Parameters

Parameter Type Description In Required

entitySelector

string

Parameter	Type	Description	In	Required
entitySelector	string	Specifies the entities where you want to update tags. You can set one or several of the following criteria: Entity type (required): `type("value")`. 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("ID")` Management zone name: `mzName("value")`. Management zone names are case-sensitive. Health state (HEALTHY,UNHEALTHY): `healthState("HEALTHY")` Dynatrace entity ID: `entityId("id")`. You can specify several IDs, separated by a comma (`entityId("id-1","id-2")`). Dynatrace entity name: `entityName("value")`. You can specify several entity names, separated by a comma (`entityName("name-1","name-2")`). Entity names are case-sensitive. 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.	query	optional
body	AddEntityTags	The JSON body of the request. Contains tags to be added to the matching entities.	body	optional

Specifies the entities where you want to update tags.

You can set one or several of the following criteria:

Entity type (required): type("value").
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("ID")
Management zone name: mzName("value"). Management zone names are case-sensitive.
Health state (HEALTHY,UNHEALTHY): healthState("HEALTHY")
Dynatrace entity ID: entityId("id"). You can specify several IDs, separated by a comma (entityId("id-1","id-2")).
Dynatrace entity name: entityName("value"). You can specify several entity names, separated by a comma (entityName("name-1","name-2")). Entity names are case-sensitive.

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.
