After completing this workflow, FlexLogger telemetry is available in Sift for analysis, either streamed live during a test or uploaded automatically once a test completes.

​
Before you begin

  • FlexLogger 2024 Q4 or above
  • API access set up with an API key and the REST and gRPC base URLs for your Sift environment
  • Optional: Set environment variables on the machine running FlexLogger to pre-fill plugin configuration fields

​
Set environment variables

Setting these Windows environment variables before adding either plugin to a FlexLogger project automatically populates the corresponding plugin settings, so you do not need to enter them manually in each plugin’s configuration dialog.

​
How the FlexLogger plugins work

Installing the Sift FlexLogger plugin package adds two ways to send data to Sift:
  • Stream Channel data to Sift live, as a test runs (Sift Stream)
  • Upload a TDMS file to Sift once a run stops (Sift TDMS Uploader)

​
Install the Sift FlexLogger plugins

  1. Go to the sift-labview Releases page and find the most recent release tagged flexlogger-plugins. Download flexlogger_dist.zip from that release.
  2. Unzip the file.
  3. Run install_flexlogger_plugins.bat.

​
Stream live data to Sift

  1. In FlexLogger, configure the Channels you want to stream.
  2. Select Add channels > Plug-in > Sift Stream.
  3. Click the configure (gear) icon on the Sift Stream plugin.
  4. If you set the environment variables beforehand, the fields are pre-filled. Otherwise, fill out the plugin settings.

​
Upload a test file to Sift

  1. In FlexLogger, configure the Channels you want to log.
  2. Select Add channels > Plug-in > Sift TDMS Uploader.
  3. Click the configure (gear) icon on the Sift TDMS Uploader plugin.
  4. If you set the environment variables beforehand, the fields are pre-filled. Otherwise, fill out the plugin settings.
  5. Start and stop a run in FlexLogger. Stopping the run generates a TDMS file for that session, which the plugin uploads to Sift automatically as a Run, as long as the plugin is configured in that project.
    Run name: To change the Run name, edit the TDMS file name in FlexLogger’s Logging Specification tab.

​
Verify

To verify data was received, open Sift and navigate to the Asset you configured. A new Run should appear containing the streamed or uploaded data. If no data appears, check the plugin log files at C:\Users\Public\Documents\National Instruments\FlexLogger\Plugins\IOPlugins\Sift Stream for error details, and confirm that the API key, gRPC URL, and REST URL were entered correctly in the plugin settings.
