Add loop task to enable or disable host monitoring

Smalhotra89 — Mon, 15 Dec 2025 12:14:31 GMT

Hi team,

I want to use loop task for a list of hosts to enable or disable monitoring in Dynatrace. I would like to have multiple hosts to be executed with single workflow for http_request.

[ { "externalId": "string", "schemaId": "builtin:host.monitoring", "schemaVersion":"1.4", "scope": "HOST-7AA30C2D50D93E12", "value": { "enabled": false } } ]

Hi @Smalhotra89

Yes this is possible with the loop task. Before you start you need to generate an "Access Token" with the scopes "Read settings" and "Write settings".

Then you can start creating the workflow. First you need to fetch all settings objects for the list of hosts you want to disable or enable with a http request task. The list of hosts is put in the URL and is comma separated. In the header section you add the Autorization details, please have a look at following screenshot

in the subsequent http request task you need to configure the loop task like this

The input for the tasks should be that

For this approach you have to create the token and manage it yourself.

But you could also do the same thing with a javascript task with custom javascript code, the benefit there would be that you don't need to create a token for changing the settings. Since the used sdks underneath managed this for you.

this is the snippet for the javascript task

// optional import of sdk modules import { execution } from '@dynatrace-sdk/automation-utils'; import { actionExecution } from "@dynatrace-sdk/automation-utils"; import { SettingsObject, settingsObjectsClient } from "@dynatrace-sdk/client-classic-environment-v2"; export default async function ({ execution_id, action_execution_id }) { // your code goes here // e.g. get the current execution const ex = await execution(execution_id); const actionEx = await actionExecution(action_execution_id); const scopes = actionEx.loopItem["host"]; //console.log(scopes); const settingsObjects = await settingsObjectsClient.getSettingsObjects({ schemaIds: "builtin:host.monitoring", scopes, fields: "objectId,value,summary,searchSummary,created,modifid,createdBy,modifiedBy,author,updateToken,scope,modificationInfo,schemaId,schemaVersion,externalId" }); //console.log(settingsObjects); if (settingsObjects.items.length > 0){ const settingsObject = (settingsObjects.items[0]); const settingsObjectResponse = await settingsObjectsClient.putSettingsObjectByObjectId({ objectId: settingsObject.objectId, body: { updateToken: settingsObject.updateToken, value: { "enabled": false } } }); return { settingsObjectResponse }; } }

Best,
Sini

Thanks Sini, javascript task works well.

I was unable to use the http request with loop task as it was unable to read allobjects.json.item in loop. I am not sure if I did something wrong but the first task to get all objects task ran through fine.

How do I iterate through all values from a fetch query using javascript?

this worked for me and disabled monitoring on all hosts

Hi @vs185250 ,@Smalhotra89

I hope you guys are doing well.

I have replicated the above use case in my environment and it is not getting executed and requesting your help here.

Do I have to pass any bearer token ?

Thanks

Hi @DineshP,

In this case you have to use API token instead Bearer Token.

The APIs using in this workflow requeries API token.

Hope it helps.

Regards,

Elena.

Hi,

You have to use this header:

headers: {
'Accept': 'application/json; charset=utf-8',
'Authorization': 'Api-Token dt0c01.XXXXXXXXXXXXXXXXX'
}

like in this screenshot

Hope it helps.

I have the same ask, can someone upload a workflow that uses javascript or api method to enable or disable hosts that belong to a certain host group?

Batch file for now:

@echo off
setlocal ENABLEDELAYEDEXPANSION

REM ==== Config ====
set DT_ENV_URL=https://{environmentid}.live.dynatrace.com
set DT_API_TOKEN=dt0c01.YOURLONGA$$TOKENNAME
if "%DT_API_TOKEN%"=="" (
echo ERROR: Please set DT_API_TOKEN environment variable.
exit /b 1
)

set ENDPOINT=%DT_ENV_URL%/api/v2/settings/objects

REM ==== Host list ====

REM ++++Exported List from Dynatrace Infrastructure and Operations App++++

set HOSTS= ^
HOST-xxxaaa ^
HOST-xxxfffff ^
HOST-xxxddd ^
HOST-xxx

for %%H in (%HOSTS%) do (

echo Posting for %%H ...

set PAYLOAD=[{""schemaId"":""builtin:host.monitoring"",""schemaVersion"":""1.4"",""scope"":""%%H"",""value"":{""enabled"":false}}]

curl -s -X POST ^

-H "Accept: application/json; charset=utf-8" ^

-H "Content-Type: application/json; charset=utf-8" ^

-H "Authorization: Api-Token %DT_API_TOKEN%" ^

-d "!PAYLOAD!" ^

echo.

)
