The solution uses a custom SmartApp I’ve written to send data from SmartThings to InfluxDB. Grafana : Grafana is an open-source, general purpose dashboard that is used for visualizing time series data for Internet infrastructure and application analytics. InfluxDB: This is where we store the data that Grafana displays. Next we need to setup the input plugins. Copied URL can be used in this template node (submit the URL as msg.payload or paste the URL there). Temperature, pressure and humidity create the weather outside which changes based on location and time. It also contains a Makefile. Use this QR to keep me caffeinated with BTC: 2. In our example we use InfluxDB to store the data because it is optimized for time series data. Of cause it would also be possible to work with other databases like MariaDB or mongoDB but InfluxDB work right out of the box with Grafana, we use to visualize the data. Let’s grab the key and update the repo (execute one at the time). Embedding IoT charts in NodeRED running on Raspberry Pi. It makes perfect sense to track these 3 values at the same time and keep it as one measurement. Luckily it’s now much easier to collect SNMP data using Telegraf. Contribute This is why organising your data structure is important. For IoT precision of the DB should be set to seconds. I want to be able to share and embed my charts in NodeRED without logging in, to do so, I have to modify Grafana’s config file. Tags could be used to define a location of the measurement in case you want to monitor. In this section, we are going to configure Telegraf to gather system metrics on our Linux host (in this case, a Debian 10, but it works in the same way for Ubuntu-based hosts). We live in a world of data, big data. The road to mastering Grafana and InfluxDB is long and I’m far from understanding everything available there. You can follow The query returns the number of unique field values in the level description field key and the h2o_feet measurement.. Common Issues with DISTINCT() DISTINCT() and the INTO clause. When you set up the InfluxData time series platform, you will need a collection agent collecting your metrics. Select InfluxQL or Flux from the Query Language list. With several VMs and complex network setups there is nothing more satisfying than watching your system come to life in the form of a dashboard.
