Dynatrace api v2, how to access host's schemaId (builtin:anomaly-detection.infrastructure-disk) using setting/object REST API

The information is accessible thru the UI and not thru the API

Hi,

Easier way would be, going to schema in the UI:

Select "..." -> API:

As you can see there, it is not HOST-id, you need object ID. If you go to full API specification:

I would call all objects you are interested using filters (filtering by schema for example), get objects IDs, and make a second call to get details of ID (disk).

Best regards

Hello,

Here are the results of my REST explorations

Evironment:

tenants:
- 18
total Hosts:
- 45k
SchemaId to check:
- builtin:anomaly-detection.infrastructure-disks.per-disk-override
  - required to check that it's not been disabled accidentally

Cynematics:

get hosts (18 multipage request)
for each host:
- get /api/v2/entities/HOST-XXXXXXXXXXXXXXXX
- from each host get: (tens of disks per hosts)
  - "toRelationships": {
    "isDiskOf": [
    {
    "id": "DISK-XXXXXXXXXXXXXXXX",
    "type": "DISK"
    },
    ...
    ]
    }
  - for each disk:
    - get /api/v2/settings/objects?schemaIds=builtin%3Aanomaly-detection.infrastructure-disks.per-disk-override&scopes=DISK-XXXXXXXXXXXXXXXX&fields=objectId%2Cvalue

Conclusion:

Estimated number of REST request on the schemaId: 45000 times ( average of 10 disks per hosts configured) is 450k
About 20 hours to get the informations at 10 millisec per request.
- Tools used:
  - python 3.11
  - asyncio

This should be available at the HOST level just like the UI is offering, as it's not practical to use the UI to check 45k hosts
