Stream last value table module

You can use the stream last value table module to monitor the last recorded value on a set of streams at a glance.

Prerequisite: Persist last known value setting

Before you can monitor the last value of a stream in the stream last value table, you'll have to enable Persist last known value on that stream. When this setting is enabled on a stream, it will cache the last datapoint ingested until a new datapoint is ingested. If this setting is disabled, the stream will not be able to supply data to the stream last value table module.

Step 1: Create a stream last value table module

  1. In Formant, navigate to the device view to which you want to add a stream last value table module. You can do this by going to Settings >> Views and selecting the view you want, or by clicking on your device, going to the desired view, and clicking the dropdown arrow next to the view >> Edit... >> Edit Layout.
  2. In the Edit Layout window, click Add Module >> Stream last value table.

Step 2: Configure your module
