Slides

Presentation given at Golang Melbourne, July 4th 2017

Getting started

The steps below assume Docker for Mac/Windows or via Linux, meaning exposed ports are accessible at http://localhost:<port>. If you're using Docker via Virtualbox/Vagrant/other, please substitute localhost for your IP.

1. Clone the repo

2. Run docker-compose up. This will bring up:

• Mosquitto (MQTT broker)
• InfluxDB (time series database)
• Grafana
• mqti
• MQTT temperature generator
• MQTT geo generator

3. The following UI's are now available:

• InfluxDB (root/root)
• Grafana (admin/admin)

4. Access the Grafana UI, logging in as admin/admin

5. Add a new data source with the following detail:

• Name: influxdb-iot
• Type: InfluxDB
• HTTP URL: http://influxdb:8086
• HTTP Access: proxy
• InfluxDB Database: iot

6. Click 'Add'

7. Add another new data source with the following detail:

• Name: influxdb-owntracks
• Type: InfluxDB
• HTTP URL: http://influxdb:8086
• HTTP Access: proxy
• InfluxDB Database: owntracks

8. Now, let's import a dashboard

9. Click 'Upload .json File' and select './grafana/IoT-dashboard.json'

10. Leave the name as 'IoT' and select 'influxdb-iot' from the 'Select a InfluxDB data source' drop-down

11. Click 'Import'. Your new IoT dashboard should already be showing data!

12. Now, let's import another dashboard

13. Click 'Upload .json File' and select './grafana/Owntracks-dashboard.json'

14. Leave the name as 'Owntracks' and select 'influxdb-owntracks' from the 'Select a InfluxDB data source' drop-down

15. Click 'Import'. Your new Owntracks dashboard should already be showing data!
