About
Kotori is a multi-channel, multi-protocol, telemetry data acquisition and graphing toolkit for time-series data processing. Free, open, simple. It supports scientific environmental monitoring projects, distributed sensor networks, and likewise scenarios.
Details
Kotori is a data historian based on Grafana, Mosquitto, and InfluxDB, and is written in Python with Twisted. The best way to find out what you can do with Kotori, is by looking at some outlined scenarios and by reading how others are using it at the example gallery. To learn more about the technical details, have a look at the used technologies.
Features
Multi-channel and multi-protocol data-acquisition and -storage. Collect and store sensor data from different kinds of devices, data sources, and protocols.
Built-in sensor adapters, flexible configuration capabilities, durable database storage and unattended graph visualization.
Based on an infrastructure toolkit assembled from different components suitable for data-acquisition, -storage, -fusion, -graphing and more.
Leverage the flexible data acquisition integration framework for building telemetry data acquisition and logging systems, test benches, or sensor networks for environmental monitoring systems, as well as other kinds of data-gathering and -aggregation projects.
It integrates well with established hardware-, software- and data acquisition workflows through flexible adapter interfaces.
Installation
Kotori can be installed in different ways. You may prefer using a Debian package, install it from the Python Package Index (PyPI), or run it within a development sandbox directly from the Git repository.
Corresponding installation instructions are bundled at https://getkotori.org/docs/setup/.
Synopsis
A compact example how to submit measurement data on a specific channel, using MQTT and HTTP, and export it again.
Data acquisition
First, let’s define a data acquisition channel:
CHANNEL=amazonas/ecuador/cuyabeno/1
and some example measurement data:
DATA='{"temperature": 42.84, "humidity": 83.1}'
Submit with MQTT:
MQTT_BROKER=daq.example.org echo "$DATA" | mosquitto_pub -h $MQTT_BROKER -t $CHANNEL/data.json -l
Submit with HTTP:
HTTP_URI=https://daq.example.org/api/ echo "$DATA" | curl --request POST --header 'Content-Type: application/json' --data @- $HTTP_URI/$CHANNEL/data
Data export
Measurement data can be exported in a variety of formats.
This is a straight-forward example for CSV data export:
http $HTTP_URI/$CHANNEL/data.csv
