Example:

logs.QueryDefinition(self, "QueryDefinition",
    query_definition_name="MyQuery",
    query_string=logs.QueryString(
        fields=["@timestamp", "@message"],
        parse_statements=["@message "[*] *" as loggingType, loggingMessage", "@message "<*>: *" as differentLoggingType, differentLoggingMessage"
        ],
        filter_statements=["loggingType = "ERROR"", "loggingMessage = "A very strange error occurred!""
        ],
        sort="@timestamp desc",
        limit=20
    )
)
Parameters:

  • display (Optional[str]) – Specifies which fields to display in the query results. Default: - no display in QueryString

  • fields (Optional[Sequence[str]]) – Retrieves the specified fields from log events for display. Default: - no fields in QueryString

  • filter (Optional[str]) – (deprecated) A single statement for filtering the results of a query based on a boolean expression. Default: - no filter in QueryString

  • filter_statements (Optional[Sequence[str]]) – An array of one or more statements for filtering the results of a query based on a boolean expression. Each provided statement generates a separate filter line in the query string. Note: If provided, this property overrides any value provided for the filter property.

  • limit (Union[int, float, None]) – Specifies the number of log events returned by the query. Default: - no limit in QueryString

  • parse (Optional[str]) – (deprecated) A single statement for parsing data from a log field and creating ephemeral fields that can be processed further in the query. Default: - no parse in QueryString

  • parse_statements (Optional[Sequence[str]]) – An array of one or more statements for parsing data from a log field and creating ephemeral fields that can be processed further in the query. Each provided statement generates a separate parse line in the query string. Note: If provided, this property overrides any value provided for the parse property. Default: - no parse in QueryString

  • sort (Optional[str]) – Sorts the retrieved log events. Default: - no sort in QueryString
