Hi all,
I am trying to track bandwidth on my network. I would like to view it per IP and get time series reports. (e.g. usage by client hourly, daily, weekly or monthly.) . My preference would be see this data both numerically and graphically. I can easily install both the app and required DB infrastructure, if required.
My goal is understand the bandwidth hogs on my network and identify unexpected changes which could suggest problems. Regarding how I capture the data, ideally I would use packet capture from a mirrored port, but I could also use Netflow/IPFIX if needed. (I could use SNMP too, but it does not seem to provide the desired granularity.)
I have looked at many tools and many of them seem to focus on much larger management paradigm including things like server agents, and yet, they do not seem to provide the granularity that I want for bandwidth. Ironically, I installed a tool on a friend's DD-WRT router which does exactly what I want, but I am not using DD-WRT.
I am currently testing NTOPNG and the free version does not offer this functionality as all time-series data seems to only be available in the full version. (I am considering licensing the full version, but even that seems to make it hard to find the data that I want.) My preference is for a Linux-based tool for simplicity and resource usage. I prefer open source for cost reasons.
Does anyone have any recommendations on solutions to try out?
Thank you!
