BandwidthD A free, open source network bandwidth analyzer that has become a little out of date.ManageEngine NetFlow Analyzer A useful tool for detecting traffic problems, identifying bandwidth hogs and peak traffic times.Cacti A free, open source network data analyzer templates for network topology mapping.Available for Windows, Linux, macOS, Raspberry Pi, and Unix. nTop-Ng Available in free and paid versions, this network traffic analyzer has a simple and unsophisticated interface.Noction Flow Analyzer This on-premises monitoring system delivers network traffic monitoring for live activity and a capacity planning analyzer based on historical traffic data.SolarWinds NetFlow Traffic Analyzer – FREE TRIAL A bandwidth monitoring system that can be used for live monitoring and also historical traffic pattern analysis.Paessler PRTG Bandwidth Monitoring Tool – FREE TRIAL Part of a wider package of system monitoring tools, this service offers a range of sensors to supervise traffic flows.SolarWinds Real-Time Bandwidth Monitor – FREE TRIAL A free tool that will demonstrate traffic flows on a network.Here is our list of the best bandwidth monitoring tools: That file is located at /mnt/data/ntopng/redis.A couple of years ago, I was asked to consult on a project: an organization was getting a lot of bandwidth from their ISP but they couldn’t figure out why connecting to the Internet was still very slow.Īfter spending a few days on the client’s site, I eventually discovered that the source of their problem was a faulty router interface that was dropping more than half of the bandwidth they were receiving from their ISP. You can also customize the settings for the redis database if you want to eliminates database saves to storage. This will also consume additional CPU and memory resources so be careful with this option. NOTE If you comment out the -i interface and let ntopng startup listening to all interfaces you will have to wait up to 30 seconds for all interfaces to register. The default is -i=br0 (LAN), n=1 ( Decode DNS responses and resolve all numeric IPs ) and -W3001 (enable HTTPS port) You can edit the file /mnt/data/ntopng/nf on the UDM to change the settings. The default instance will listen on the LAN interface (br0). Anytime the docker container is started it will run a geoipupdate to download the latest GeoIP data. Once you are done you can start the container. When prompted on the version of geoipupdate select the option for older than 3.1.1. Step 0 (geoipudate) has been done for you as it's included in this image. You can use scp or winscp to transfer the file over. Follow the instructions from the link below and save the downloaded nf file on the UDM in the path /mnt/data/ntopng/nf. If you want to see country flags next to hosts you'll need to setup a free account with. If you're interested in compiling your own version I have a Dockerfile available here that compiles ntopng from source: GeoIP integration In order to install this image you will need to log into the UDM via ssh and type the following command:įortunately you can also take advantage of boostchicken's great tool to automatically start a Docker container after a reboot: You can optionally configure the timeseries database to point to an external Influx database. In addition, the timeseries database (RRD) does not require much disk space. ntopng uses an in memory database known as redis so writes to disk are minimal. The Docker image has been configured to perserve data between upgrades. This is a prebuilt image of ntopng to run directly on an UDM or UDM PRO.
