Hosts API - GET all hosts

We have a new version of this API—Entity API v2. Check it out!

Gets the list of all hosts in your Dynatrace environment, along with their parameters.

The full list can be lengthy, so you can narrow it down by specifying filter parameters, like tags. See the Parameters section for more details.

You can additionally limit the output by using the pagination:

  1. Specify the number of results per page in the pageSize query parameter.
  2. Then use the cursor from the Next-Page-Key response header in the nextPageKey query parameter to obtain subsequent pages.

The request produces an application/json payload.

GET
  • Managed https://{your-domain}/e/{your-environment-id}/api/v1/entity/infrastructure/hosts
  • SaaS https://{your-environment-id}.live.dynatrace.com/api/v1/entity/infrastructure/hosts
  • Environment ActiveGate https://{your-activegate-domain}/e/{your-environment-id}/api/v1/entity/infrastructure/hosts

Authentication

To execute this request, you need the Access problem and event feed, metrics, and topology (DataExport) permission assigned to your API token. To learn how to obtain and use it, see Tokens and authentication.

Parameters

The timeframe is restricted to a maximum period of 3 days.

Parameter Type Description In Required
startTimestamp integer

The start timestamp of the requested timeframe, in milliseconds (UTC).

If not set, then 72 hours behind from now is used.

 query optional
endTimestamp integer

The end timestamp of the requested timeframe, in milliseconds (UTC).

If not set, then the current timestamp is used.

The timeframe must not exceed 3 days.

 query optional
relativeTime string

The relative timeframe, back from now.

 query optional
tag array

Filters the resulting set of hosts by the specified tag. You can specify several tags in the following format: tag=tag1&tag=tag2. The host has to match all the specified tags.

In case of key-value tags, such as imported AWS or CloudFoundry tags, use the following format: tag=[context]key:value. For custom key-value tags, omit the context: tag=key:value.

 query optional
showMonitoringCandidates boolean

Includes (true) or excludes (false) a monitoring candidate in the response.

Monitoring candidates are network entities that are detected but not monitored.

 query optional
entity array

Filters result to the specified hosts only.

To specify several hosts use the following format: entity=ID1&entity=ID2.

 query optional
managementZone integer

Only return hosts that are part of the specified management zone.

 query optional
hostGroupId string

Filters the resulting set of hosts by the specified host group.

Specify the Dynatrace IDs of the host group you're interested in.

 query optional
hostGroupName string

Filters the resulting set of hosts by the specified host group.

Specify the name of the host group you're interested in.

 query optional
includeDetails boolean

Includes (true) or excludes (false) details which are queried from related entities.

Excluding details may make queries faster.

If not set, then true is used.

 query optional
pageSize integer

The number of hosts per result page.

If not set, pagination is not used and the result contains all hosts fitting the specified filtering criteria.

 query optional
nextPageKey string

The cursor for the next page of results. You can find it in the Next-Page-Key header of the previous response.

If you're using pagination, the first page is always returned without this cursor.

You must keep all other query parameters as they were in the first request to obtain subsequent pages.

 query optional
