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

[hyperdev]

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

https://<tenant>/.../ui/settings/HOST-xxxxxxxxxxxxxxxx/builtin:anomaly-detection.infrastructure-disks?gtf=-2h&gf=all

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
