Yandex Cloud Functions

Viewing the execution log

    Function execution logs are stored for 14 days. The log uses Coordinated Universal Time, UTC.

    1. Select Cloud Functions in management console.
    2. Click the function you want to view the execution log for.
    3. In the window that opens, go to Logs and specify the time period. The default time period is 1 hour.

    When viewing the log, you can set a specific interval using the --since and --until flags. If no interval is specified when invoking a function, information for the last hour is displayed.

    The following flags are used:

    • --since: Time N and later.

    • --until: Time N and earlier.

    If you only specify one flag, information is displayed for the hour before or after N depending on the flag.

    Allowed time formats:

    • HH:MM:SS. Example: 15:04:05.

    • RFC-3339. Example: 2006-01-02T15:04:05Z, 2h, 3h30m ago.

    If you don't have the Yandex.Cloud command line interface yet, install and initialize it.

    The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

    To access a function, use its name or unique ID. To find them, get a list of functions in a folder.

    View the function execution log:

    $ yc serverless function logs <function name>
