Exposes an API to fetch records stored in Grail

@dynatrace-sdk/client-query

v1.18.1

npm install @dynatrace-sdk/client-query

queryAssistanceClient

import { queryAssistanceClient } from '@dynatrace-sdk/client-query';

queryAutocomplete

queryAssistanceClient.queryAutocomplete(config): Promise<AutocompleteResponse>

Get a structured list of suggestions for the query at the given position.

For information about the required permissions see the Bucket and table permissions in Grail documentation.

Overview

We provide a list of suggestions that may be used after the cursor position. The following queries will all provide the same results:

• query: "f"
• query: "f", cursorPosition:1
• query: "fetch ", cursorPosition:1

Available fields:

Field	Description
suggestions	a list of suggestions. Each item is a separate possible suggestion, despite they might have the same outputs.
optional	whether the suggestion is optional. If true, the query until the cursor position might work. If false, the query is definitely incomplete or invalid if cut at the cursor position.

Fields in the suggestions

Field	Description
suggestion	a string representing the whole suggestion. This information could also be derived from the parts.
alreadyTypedCharacters	how many characters of this suggestion have already been typed (and will be overridden by the suggestion).
parts	a list of semantically enriched information on what are the parts of a suggestion.

Fields in parts

Field	Description
suggestion	a string representing the current part of the suggestion.
type	current types: SPACE, PIPE, COMMAND (may be extended)

The type helps to treat specific parts of the suggestion different to others; either by a different visualization, a link to docs, etc.

Parameters

Name	Type
config.body*required	AutocompleteRequest

Returns

Return type	Description
Promise<AutocompleteResponse>	A list of structured autocomplete suggestions.

Throws

Error Type	Error Message
ErrorEnvelopeError	The supplied request is wrong. Either the query itself or other parameters are wrong. | An internal server error has occurred.

Code example

import { queryAssistanceClient } from "@dynatrace-sdk/client-query";

const data = await queryAssistanceClient.queryAutocomplete({
  body: {
    query:
      'fetch events | filter event.type == "davis" AND davis.status != "CLOSED" | fields timestamp, davis.title, davis.underMaintenance, davis.status | sort timestamp | limit 10',
  },
});

queryParse

queryAssistanceClient.queryParse(config): Promise<DQLNode>

Get a structured tree of the canonical form of the query.

For information about the required permissions see the Bucket and table permissions in Grail documentation.

Overview

Returns the parsed query as a tree, containing the structure of the canonical query. Tree-nodes can contain references to the token position where they originate from. This may help to provide hover effects, show canonical forms, mark optional items, and more.

Details

The query tree consists of nodes that contain different additional information (everything optional):

General Fields

Field	Mandatory	Description
tokenPosition	no	optional. If present, it represents the position within the query string where the node refers to.
isOptional	no	whether this node could be left out and the result would still be the same query (semantically).

tokenPosition

contains start (inclusive) and end (inclusive), both contain index (0 based; fur substrings), line and column (both 1-based; for readability).

• If tokenPosition is present, it always contains start and end with all fields
• If tokenPosition is not present, there might still be nested nodes that do contain a position
• If start == end, the position refers to a single character
• If start > end, we know for sure that something was inserted.

We can always check whether the canonical representation of a node matches the text in the tokenPosition to see whether something was inserted, removed, or changed.

isOptional

only present if it is true.

Optional nodes can e.g. be optional braces that make a query more readable, but are not necessary. This could be used to enter ghost braces and implicit functions in the user's input field; maybe with different formatting (using the tokenPosition of sibling nodes we can also check whether the user wrote these or not).

Advanced Token Types

each node is of one of following types and may contain more fields:

• Terminal Node
• ContainerNode
• Alternative Node

Terminal Node

can be identified by checking whether canonicalString is present

Field	Mandatory	Description
type	yes	the type of the terminal node - do not confuse with the type of container nodes
canonicalString	yes	the canonical string representation. Concatenating the canonicalString of all nested terminal nodes provides the canonical form of the query.
isMandatoryOnUserOrder	no	may only be present if (type="BRACE_OPEN" or type="BRACE_CLOSE") and isOptional=true. For usage see section Special node type: PARAMETERS

Current types of terminal nodes (list might grow):

• SPACE
• LINEBREAK
• INDENT
• PIPE
• DOT
• COLON
• COMMA
• BRACE_OPEN
• BRACE_CLOSE
• BRACKET_OPEN
• BRACKET_CLOSE
• PARENTHESIS_OPEN
• PARENTHESIS_CLOSE
• QUOTE
• SLASH
• BOOLEAN_TRUE
• BOOLEAN_FALSE
• NULL
• COMMAND_NAME
• PARAMETER_KEY
• PARAMETER_VALUE_SCOPE
• FUNCTION_NAME
• OPERATOR
• TRAVERSAL_OPERATOR
• TRAVERSAL_RELATION_NAME
• TRAVERSAL_HOP_COUNT
• SIMPLE_IDENTIFIER
• NUMBER
• STRING
• TIME_UNIT
• TIMESTAMP_VALUE
• METRIC_KEY
• VARIABLE

ContainerNode

can be identified by checking whether children is present

Field	Mandatory	Description
type	yes	the type of the container node - do not confuse with the type of terminal nodes
children	yes	the children for the node. might be of any type

Current types of container nodes (list might grow):

• QUERY
• EXECUTION_BLOCK
• COMMAND
• COMMAND_SEPARATOR
• PARAMETER_WITH_KEY
• GROUP
• PARAMETERS - check examples further down
• PARAMETER_NAMING
• PARAMETER_SEPARATOR
• FUNCTION
• FUNCTION_PART - check examples further down
• EXPRESSION
• IDENTIFIER
• SOURCE_ID
• DURATION
• TIMESTAMP
• TIMEFRAME
• TRAVERSAL_PATH
• TRAVERSAL_STEP

Special node type: PARAMETERS

can contain children representing the parameters. Every second child is of type PARAMETER_SEPARATOR.

You may reorder the children based on their tokenPosition to get the user order. However, in this case, you need to consider isMandatoryOnUserOrder to determine whether the grouping braces are mandatory or not.

Example

For the query SORT a, {direction:"descending", b}, the canonical form is:

SORT a, {b, direction:"descending"}

This is the order, in which the parameters are returned in the query tree. Parameters are {a} and {{b} and {direction:"descending"}}. In this case, the braces are optional.

SORT a, {b, direction:"descending"} is equivalent to SORT a, b, direction:"descending"

However, if you reorder the children by tokenPosition, the braces are not optional, because

SORT a, direction:"descending", b is interpreted as SORT {a, direction:"descending"}, b

So, if the children in PARAMETERS are re-ordered by tokenPosition, braces (or in general: TerminalNodes) are only optional if isOptional && !isMandatoryOnUserOrder.

Special node type: FUNCTION_PART

A container node of type FUNCTION may contain nodes of type FUNCTION_PART.

If those FUNCTION_PARTs are marked as optional, this means you have to either include all or none of these optional function parts.

Example:

filter anyMatch(a.b == 1, input:a)

The optional function parts are anyMatch( and , input:a). If you leave out both, the command will still work: filter a.b == 1 and return the same result. Using one of these optional function parts and removing the other will lead to an invalid query.

Alternative Node

can be identified by checking whether alternatives is present

Field	Mandatory	Description
alternatives	yes	Type: Map<AlternativeType, DQLNode>

When displaying the query, pick one option. You may use the other options for hovering, replacing, and more.

Current values of AlternativeType (list might grow):

• CANONICAL: This node is the one we will use for our canonical form
• USER: An alternative that is also valid, but not canonical; and this version was picked by the user.
• INFO: only if the canonical version is not present

Examples:

• CANONICAL is not present, USER is present: user's nodes are optional, but not canonical (usually optional nodes are still canonical)
• CANONICAL is present, USER is not present: same as if the canonical node was optional. If this happens, it is likely that there is also an INFO node
• CANONICAL is present, USER is present: there are different alternatives
• INFO is present: usually if CANONICAL is not present (e.g. the parameter key for FILTER a == 1), there is an info node for FILTER condition:a == 1. This condition: was neither written by the user nor is it canonical; but it might be used to help the user understand what this parameter means.

Parameters

Name	Type
config.body*required	ParseRequest

Returns

Return type	Description
Promise<DQLNode>	A node containing more nodes, a node offering different (semantically equivalent) versions of the query parts, or a terminal node that shows the canonical form.

Throws

Error Type	Error Message
ErrorEnvelopeError	The supplied request is wrong. Either the query itself or other parameters are wrong. | An internal server error has occurred.

Code example

import { queryAssistanceClient } from "@dynatrace-sdk/client-query";

const data = await queryAssistanceClient.queryParse({
  body: {
    query:
      'fetch events | filter event.type == "davis" AND davis.status != "CLOSED" | fields timestamp, davis.title, davis.underMaintenance, davis.status | sort timestamp | limit 10',
  },
});

queryVerify

queryAssistanceClient.queryVerify(config): Promise<VerifyResponse>

Verifies a query without executing it.

For information about the required permissions see the Bucket and table permissions in Grail documentation.

Overview

Verifies the supplied query string and other query parameters for lack of any errors, but without actually submitting the query for execution.

Parameters

Name	Type
config.body*required	VerifyRequest

Returns

Return type	Description
Promise<VerifyResponse>	Supplied query and parameters were verified.

Throws

Error Type	Error Message
ErrorEnvelopeError	The supplied request is wrong. | An internal server error has occurred.

Code example

import { queryAssistanceClient } from "@dynatrace-sdk/client-query";

const data = await queryAssistanceClient.queryVerify({
  body: {
    query:
      'fetch events | filter event.type == "davis" AND davis.status != "CLOSED" | fields timestamp, davis.title, davis.underMaintenance, davis.status | sort timestamp | limit 10',
  },
});

queryExecutionClient

import { queryExecutionClient } from '@dynatrace-sdk/client-query';

queryCancel

queryExecutionClient.queryCancel(config): Promise<void | QueryPollResponse>

Cancels the query and returns the result if the query was already finished, otherwise discards it.

For information about the required permissions see the Bucket and table permissions in Grail documentation.

Overview:

Cancels a running Grail query and returns a list of records if the query already finished.

The response format:

If the query was already finished, a response body including the result will be returned. Otherwise the response will contain no body.

The result has three main sections:

• the 'records' section contains the individual records, where each record consists of a set of fields and their corresponding values.
• the 'types' section describes the corresponding data types that a record field has.
• the 'metadata' section contains information about the query like 'analysisTimeframe', 'timezone' or 'locale'.

Every record has an implicit 'index' according to the position in the 'records' JSON array. The types section has a list of 1..N possible type 'buckets'. Each such bucket has an 'indexRange' which indicates which records will find their field types in which bucket. The index range has two values start & end and can be thought of as [startIndex, endIndex).

A field part of a record with index 'i' will find its corresponding field type by first locating the bucket that satisfies:

startIndex <= i <= endIndex

Once the bucket is found the 'mappings' object has an entry for all the fields that are part of that record with index 'i'.

Since enforcement of a particular schema is absent at ingestion time, it is possible to have records that share the same field name but their values are of a different type. This phenomenon will hence forth be named as a "collision". When a collision does occur, we will create a new type 'bucket' that will have a different index range where the new record field types will be placed. It is guaranteed that every field of every record will have a corresponding type. Clients should always take the included types into account when consuming records!

Parameters

Name	Type	Description
config.enrich	string	If set additional data will be available in the metadata section.
config.requestToken*required	string	The request-token of the query.

Returns

Return type	Description
Promise<QueryPollResponse	void>

Throws

Error Type	Error Message
ErrorEnvelopeError	The supplied request is wrong. Either the query itself or other parameters are wrong. | An internal server error has occurred.

Code example

import { queryExecutionClient } from "@dynatrace-sdk/client-query";

const data = await queryExecutionClient.queryCancel({
  requestToken: "...",
});

queryExecute

queryExecutionClient.queryExecute(config): Promise<QueryStartResponse>

Starts a Grail query.

For information about the required permissions see the Bucket and table permissions in Grail documentation.

Overview:

Executes a query and returns a list of records.

For details about the query language see the Dynatrace Query Language documentation.

The response format:

The json response will contain the state of the started query. If the query succeeded, the result will be included. Otherwise the response will contain a request token to reference the query in future polling requests.

The result has two main sections:

• The 'records' section contains the individual records, where each record consists of a set of fields and their corresponding values.
• The 'types' section describes the corresponding data types that a record field has.

Every record has an implicit 'index' according to the position in the 'records' JSON array. The types section has a list of 1..N possible type 'buckets'. Each such bucket has an 'indexRange' which indicates which records will find their field types in which bucket. The index range has two values start & end and can be thought of as [startIndex, endIndex).
