How to check router traffic

Here's a quick summary about router checking with PRTG:

  1. Install and run PRTG Network Monitor 
  2. Choose one of following options for router monitoring protocols according to your router specifications: SNMP, NetFlow/jFlow/sFlow or Packet Sniffing. 
  3. See the bandwidth consumption of individual connections and all network activities at a glance and create individual dashboards.
  4. Set up custom alarms and you’ll be notified in case of router errors or overloads.

Prevent network failures and bottlenecks with PRTG Router Monitoring


Overloaded routers (and thus networks) can slow down a company's communication and workflow.

PRTG Network Monitor, our network monitoring solution, allows you to check all your router connections. Determine how much bandwidth is used per connection, the devices, programs, or users which generate the most traffic, and where bottlenecks occur in your network. You'll get a ton of valuable information which will make your work as an administrator that much easier. PRTG supports routers from all the major manufacturers like Cisco, Dell, Linksys, TP Link or Netgear.

With its wide range of features, PRTG Network Monitor makes it easy to monitor your router traffic around the clock, log network activities, and calculate network utilization.

You'll be notified automatically whenever something seems amiss inside your router or network traffic. PRTG lets you act quickly to prevent bandwidth bottlenecks from paralyzing your network.

Thanks to PRTG, the entire staff can work with peace of mind.

Here's what Monitoring looks like in PRTG


Router Monitoring
with PRTG





i NetFlow is a protocol for collecting, aggregating and recording traffic flow data in a network. NetFlow data provide a more granular view of how bandwidth and network traffic are being used than other monitoring solutions, such as SNMP. NetFlow was developed by Cisco and is embedded in Cisco’s IOS software on the company’s routers and switches and has been supported on almost all Cisco devices since the 11.1 train of Cisco IOS Software.

Router checking with PRTG supports three methods which come with their own advantages and disadvantages:


The network protocol SNMP is the easiest way to calculate traffic. CPU and network loads remain low. However, it is not possible to analyze protocols or IP addresses.

Packet Sniffer

A built-in PRTG Packet Sniffer lets you examine all network data packets for protocols or IP addresses. But of the three methods, this one generates the highest CPU and network load.


The NetFlow/sflow/jFlow methods belong to the routers of certain providers such as Cisco, HP, or Juniper. Bandwidth utilization is calculated within each device and transmitted to PRTG for analysis and disclosure. The most powerful of the three alternatives when both CPU and network loads are low, this method is especially suitable for networks with a great deal of traffic.
