Parameters

Parameter Type Description In Required
entitySelector string

Specifies the entities where you want to update tags.

You must 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")).

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. Any colons (:) that are part of the key or value must be escaped with a backslash(\), otherwise, it will be interpreted as the separator between the key and the value. All tag values are case-sensitive.
  • Management zone ID: mzId(123)
  • Management zone name: mzName("value")
  • Entity name: entityName("value"). By default this filters for entities, whose name contains the given value and is not case sensitive. The following modifications are available:
    • entityName.equals: changes the operator to EQUALS.
    • entityName.startsWith: changes the operator to BEGINS WITH.
    • entityName.in: enables you to provide multiple values. The EQUALS operator applies.
    • caseSensitive(entityName("value")): takes any entity name criterion as an arguments and makes the value case-sensitive.
  • Health state (HEALTHY,UNHEALTHY): healthState("HEALTHY")
  • First seen timestamp: firstSeenTms.<operator>(now-3h). Use any timestamp format from the from/to parameters. The following operators are available:
    • lte: earlier than or at the specified time
    • lt: earlier than the specified time
    • gte: later than or at the specified time
    • gt: later than the specified time
  • Entity attribute: <attribute>("value1","value2") and <attribute>.exists(). To fetch the list of available attributes, execute the GET all entity types and check the properties field.
  • Relationships: fromRelationships.<relationshipName>() and toRelationships.<relationshipName>(). The criterion takes an entity selector as an attribute. To fetch the list of available relationships, execute the GET all entity types and check the fromRelationships and toRelationships fields.
  • Negation: not(<criterion>). Inverts any criterion except for type.

For more information, see Entity selector in Dynatrace Documentation.

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.
