2. The Activity Log

Double click on the activity log will open the logs details

Reading the log and understanding it:

The logs have 2 different Tabs:

1. Main Details - Will provide an overview of the surveyors/interviews/Attachments collected on the device.

The Main Details screen is split to 2 sections:

1.1. Summary - Summarizes the total interviews per Survey/Surveyor that were conducted on the device, including a breakdown of how many were Uploaded/Canceled/Deleted/StillOnDevice.

1.2. Log - Will list more information on each Interview - such as: If the subject was Test or Deleted, DeviceIndex, Attachment Information etc. 

2. Raw Data - Will provide step by step activities actions on the device for each interview, for example: We can see that DeviceIndex - D1508066-11 started at 31/01/2017 08:41:41AM and then cancelled manually on 31/01/2017 09:01:43 and you can see on the right in the comment column in which question it was canceled. 

Please Note: As in other SurveyToGo Grids both in the 'Main Details' and the 'Raw Data' you can drag and drop the fields to filter the results showing.
