This script provides a simple way to send results from rtl_433 directly to a Graylog server with very little setup. Pipe results from rtl_433 to rtl_433-graylog.py and it will format the results into a GELF message and fire them off to the Graylog server you specify. No need to set up extractors or set up other transport mechanisms. Quick and solid.
Quick background: https://github.com/merbanan/rtl_433 is a generic data receiver that uses an SDR receiver to listen to a frequency (or several, if hopping frequencies), and attempts to identify and decode broadcast messages from various devices. Sending results to Graylog allows you to query/chart/analyze the results over time.
Edit rtl_433-graylog.py and set the GL_SERVER variable value to your hostname or IP address of your Graylog server, and the port to the UDP GELF input port you configured on the Graylog server.
For example:
GL_SERVER=("192.168.20.12",12201)
Example 1, most basic use case:
$ rtl_433 -F json | ./rtl_433-graylog.py
Fundamentally, run rtl_433 with the "-F json" argument so that it formats all output as json, then pipe that to rtl_433-graylog.py.
Example 2, include additional metadata fields, like frequency, level info, protocol id; also using -v to print out the message on the console:
$ rtl_433 -M level -M protocol -F json | ./rtl_433-graylog.py -v
Example 3, tuning into 315MHz, include meta data, verbose messages to console
$ rtl_433 -M level -M protocol -f 315M -F json | ./rtl_433-graylog.py -v
