This topic describes how to set the time format for Logtail Configs and the precautions you need be aware of first.

  • The minimum granularity that you can configure for timestamps in Log Service is seconds.

  • In the time field, only the front part that contributes to time parsing is required.

The following shows a setting example:
Custom1 2017-12-11 15:05:07
%Y-%m-%d %H:%M:%S
Custom2 [2017-12-11 15:05:07.012]
