Cisco router monitoring: 3 key questions

When it comes to Cisco routers, which parameters can I monitor?

Among other things, you can monitor the availability, network traffic, and quality of service of your Cisco routers. With the right monitoring tool, you'll be notified immediately in the event of errors or disruptions.

NetFlow is a protocol developed by Cisco to monitor Cisco routers and other Cisco devices. NetFlow lets you analyze your bandwidth and determine which IP addresses, applications, and protocols are generating the most traffic.

How do I choose the right Cisco router monitoring software?

For centralized monitoring, go with a tool that works with the devices of all kinds of different manufacturers. Cisco routers are configured to send NetFlow packets to PRTG. All monitoring data is displayed on a single dashboard. If errors or disruptions occur on a Cisco router (or in your traffic), you'll be notified at once.

The PRTG Sensor Hub provides a detailed look at our sensors. Upon installing PRTG Network Monitor, you’ll be able to access all our sensors and features for 30 full days. After this time, you can continue to use up to 100 free sensors for as long as you like.


Monitoring Cisco router traffic

With PRTG, a quick glance is all it takes to check the traffic in your Cisco routers. The SNMP Traffic Sensor displays incoming and outgoing traffic, as well as total traffic. 


Monitoring data packets in Cisco routers

There are many ways to monitor the data packets that flow through your Cisco routers. Our native NetFlow sensors and SNMP sensors are specially
designed for Cisco devices.


Monitoring the quality of service
of Cisco routers

In today’s world, video conferencing is used by nearly all companies. And when it comes to video calls, nothing matters as much as the quality of the connection. Our Cisco IP SLA Sensor monitors the quality of service of your network. Among other things, it measures packet loss and jitter.


Monitoring the Internet connection
on Cisco routers (ADSL)

PRTG monitors the various speeds and attenuation values of your ADSL connection. It lets you set your own threshold values, and notifies you if these values are exceeded. As a result, you can make sure you always have enough bandwidth. And thanks to clear-cut PRTG monitoring data, you can easily convince higher-ups of the need for additional resources or upgrades.


Monitoring Cisco router hardware

If you’re a sysadmin, then you’ve probably had to deal with router failure caused by a hardware issue. Perhaps your memory was full or your CPU was overloaded. Some routers heat up in certain situations and shut down automatically. With our Cisco Health Sensor, you can monitor these parameters and more.

Cisco routers and comprehensive monitoring: 3 case studies

A university network

“Greg Graeff and his team are in charge of the data traffic on 50 IBM servers, 125 Cisco and Alcatel switches and routers on 250 IBM desktop PCs in the labs, and the PCs of all faculty and staff.”

To the case study

IT infrastructure of a housing provider

“UNITE currently uses 7,000+ sensors to monitor its Cisco devices (routers, switches, voice gateways, firewalls), Windows servers (SQL database servers, email servers, file servers, domain controllers, web servers), VMware infrastructure (VMware hosts/SAN infrastructure), and more.”

To the case study

Network of an IT consulting firm

“Most of our systems are Windows-based, but we also have a few Linux systems and some websites. In total, we use 400 PRTG sensors and 14 remote probes. We monitor bandwidth for 20+ firewalls and a combination of Cisco and Zyxel routers.”

Practical tip: “Hey Gerald, what would you tell administrators looking to use PRTG as a NetFlow Analyzer?”

“Cisco has continuously developed the NetFlow technology. Administrators must therefore find out beforehand which NetFlow version is supported by their routers and switches. With the right PRTG sensors, setting up NetFlow monitoring is quick and easy.”
