Adding data

There are a couple ways to add data to a dataset;
  • Manually: You can add data on a per message basis.
  • From traces: You can fill the dataset by selecting a group of messages already captured.
  • CSV Upload: You can fill the dataset by uploading a CSV file.
  • Continuously populate: You can continuously populate the dataset with data traced from production.

​
Manually

To add data manually, click the “Add to Dataset” button on the messages page after selecting a message. You will then be able to choose the dataset type and preview the data that will be added.

CSV Upload

To add data by CSV upload, go to your datasets page and select the dataset you want to update. Click the “Upload CSV” button and upload your CSV or JSONL file. You can then map the columns from your file to the appropriate fields in the dataset based on the dataset type.
