We understand the headache that network administrators go through when monitoring network traffic, bandwidth usage, load-balancing, network devices, etc. Overloaded routers can represent a risk for your company’s communication system. This is why network admins should count on reliable IT Infrastructure monitoring tools, such as the software we are going to talk about.
As you look for powerful and affordable tools, there are some extra features that you should not miss. For example, port management, traffic analysis, and even network security.
Here is our list of the eight best router monitoring software and tools:
- SolarWinds Network Insight for Cisco ASA Monitoring – EDITOR'S CHOICE A group of software products that includes the Network Performance Monitor.

What should you look for in router monitoring tools?
We reviewed the market for bandwidth and traffic management tools that communicate with routers and analyzed the options based on the following criteria:
- A service that can collect performance data from switches and routers
- A service that is able to use SNMP for status querying
- An alerting mechanism to warn of impending problems
- A dashboard that shows live performance data
- An autodiscovery function for automated device enrollment
- A free trial or a free package
- A free tool that is worth installing or a paid tool that offers value for money
With these selection criteria in mind, we have found monitoring systems that will query switches for their statuses as well as watching over router performance. Our selection includes packages that will install on Window and Linux.

Router monitoring FAQs
How do you monitor a router?
You can monitor a router directly by connecting to it over the internet and accessing its management control panel. The exact range of information shown in this console and the menu location of performance data depends on your router’s make and model. The easiest way to monitor router health and performance is to use a network monitoring tool.
Can you monitor Internet traffic through a router?
All router types will give information on Internet traffic. If the router is being used as a gateway, it is only necessary to query the traffic statistics of one interface in order to get Internet traffic data. If the router is placed within the network, you should query traffic by source and destination IP address and aggregate data related to those packets that have addresses from outside the network.
How can I monitor free traffic on my router?
Traffic space that is still free and available for use can be calculated by accessing the capacity data for your router per interface and also the full CPU c\apacity of the device. Next, watch the live throughput statistics. The gap between current throughput and the device’s capacity is free for processing extra traffic.
