Steelhead provides an extremely flexible reporting interface to allow you to quickly track, graph, and export your plant's data.

The reporting tool leverages a sandboxed SQLite database that allows you to perform complex queries in - by far - the most commonly used query language in use today. For some basic tutorials on SQLite, visit sqlitetutorial.net/sqlite-select/ (link out).

Native reporting features like Insights, for historical data, and the Watch Tower, for active data, are also available for common queries.

Creating a Report

Navigate to Reports.

Here you will see an interface that will allow you to create a new query for your data. Data that you can query (tables) are listed on the left hand side.

Run a simple query

In the query editor window enter:

select * from users;

And click "Run Query" in the toolbar at the top of the page. You will see a result of your users in the plant. This simple query by itself isn't particularily useful, however, it can be used to join with other data to get per-user metrics.

To quickly generate a select * from query for a table, right click on the table and click "Run Select All Query".

You can download your result by clicking "Download Data" in the toolbar and it will download a CSV file, these files can easily be imported into excel.

JSON Queries

Custom inputs (for example operator inputs on part transfers) are stored as JSON. These inputs can be queried using the json_extract function of SQLite.

The example below shows a list of parts transfers that have a custom field created on it with a "pH" entry.

To create a report of the pH at a specific process node over time we can use a query like the following snippet where derived_from is the id of the process node you are interested in generating a report for.

select json_extract(from_node_custom_input,'$.pH') as pH 
    from parts_transfer where from_recipe_node_id 
    in (select id from recipe_node where derived_from = 2)

In the result below you can see the pH level and the time that pH level was taken.

Charting

Using the example above, we can generate a chart to show this data. To create a chart, click on the "Charts" tab and click "Add Chart".

Fill out your desired data, chart type, etc. and choose which fields you would like on your x and y-axis.

Click "Update Chart" and you will see your chart appear.

View mode can be activated with the toggle on the top right of the chart editor. View mode allows you to hide the editor and just view the charts. Saved charts are loaded in this mode to start.

Downloading charts can be done by clicking the cloud icon on the top right of the chart you wish to save as an image.

Saving

Reports can be saved using the "Save Report" button in the toolbar. Give the chart a name in the popup dialog.

Loading Saved Reports

Saved reports can be loaded by clicking the report in the bottom left.

Reports can also by found by searching by name in the global search.
