Go-ipfm (IP Flow Meter) is an standalone bandwidth analysis tool written in Golang. (no need to libpcap)
Core features:
Measure download and upload usage per ip
Save data to SQL database and text file
No dependence on libpcap
Runing on Linux and Unix based systems
Prerequisites: Golang + Git
Installing for linux - freebsd and macos. (linux is recommended)
Clone the code form Github or Snix servers.
# git clone https://slc.snix.ir/snix/go-ipfm.git # Snix
# git clone https://github.com/Sina-Ghaderi/go-ipfm.git # Github
# cd go-ipfm
# go get -v
# go build
# ./go-ipfm -inf eth0 -net 10.10.10.0/24 -svd database.db -ttf 5 -txt filename.txt
starting go-ipfm on eth0 interface, network 10.10.10.0/24, database database.db
...
#./go-ipfm -h
Usage of ./go-ipfm:
-hbm string
show (in txt file) data usage in <KB|MB|GB|TB> (default "MB")
-inf string
network interface to capture on <interface_name> (default "lo")
-net string
network to capture on <ipv4/cidr> (default "192.168.1.0/24")
-srf string
sort data in txt file based on <descending|ascending> (default "descending")
-srt string
sort data in txt file based on <TX|RX> (default "RX")
-svd string
database to save data <database_name> (default "ipfm.db")
-ttf string
time in second to flush data into the database <integer> (default "3")
-txt string
also save data to file <filename|false> (default "false")
So im runing go-ipfm on KVM host to measure vm's bandwidth usage
# ./go-ipfm -inf virbr0 -net 192.168.122.0/24 -txt data.txt
starting go-ipfm on virbr0 interface, network 192.168.122.0/24, database ipfm.db
...
Open data.txt file by using watch and cat command in linux:
# watch cat data.txt
Go-IPFM 0.34 - Capturing Data On virbr0 - Time: 2020-08-12 03:04:32
