API to pull all host group ID's

lee_rovner — Wed, 21 Aug 2024 08:28:36 GMT

I am trying to pull in ALL my hostgroup ID's from the DT API.

It used to work using

https:// xxxxxlive.dynatrace.com/api/v1/entity/infrastructure/hosts?tag=ds%3Aprod&showMonitoringCandidates=false&includeDetails=true

now, I am getting blank hostGroups

You can try using the Monitored Entities API, using the entity type HOST_GROUP should give you what you are looking for:

/api/v2/entities?entitySelector=type%28%22host_group%22%29

Hi Axel,

There appears to be a bug in this API, when issuing a nextPageKey parameter is throws an exception

{ "error": { "code": 400, "message": "Constraints violated.", "constraintViolations": [ { "path": "entitySelector", "message": "must not be used in combination with nextPageKey query parameter.", "parameterLocation": "QUERY", "location": null }, { "path": "pageSize", "message": "must not be used in combination with nextPageKey query parameter.", "parameterLocation": "QUERY", "location": null } ] } }

You must remove ALL parameters before using the nextPageKey or you will get the errors you show here.

This is very useful information and I was able to get the list of host groups using the API. The only question I have is how do I associate these host_groups to the hosts themselves? I don't see a shared host Id/host group id, or at least know how to properly format the URL to pull both information together to allow me to view what host groups are associated to a given host.

I dont think the Host group monitored API information gives you that, unfortunately you would need a second call for hosts, and that info is part of the available properties:

/api/v2/entities?entitySelector=type("host")&fields=properties.hostgroupname
