Summary
- Type - Device Summary - summary of each device per day
- Granularity - DAY
- Dimensions -
period, did & channel - Computation Level - Level 1 (computed from raw telemetry)
- Frequency - Runs Daily
Purpose
Purpose of Device Summarizer to compute device level daily summary.
- Raw Telemetry: SEARCH & INTERACT events
- ME_WORKFLOW_SUMMARY

Algorithm Design
Field | Computation | Remarks |
|---|
did | context.did |
|
period | Integer value of the DAY |
|
total_ts | Sum (edata.eks.time_spent of all the ME_WORKFLOW_SUMMARY events) |
|
context.date_range.from(first_access) | context.date_range.from of first ME_WORKFLOW_SUMMARY event
|
|
context.date_range.to(last_access) | context.date_range.to of last ME_WORKFLOW_SUMMARY event
|
|
total_launches | Count of ME_WORKFLOW_SUMMARY events with dimensions.type = app |
|
contents_played | Count of ME_WORKFLOW_SUMMARY events with dimensions.type = content and dimensions.mode = play |
|
unique_contents_played | Count of unique object.id from content play ME_WORKFLOW_SUMMARY events |
|
dial_stats.total_count | Count of SEARCH events where edata.filters.dialcodes exists |
|
dial_stats.success_count | Count of SEARCH events where edata.filters.dialcodes exists and edata.size > 0 |
|
dial_stats.failed_count | Count of SEARCH events where edata.filters.dialcodes exists and edata.size = 0 |
|
content_downloads | Count of INTERACT events with edata.subType = "ContentDownload-Success" | For portal, it will be 0 |
