pmacct is a monitoring tool for network management tasks. Data collected can be used for analysis and troubleshooting purposes to maintain the health of the network. pmacct can collect, replicate and export network information. It can cache in memory tables, store persistently to SQLite3 and output to flat-files like CSV, formatted, and JSON.
To monitor data usage (IP-based or MAC-based data accounting) down to the client level. Net-Traffic will monitor traffic for the entire RED, GREEN, etc. networks, but it cannot pinpoint which client is using lots of data. Connections will take a snapshot but only show day-by-day sums. pmacct can help admins keep tabs on users that use too much data.
My ISP implemented data caps and I occasionally over-run my limit. When that limit is exceeded I pay $10 for every additional 50GB of data use ($100 max). Ouch!
pmacct can be installed with the Pakfire web interface or via the console:
pakfire install pmacct
There is currently no web interface for this Addon. To run this Addon open the client console or terminal and access the IPFire box via SSH.
Data is stored in a memory table and can be fetched via the pmacct command-line client tool
pmacct. The memory plugin is recommended for prototyping and proof-of-concept and smaller-scale / home production environments.
/etc/pmacct/pmacct.conf and configure pmacct similar to this:
! ! "plugin1" plugin configuration ! plugins: memory[plugin1] plugin_buffer_size[plugin1]: 102400 plugin_pipe_size[plugin1]: 10240000 imt_mem_pools_number: 256 imt_path[plugin1]: /var/spool/pmacct/plugin1.pipe aggregate[plugin1]: src_host, src_port, src_mac, dst_host, dst_port, dst_mac, proto aggregate_filter[plugin1]: ip
Note - Learn about the above keys & values and their description at:
pmacct.conf file is modified, then run the command:
To test pmacct, run this command:
pmacct -p /var/spool/pmacct/plugin1.pipe -s
The output will be similar to this:
pmacct -p /var/spool/pmacct/plugin1.pipe -s -T bytes
The memory mode allows easily data injection into 3rd party tools like GNUplot, MRTG, RRDtool or a Net-SNMP server. See pmacct/EXAMPLES at master · linsomniac/pmacct

Note - a HUGE thank you to Erik who introduced us to pmacct in 2015, built evaluation versions, and supported pmacct over the years. And to Adolf who built and submitted the current version for review. And thanks to both of them for answering WAY too many of my goofy questions!
