Particle to Grafana

This page provides you with instructions on how to extract data from Particle and analyze it in Grafana. (If the mechanics of extracting data from Particle seem too complex or difficult to maintain, check out Stitch, which can do all the heavy lifting for you in just a few clicks.)

What is Particle?

Particle allows businesses to bring their Internet of Things (IoT) products to market faster. It provides a secure, easy-to-use, full-stack IoT cloud platform and low-cost connected hardware.

What is Grafana?

Grafana is an open source platform for time series analytics. It can run on-premises on all major operating systems or be hosted by Grafana Labs via GrafanaCloud. Grafana allows users to create, explore, and share dashboards to query, visualize, and alert on data.

Getting data out of Particle

Particle exposes events through webhooks. To use webhooks, log into your Particle console and click on the Integrations tab, then click New Integration > Webhook. Set the event name to the item you want to track; it's good practice to specify the name of the field where you want the data to live in your data warehouse. Set the URL to the key or token that you'll use to accept the data. Leave the request type as POST. In the device field, select the device you want to trigger the webhook. Finally, click Create Webhook.

Sample Particle data

Particle sends data in JSON format via webhook through a POST request whenever an event triggers it to do so. The JSON fields and endpoints will match the data collected by your form. For instance:

{
    "event": [event-name],
    "data": [event-data],
    "published_at": [timestamp],
    "coreid": [device-id]
}

Loading data into Grafana

Analyzing data in Grafana requires putting it into a format that Grafana can read. Grafana natively supports nine data sources, and offers plugins that provide access to more than 50 more. Generally, it's a good idea to move all your data into a data warehouse for analysis. MySQL, Microsoft SQL Server, and PostgreSQL are among the supported data sources, and because Amazon Redshift is built on PostgreSQL and Panoply is built on Redshift, those popular data warehouses are also supported. However, Snowflake and Google BigQuery are not currently supported.

Analyzing data in Grafana

Grafana provides a getting started guide that walks new users through the process of creating panels and dashboards. Panel data is powered by queries you build in Grafana's Query Editor. You can create graphs with as many metrics and series as you want. You can use variable strings within panel configuration to create template dashboards. Time ranges generally apply to an entire dashboard, but you can override them for individual panels.

Keeping Particle data up to date

Once you've coded up a script or written a program to get the data you want and move it into your data warehouse, you're going to have to maintain it. If Particle modifies its API, or sends a field with a datatype your code doesn't recognize, you may have to modify the script. If your users want slightly different information, you definitely will have to.

From Particle to your data warehouse: An easier solution

As mentioned earlier, the best practice for analyzing Particle data in Grafana is to store that data inside a data warehousing platform alongside data from your other databases and third-party sources. You can find instructions for doing these extractions for leading warehouses on our sister sites Particle to Redshift, Particle to BigQuery, Particle to Azure SQL Data Warehouse, Particle to PostgreSQL, Particle to Panoply, and Particle to Snowflake.

Easier yet, however, is using a solution that does all that work for you. Products like Stitch were built to move data from Particle to Grafana automatically. With just a few clicks, Stitch starts extracting your Particle data via the API, structuring it in a way that's optimized for analysis, and inserting that data into a data warehouse that can be easily accessed and analyzed by Grafana.
