Monitored entities API - GET entities list

Lists entities observed within the specified timeframe along with their properties.

You can limit the output by using the pagination:

Specify the number of results per page in the pageSize query parameter.
Then use the cursor from the nextPageKey field of the previous response in the nextPageKey query parameter to obtain subsequent pages.

The request produces an application/json payload.

Parameters

Parameter	Type	Description	In	Required
nextPageKey	string	The cursor for the next page of results. You can find it in the nextPageKey field of the previous response. The first page is always returned if you don't specify the nextPageKey query parameter. When the nextPageKey is set to obtain subsequent pages, you must omit all other query parameters.	query	optional
pageSize	integer	The amount of entities. If not set, 50 is used.	query	optional
entitySelector	string	Defines the scope of the query. Only entities matching the specified criteria are included into response. You need to set one of these criteria: Entity type: `type("TYPE")` Dynatrace entity ID: `entityId("id")`. You can specify several IDs, separated by a comma (`entityId("id-1","id-2")`). And you can add one or several of the following criteria. Values are case-sensitive and the `EQUALS` operator is used unless otherwise specified. Tag: `tag("value")`. Tags in `[context]key:value`, `key:value`, and `value` formats are detected and parsed automatically. If a value-only tag has a colon (`:`) in it, you must escape the colon with a backslash(`\`). Otherwise, the tag will be parsed as a `key:value` tag. All tag values are case-sensitive. Management zone ID: `mzId(123)` Management zone name: `mzName("value")` Entity name: `entityName("value")`. The `CONTAINS` operator is used and the value is not case-sensitive. Health state (HEALTHY,UNHEALTHY): `healthState("HEALTHY")` Entity attribute: `<attribute>("value1","value2")`. For the list of available attributes, see the Entity selector help page. To set several criteria, separate them with a comma (`,`). For example, `type("HOST"),healthState("HEALTHY")`. Only results matching all criteria are included in response. The length of the string is limited to 10,000 characters. The field is required when you're querying the first page of results.	query	optional
from	string	The start of the requested timeframe. You can use one of the following formats: Timestamp in UTC milliseconds. Human-readable format of `2021-01-25T05:57:01.123+01:00`. If no time zone is specified, UTC is used. You can use a space character instead of the `T`. Seconds and fractions of a second are optional. Relative timeframe, back from now. The format is `now-NU/A`, where `N` is the amount of time, `U` is the unit of time, and `A` is an alignment. The alignment rounds all the smaller values to the nearest zero in the past. For example, `now-1y/w` is one year back, aligned by a week. You can also specify relative timeframe without an alignment: `now-NU`. Supported time units for the relative timeframe are: `m`: minutes `h`: hours `d`: days `w`: weeks `M`: months `y`: years If not set, the relative timeframe of three days is used (`now-3d`).	query	optional
to	string	The end of the requested timeframe. You can use one of the following formats: Timestamp in UTC milliseconds. Human-readable format of `2021-01-25T05:57:01.123+01:00`. If no time zone is specified, UTC is used. You can use a space character instead of the `T`. Seconds and fractions of a second are optional. Relative timeframe, back from now. The format is `now-NU/A`, where `N` is the amount of time, `U` is the unit of time, and `A` is an alignment. The alignment rounds all the smaller values to the nearest zero in the past. For example, `now-1y/w` is one year back, aligned by a week. You can also specify relative timeframe without an alignment: `now-NU`. Supported time units for the relative timeframe are: `m`: minutes `h`: hours `d`: days `w`: weeks `M`: months `y`: years If not set, the current timestamp is used.	query	optional
fields	string	Defines the list of entity properties included in the response. The ID and the name of an entity are always included to the response. To add properties, list them with leading plus `+`. You can specify several properties, separated by a comma (for example `fields=+lastSeenTms,+properties.BITNESS`). Use the GET /entityTypes/{type} request to fetch the list of properties available for your entity type. Fields from the properties object must be specified in the `properties.FIELD` format (for example, `properties.BITNESS`).	query	optional

Example

In this example, the request list services that belong to the management zones with the ID of 229130632296508575249. To achieve that, the entitySelector query parameter is set to type("SERVICE"),mzId("9130632296508575249").

Apart from default Dynatrace entity IDs and names of the entities, the request also returns the timestamp of when the service was last seen and the list of technology types that run in the service. To achieve that, the fields query parameter is set to lastSeenTms,properties.serviceTechnologyTypes.

The API token is passed in the Authorization header.

The result is truncated to three entries.
