About
FlowTrack is designed to listen for and log netflow (v5) traffic. My goal with it is to make installation as easy as possible. There's no need to configure an external webserver or database. When you run FlowTracker a small webserver is started, and a netflow collector is started.
Initially I'm focusing on feature set and simplicity of installation. Scalability is a secondary concern right now. I'm testing with very light traffic. In otherwords, this will likely melt under high load. If you do try running this under high load, let me know how it goes.
I'd love to know if you're using it. Questions? Bugs? Feature Requests? Open them as issues on GitHub
Installation & Use
Requirements
(I will likely add new stuff to this list, such as rrdtool):
- Perl 5.10+ (tested on 5.16.1)
- Mojolicious
- Net::Server
- Log::Log4perl
- YAML
- DBI
- DBD::SQLite
- Net::Flow
- Net::IP
- Something to send you v5 netflow data (rflowd on dd-wrt works great!)
- a working SQLite installation
Installing
I recommend cloning the repository to make getting updates etc. easier.
git clone git://github.com/skarfacegc/FlowTrack.git
Configuration
flowTrack.conf
# Port to read for netflow
netflow_port: 2055
# Name of the database
database_name: FlowTrack.sqlite
# What do you consider your internal network
# Not used in version 0.01 Will be used to determine ingress/egress
internal_network: 192.168.1.0/24
# Where to write data (database/logs/etc)
data_dir: ./Data
# How many seconds to keep raw flows around
# Defaults to a half day
purge_interval: 43200
# Port for the webserver
web_port: 5656
# Log4Perl Configuration file
logging_conf: flowTrackLog.conf
# Location of pid files
pid_files: ./log
Run FlowTrack.pl
./FlowTrack.pl [--config=/location/of/config/file.conf]
Logging is configured in flowTrackLog.conf Defaults to logging in ./log
URLs
Point your browser at http://localhost:5656/
The following URLs do things:
-
http://localhost:5656/
This is the main page (currently points to /FlowsForLast/1) -
http://localhost:5656/FlowsForLast/1
Shows flows for the last 1 minute. Change the 1 to another number to expand your time range. -
http://localhost:5656/json/FlowsForLast/1
Raw data for the above
Tuning
You can tune the collector pool by twiddling these values in FT/FlowCollector.pm
min_spare_servers => 3,
max_spare_server => 5,
max_servers => 5,
max_requests => 5,
