[Unlock Workflow Power] only with one Running.JS scheduled Task

uros_djukic1 — Mon, 22 Jul 2024 14:39:45 GMT

In our customer context, we used the Workflow to collect the availability rate on a specific scenario in a solution composed of external APIs. In order to feed the main dashboard of availability of "critical" applications. Thus meeting a functional need.

Valid and compliant for Dynatrace SaaS platform version 1.296.

*** client context

Formerly we had to use a Python script and implement a V1 extension, here the simple use of the Workflow with a little knowledge via Javascript makes our work easier!

*** WORKAROUND OVERVIEW

Before sharing my "only one Task JS" please find main lines of my running.JS :

1 . // Retrieve credentials from the credential vault for External API
2. // fetching bearer Token value
3. // collect APIs parameters from external endpoints
4 . // ingest metric to Dynatrace

Find my script lightened but with the important steps, all-in-one running.JS task as depicted below :

import { credentialVaultClient } from "@dynatrace-sdk/client-classic-environment-v2";

import { executionsClient } from '@dynatrace-sdk/client-automation';

import { execution } from '@dynatrace-sdk/automation-utils';

import { metricsClient } from "@dynatrace-sdk/client-classic-environment-v2";

// Main()

export default async function ({ execution_id }) { ==> Main function

try {

// Retrieve credentials from the credential vault for External endpoint API

const External endpointCredentials = await credentialVaultClient.getCredentialsDetails(

{ id: "CREDENTIALS_VAULT-XXX" }

);

const External endpointUsername = External endpointCredentials.username;

const External endpointPassword = External endpointCredentials.password;

if (!External endpointUsername || !External endpointPassword) {

throw new Error('External endpoint credentials are not defined.');

}

// fetching bearer Token value

async function fetchBearerToken() { ==> function 1 : getToken from External endpoint

try {

const response = await fetch('https://api.External endpoint.XXX/auth/login', {

method: 'POST',

body: JSON.stringify({ email: External endpointUsername, password: External endpointPassword }),

headers: {

'Content-Type': 'application/json',

'Accept': 'application/json',

});

// Parse response body as JSON

}

// collect APIs parameters from External endpoint

async function fetchData(bearerToken) { ==> function 2 : get parameters/data from External endpoint (i.e. scenarioName)

try {

console.log('Bearer Token:', bearerToken);

// make dates dynamic

function formatDate(date) {

var d = new Date(date),

month = '' + (d.getMonth() + 1),

day = '' + d.getDate(),

year = d.getFullYear();

if (month.length < 2)

month = '0' + month;

if (day.length < 2)

day = '0' + day;

return [year, month, day].join('-');

};

var today = new Date();

var firstDay = new Date(today.getFullYear(),today.getMonth()-1,1);

firstDay.setDate(Math.min(today.getDate(),firstDay.getDate()));

var lastDay = formatDate(new Date(today.getFullYear(),today.getMonth(),0))+ ' 00:00:00';

firstDay=formatDate(firstDay.getFullYear()+'-'+(firstDay.getMonth()+1)+'-'+firstDay.getDate())+ ' 00:00:00';

console.log(firstDay);

console.log(lastDay);

const body = {

"dates": {

"from": firstDay,

"to": lastDay

}

};

// Define the endpoint to fetch data from

const apiEndpoint = 'https://api.External endpoint.XXX.net/results/avail/XXX'; // Replace with the actual endpoint

// Try to parse response as JSON if needed

}

// Fetch bearer token and data

const bearerToken = await fetchBearerToken();

const scenarioData = await fetchData(bearerToken);

// Assuming the scenarioData contains the relevant fields directly

const get_scenario_name = scenarioData.scenarioName;

const get_scenario_rate = scenarioData.ratePercent;

// Send the metrics to Dynatrace ==> Ingest metrics via Dynatrace API

const environment = "/platform/classic/environment-api/v2/metrics/ingest";

try {

const response = await fetch(environment, {

method: 'POST',

headers: {

'Content-Type': 'text/plain; charset=utf-8',

body: `External endpoint.availability.rate,scenario.name=${get_scenario_name} ${get_scenario_rate}`,

});

// Try to parse response as JSON if needed

} catch (error) {

console.error('Error in script execution:', error);

throw error;

}

I hope it helps,

Thanks
