Parameters

Parameter	Type	Description	In	Required
entitySelector	string	Specifies the entities where you want to update tags. 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.	query	required
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 24 hours is used (`now-24h`).	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
