Flexible Visualization of TTN Data

This page describes installing Grafana and InfluxDB on openSuse 42.2. It also describes how to configure apache 2.4 to recieve data from a Things Network applications HTTP integration and store it in an InfluxDB database. Finally it shows how to create a Grafana dashboard to display the data from the InfluxDB.

InfluxDB

Installing InfluxDB

Here is the Download Portal Currently, it tells me to 

wget https://dl.influxdata.com/influxdb/releases/influxdb-1.7.9.x86_64.rpm
sudo zypper install influxdb-1.7.9.x86_64.rpm

It warns about missing package shadow-util. On openSuse this is named shadow and is installed -> ignore.

To use systemd for managing the database service, copy the service file 

sudo cp -av /usr/lib/influxdb/scripts/influxdb.service /etc/systemd/system/

For later versions of openSuse, Influx Installation Documentation suggests using a repository - should have the same results: 

sudo zypper ar -f obs://devel:languages:go/ go
sudo zypper in influxdb

Configure InfluxDB

sudo vi /etc/influxdb/influxdb.conf

Start InfluxDB

sudo systemctl daemon-reload
sudo systemctl enable influxdb
sudo systemctl start influxdb
sudo systemctl status influxdb

Test InfluxDB

Call the CLI and insert some test data. More details here: https://docs.influxdata.com/influxdb/v1.7/tools/shell/ 

influx
 CREATE DATABASE my_test_db
 USE my_test_db
 INSERT my_table,my_key=my_test my_value=1
 INSERT my_table,my_key=my_test my_value=2
 INSERT my_table,my_key=my_test my_value=3
 SELECT * FROM my_table
 QUIT

Grafana

Install Grafana

Here are the installation instructions. Basically just do 

wget https://dl.grafana.com/oss/release/grafana-6.5.2-1.x86_64.rpm 
sudo zypper install grafana-6.5.2-1.x86_64.rpm

It complains about missing urw-fonts, but they are not really required -> ignore. Also accept there is no signing key

Start Grafana

sudo systemctl daemon-reload 
sudo systemctl enable grafana-server.service 
sudo systemctl start grafana-server.service 
sudo systemctl status grafana-server.service

Test Grafana

Open http://localhost:3000
