@dynatrace-sdk/client-davis-analyzers
v1.6.0
npm install @dynatrace-sdk/client-davis-analyzers

analyzersClient​

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

cancelAnalyzerExecution​

analyzersClient.cancelAnalyzerExecution(config): Promise<void | AnalyzerExecuteResult>

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​

NameTypeDescription
config.analyzerName*requiredstringThe name of the analyzer.
config.requestToken*requiredstring

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.

Code example

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

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

executeAnalyzer​

analyzersClient.executeAnalyzer(config): Promise<AnalyzerExecuteResult>

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​

NameTypeDescription
config.analyzerName*requiredstringThe name of the analyzer.
config.body*requiredAnalyzerInput

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.

Code example

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,
  },
});

getAnalyzer​

analyzersClient.getAnalyzer(config): Promise<AnalyzerDefinitionDetails>

getAnalyzerDocumentation​

analyzersClient.getAnalyzerDocumentation(config): Promise<Binary>

pollAnalyzerExecution​

analyzersClient.pollAnalyzerExecution(config): Promise<AnalyzerExecuteResult>

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​
