Best MRTG Alternatives for System and Network Traffic Graphing


Marc Wilson

MRTG, Multi Router Traffic Grapher, is a great tool that is written in Perl that gives your details about networked devices that can be polled and monitored using SNMP.

In terms of functionality and using it to keep an eye on your traffic loads, it works well – As for other bells and whistles that many admins and engineers are looking for, it lacks quite a bit.

We want to list a some MRTG Alternatives for Windows and Open-source platforms, as well as some benefits to each replacement.

Some reasons that network engineers are looking to switch away from MRTG and find a suitable alternative are:

  • Lack of Updated and Intuitive Graphical Interface
  • Expand-ability and Scaling to multiple system types
  • Flexible Alerting and Notification System
  • Additional Monitoring Options
  • Intuitive and Easier Installation, Configuration and Updating
  • Better Support, Community and Active Forum
  • Consistent Software Updates

These are just a few reasons why folks are looking for replacements to MRTG. Below you'll find a quick list of the best software packages that we think would be suitable for traffic and system monitoring.

Here's the Top MRTG Alternatives/Replacements:

We'll break this up into 2 categories – First we'll cover Windows alternatives and then Open-source versions. Some of the package listed below have FREE or Freeware versions available for use with either a Time limit or Certain number of Sensors/Devices your allow to monitor.

1. Solarwinds Network Performance Monitor

solarwinds npm

Solarwinds NPM is another Excellent option to MRTG, considering there vast Market share and constant updates to NPM, its no wonder they are at the head of the game in terms of Network Monitoring and Management.

Solarwinds has integrated proprietary technologies into their Network Performance monitoring software that gives you an in-depth look into your network and bandwidth and lays it out for you in a way that is easy to digest and take action.

There NetPath feature helps you analyze and pinpoint issues at each “hop” in your network. This takes all the guess work out of finding which node is bogging down your bandwidth and helping your drill down the critical path of your network traffic. From there, you can solve the issue quickly and move onto optimizing your network speeds in order to provide the best user experience for your users.

Netpath is one of the most visual and intuitive ways to spot a bandwidth bottleneck in your network – with info such as Utilization rates, latency in milliseconds, packet loss, error rate,  and hop count, you can drill down to see where the issue is immediately. See Image below for a detailed screenshot of how Netpath looks:

Some features of NPM include the following:

  • Hop by Hop (Netpath) Analysis and Graph of traffic
  • Wifi and Wired Network Mapping (Dynamic)
  • Wireless (wifi) Network Monitoring
  • Capacity Forecasting, Alerts and Reports
  • Performance and Availability Monitoring for detecting Faults
  • Easy Installation with Automated Network Discovery/Mapping
  • Easy to Use Interface with is Customizable
  • Packet Capturing and Packet Sniffing (Netflow, sFlow, jFlow, Netstream and IPfix compatible)
  • Hardware Monitoring, Alerting and Notifications
  • Low Minimum system requirements to Run NPM (Deploy on Test VM if necessary!)

Solarwinds NPM is one of the Top contenders for Network Graphing and Monitoring – They offer a 30 Day Free Trial below – We suggest you Download and Get it installed on a Test Server or VM to really see the features we've covered above – The NetPath feature alone makes this software a game-changer!

3. ManageEngine OpManager

manageengine opmanager

ManageEngine OpManager has come a long way in recent years and has proven to be a suitable replacement for traffic graphing and monitoring. OpManager has a great feature set that will prove to be useful in any infrastructure, including many features that MRTG lacks. We've detailed a FULL Opmanager review here, some main features of OpManager include:

  • Bandwidth Analysis
  • Server and Network Monitoring
  • Log Management for your Perimeter Devices (Firewalls, etc)
  • IP Address Management for Switches & Config Management

ManageEngine OpManager also provides a limited Free version with up to 10 Devices to monitor.

Now we'll highlight some Open-source successors that have the same or more features and options as MRTG.


4. Nagios Core

nagios core

Nagios, as well-known as it is in the IT community, has a commercial version as well as a Open source version, known as the Core. Nagios has been around for some time now and has made a name for itself, so no introduction is necessary.

Some features of Nagios include (full feature list can be seen here):

  • Monitor Devices using SNMP, POP3, HTTP, PING, NNTP, etc)
