get-log-group-fields

Description

Returns a list of the fields that are included in log events in the specified log group, along with the percentage of log events that contain each field. The search is limited to a time period that you specify.

In the results, fields that start with @ are fields generated by CloudWatch Logs. For example, @timestamp is the timestamp of each log event.

The response results are sorted by the frequency percentage, starting with the highest percentage.

Synopsis

  get-log-group-fields
--log-group-name <value>
[--time <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--log-group-name (string)

The name of the log group to search.

--time (long)

The time to set as the center of the query. If you specify time , the 8 minutes before and 8 minutes after this time are searched. If you omit time , the past 15 minutes are queried.

The time value is specified as epoch time, the number of seconds since January 1, 1970, 00:00:00 UTC.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.
