This document provides answers to some frequently asked questions.
- What information is in the filename?
- Each file name will have a string of numbers, for example:
dcm_account1234_impression_2016022601_20160225_234912_218211994.csv.gz
-
2016022601
is in YYYYMMDDHH
format. This is the UTC hour for
events in that file (hours are numbered 0 to 23).
-
20160225_234912
is in YYYYMMDD_HHMMSS
format.
This is the time the report was generated in local account time (DCM and unified) or
EST (DBM only).
-
218211994
is the file ID.
- How do I know when all files are delivered?
- For each day there are:
- 24 click files (hours 0-23).
- 24 impression files (hours 0-23).
- 1 activity file.
- 21 match tables.
Clients with custom configurations may have different numbers.
- What if I encounter duplicate files for the same date and hour?
- This can happen. When more than one file has the same date/hour stamp, use the one with the
latest minutes / seconds, based on the filename timestamp.
- I think some of my data is incorrect, what can I do?
- Contact your support representative with information about the problem. If data
seems to be missing, provide details about which hours are missing, and files that aren’t
accounted for.
- How do I find out what's been deprecated in v2, or moved to match tables?
- See the migration guide
for information on mapping from v1 to v2.
