Openbmp Basic File Consumer

A basic file consumer of OpenBMP parsed and RAW BMP Kafka streams. You can use this file consumer in the following ways:

  • Working example to develop your own consumer that works with either parsed or RAW BMP binary messages
  • Record BMP feeds (identical as they are sent by the router) so they can be replayed to other BMP parsers/receivers
  • Log parsed BMP and BGP messages in plain flat files

See Consumer Developer Integration for more details on the OpenBMP Kafka feeds and message syntax.

Parsed Log Format

The current format of the log messages are an attempt to be human readable. If you plan to use grep, awk or other tools to filter/interact with the flat files, then you will want to update src/bin/openbmp-file-consumer source file to change the logging format. You can easily change the format to whatever you want. For example, you can make it PIPE delimited, you can filter what's logged, etc.

Installation

You can either run the code within the git directory or you can install it in your python path.

If you are going to run it within the git directory, see running instructions.

Install Dependancies:

sudo apt-get install libsnappy-dev 
sudo pip install python-snappy
sudo pip install kafka-python
sudo pip install pyyaml

git clone https://github.com/OpenBMP/openbmp-python-api-message.git
cd openbmp-python-api-message
sudo python setup.py install

Installation of openbmp-python-api-message library is shown above.

You might have to install 'pip' if you don't already have that. You can do so using apt-get install python-pip python-dev

See Kafka-python Install Instructions for more details.

Install openbmp-file-consumer:

git clone https://github.com/OpenBMP/openbmp-file-consumer.git
cd openbmp-file-consumer
sudo python setup.py install

Running

If you install the python code, then you should be able to run from a terminal

openbmp-file-consumer -b <host e.g. kafka.openbmp.org> <base path for parsed message e.g. /var/openbmp>

If you are running from within the git directory, you can run it as follows:

PYTHONPATH=./src/site-packages python src/bin/openbmp-file-consumer -c src/etc/openbmp-file-consumer.yml

Usage

Usage: src/bin/openbmp-file-consumer [OPTIONS]

OPTIONS:
  -h, --help                  Print this help menu
  -c, --config                Config filename (default is sys.prefix/etc/openbmp-file-consumer.yml)

Configuration

Configuration is in YAML format via the openbmp-file-consumer.yml file.

Directory Structure

Files are stored hierarchical as depicted below. Files are rotated automatically after a size of 300MB. The max rotated file count is 20. You can adjust these settings if you wish by updating the src/bin/openbmp-file-consumer initLogger() function.
