Step 5: Deploy Grafana

warning

This is the 5th step of the guide "Deploy a Data Monitoring Solution". If you haven't done so already, jump back to the first step.

Overview​

Grafana is an open-source data-visualization platform that takes the data collected by your edge nodes in InfluxDB and translates it into beautiful and informative dashboards.

Add Grafana to your library​

Congratulations! Your Grafana is running and ready to start visualizing data from InfluxDB database!

Access Grafana Home​

You can access the Grafana GUI while the app is running through a web interface. Typing the following route in a web browser {IP_DEVICE}:13000, where {IP_DEVICE} is the Edge Node’s IP address that appears in the Networking card.

To log into the Grafana, use as credentials the values for USERNAME and PASSWORD you defined when you configured the app before deployin it.

(If you left the default values, then the credentials will be bbruser and bbrpassword)

  1. Enter following query in the editor:
from(bucket: "bbrbucket")
  |> range(start: v.timeRangeStart, stop:v.timeRangeStop)
  |> filter(fn: (r) =>
    r._measurement == "testDevice" and
    r._field == "testVariable"
  )
  1. Press the button Run query.
  2. You will see the data visualized in the graphic chart.
