Setting Custom Log Time

You can enable Custom Log Time to display the custom log time on the Log Search tab page. If Custom Log Time is disabled, the log collection time is displayed as the log time on this tab page.

Enabling Custom Log Time

  1. Log in to the LTS console. The Log Management page is displayed by default.
  2. Click the target log group or log stream to access the log stream details page.
  3. On the Log Search tab page, click Log Settings in the upper right corner. On the displayed page, click the Cloud Structuring Parsing tab. For details, see Setting Cloud Structuring Parsing.
  4. After cloud structuring parsing is configured, enable Custom Log Time and specify the following parameters.

    A time deviation may occur around the time displayed on the log search page when you enable or disable Custom Log Time. Do not frequently enable or disable it.
