analyzersClient

import { analyzersClient } from '@dynatrace-sdk/client-davis-analyzers';

cancelAnalyzerExecution

Stop a started analyzer execution.

Required scope: davis:analyzers:execute

Use the request token that was returned when starting an analyzer execution to cancel it.

Parameters

| Name | Type | Description | | --- | --- | --- | |config.analyzerName*required|string|The name of the analyzer. | |config.requestToken*required|string|The request token is returned when starting a long-running analyzer execution. It can be used to do follow-up operations like polling and cancelling. |

Returns

The current analyzer execution status and an optional partial result.

import { analyzersClient } from "@dynatrace-sdk/client-davis-analyzers";

const data = await analyzersClient.cancelAnalyzerExecution({
  analyzerName: "...",
  requestToken: "RHluYXRyYWNlMjAyMw==",
});

executeAnalyzer

Asynchronously execute an analyzer with the given input.

Required scope: davis:analyzers:execute

The analyzer execution is started asynchronously. If the result is not available after a short time (in the order of 1-2 seconds), a request token is returned to poll for the result. Otherwise, the final result is directly available and no request token is returned.

Depending on the chosen analyzer and the analyzer input, additional scopes might be required, e.g. storage:buckets:read and storage:metrics:read to enable the analyzer to read time series data from Grail™.

Parameters

| Name | Type | Description | | --- | --- | --- | |config.analyzerName*required|string|The name of the analyzer. | |config.body*required|AnalyzerInput| |

Returns

The final analyzer result and execution status. | The current analyzer execution status and a request token and time-to-live (TTL) to continue polling the result with.

import { analyzersClient } from "@dynatrace-sdk/client-davis-analyzers";

const data = await analyzersClient.executeAnalyzer({
  analyzerName: "...",
  body: {
    timeSeriesData: {
      expression: "timeseries avg(dt.host.cpu.usage)",
    },
    forecastHorizon: 10,
  },
});

getAnalyzerDocumentation

Get the documentation for an analyzer.

Required scope: davis:analyzers:read

pollAnalyzerExecution

Poll for the result of a started analyzer execution.

Required scope: davis:analyzers:execute

Use the request token returned when starting an analyzer execution to poll for a result.

The executionStatus of the result indicates if the analyzer execution is already completed. While the status is RUNNING, wait and poll for the result again in subsequent calls.

Parameters

queryAnalyzers

Query all available analyzer definitions.

• The output definition specifies how the returned analyzer result is structured.

Parameters

| Name | Type | Description | | --- | --- | --- | |config.addFields|string|Specify which meta-information to fetch in addition to the default fields name, displayName and description.

When using the operators =and !=, filtering is case sensitive. The following operators are supported: = != contains starts-with ends-with and or Parenthesis and the not operator are currently not supported. The following fields are valid filtering parameters: baseAnalyzer description displayName labels name type Any other field will result in a HTTP 400 response. | |config.pageKey|string|The cursor for the page of results. Find it in the nextPageKey field of the previous response. If the page-key parameter is used, no other query parameters must be provided. If not provided, the first page is always returned. | |config.pageSize|number|The amount of returned analyzer definitions in a single response payload. By default, 50 is used. The maximum is 200. |
