best suits your needs.
