Hi @Felix Müller ,
Apologies for the delayes response. Pleae find below the answer to your question:
Unfortunately, setting the "Availability Cloud role name/instance" fields for availability tests are not available currently. Both “cloud_RoleInstance” and “cloud_RoleName” are common fields to all tables in Application Insights workspace (e.g. “requests”, “dependencies”). Availability Tests currently do not populate those fields. Also, it not sure how it would help even if they were populated (as those values would correspond to the cluster instances where availability tests are run from within Microsoft datacenters).
Regarding "correlating with other entities", it is done via "operationId" to correlate various telemetry (for example, requests). Please refer: Azure Application Insights telemetry correlation - Azure Monitor | Microsoft Learn The results obtained from AvailabilityTest would not fit in this context, as they would not be part of such operation/transaction.
Please let us know if you have any questions.
Please 'Accept as answer' and ‘Upvote’ if it helped so that it can help others in the community looking for help on similar topics.
