Find the structure of text messages.

--messages string[] required

The list of messages you want to analyze.

--column-names string

If the format is delimited, you can specify the column names in a comma-separated list. If this parameter is not specified, the structure finder uses the column names from the header row of the text. If the text does not have a header role, columns are named "column1", "column2", "column3", for example.

Repeatable: pass --column-names multiple times to supply more than one value

--delimiter string

If you the format is delimited, you can specify the character used to delimit the values in each row. Only a single character is supported; the delimiter cannot have multiple characters. By default, the API considers the following possibilities: comma, tab, semi-colon, and pipe (|). In this default scenario, all rows must have the same number of fields for the delimited format to be detected. If you specify a delimiter, up to 10% of the rows can have a different number of columns than the first row.

--ecs-compatibility string

The mode of compatibility with ECS compliant Grok patterns. Use this parameter to specify whether to use ECS Grok patterns instead of legacy ones when the structure finder creates a Grok pattern. This setting primarily has an impact when a whole message Grok pattern such as %{CATALINALOG} matches the input. If the structure finder identifies a common structure but has no idea of meaning then generic field names such as path, ipaddress, field1, and field2 are used in the grok_pattern output, with the intention that a user who knows the meanings rename these fields before using it.

--[no-]explain

If this parameter is set to true, the response includes a field named explanation, which is an array of strings that indicate how the structure finder produced its result.

--format string

The high level structure of the text. By default, the API chooses the format. In this default scenario, all rows must have the same number of fields for a delimited format to be detected. If the format is delimited and the delimiter is not set, however, the API tolerates up to 5% of rows that have a different number of columns than the first row.

--grok-pattern string

If the format is semi_structured_text, you can specify a Grok pattern that is used to extract fields from every message in the text. The name of the timestamp field in the Grok pattern must match what is specified in the timestamp_field parameter. If that parameter is not specified, the name of the timestamp field in the Grok pattern must match "timestamp". If grok_pattern is not specified, the structure finder creates a Grok pattern.

--quote string

If the format is delimited, you can specify the character used to quote the values in each row if they contain newlines or the delimiter character. Only a single character is supported. If this parameter is not specified, the default value is a double quote ("). If your delimited text format does not use quoting, a workaround is to set this argument to a character that does not appear anywhere in the sample.

--[no-]should-trim-fields

If the format is delimited, you can specify whether values between delimiters should have whitespace trimmed from them. If this parameter is not specified and the delimiter is pipe (|), the default value is true. Otherwise, the default value is false.

--[no-]should-parse-recursively

If the format is ndjson, you can specify whether to parse nested JSON objects recursively. The nested objects are parsed to a maximum depth equal to the default value of the index.mapping.depth.limit setting. Anything beyond that depth is parsed as an object type field. For formats other than ndjson, this parameter is ignored.

--timeout string

The maximum amount of time that the structure analysis can take. If the analysis is still running when the timeout expires, it will be stopped.

--timestamp-field string

The name of the field that contains the primary timestamp of each record in the text. In particular, if the text was ingested into an index, this is the field that would be used to populate the @timestamp field. If the format is semi_structured_text, this field must match the name of the appropriate extraction in the grok_pattern. Therefore, for semi-structured text, it is best not to specify this parameter unless grok_pattern is also specified. For structured text, if you specify this parameter, the field must exist within the text. If this parameter is not specified, the structure finder makes a decision about which field (if any) is the primary timestamp field. For structured text, it is not compulsory to have a timestamp in the text.

--timestamp-format string

The Java time format of the timestamp field in the text. Only a subset of Java time format letter groups are supported: * a * d * dd * EEE * EEEE * H * HH * h * M * MM * MMM * MMMM * mm * ss * XX * XXX * yy * yyyy * zzz Additionally S letter groups (fractional seconds) of length one to nine are supported providing they occur after ss and are separated from the ss by a period (.), comma (,), or colon (:). Spacing and punctuation is also permitted with the exception a question mark (?), newline, and carriage return, together with literal text enclosed in single quotes. For example, MM/dd HH.mm.ss,SSSSSS 'in' yyyy is a valid override format. One valuable use case for this parameter is when the format is semi-structured text, there are multiple timestamp formats in the text, and you know which format corresponds to the primary timestamp, but you do not want to specify the full grok_pattern. Another is when the timestamp format is one that the structure finder does not consider by default. If this parameter is not specified, the structure finder chooses the best format from a built-in set. If the special value null is specified, the structure finder will not look for a primary timestamp in the text. When the format is semi-structured text, this will result in the structure finder treating the text as single-line messages.

--input-file string

path to a JSON file to use as command input

-V --[no-]version

Print the Elastic CLI version

--config-file string

path to a config file (default: ~/.elasticrc.yml)

--use-context string

override the active context from the config file

--command-profile string

restrict available commands to a deployment profile (serverless, stack, default)

--[no-]json

output as JSON

--output-fields string

comma-separated list of fields to include in output (dot-notation supported)

--output-template string

Mustache-like template for custom text output (e.g. "{{id}}: {{name}}")

--[no-]dry-run

validate all inputs and exit without performing any action (preview changes without applying them)
