Enum MetadataAction 

pub enum MetadataAction {
    Delete,
    AddAlias {
        target_entity_id: EntityId,
    },
    RemoveAlias {
        target_entity_id: EntityId,
    },
    SetTags {
        cardinality: OriginTagCardinality,
        tags: TagSet,
    },
    AttachExternalData {
        external_data: ExternalData,
    },
}

A metadata action.

Variants

Delete

Delete all metadata for the entity.

AddAlias

Adds an alias to the entity.

This can be used to allow for querying for information about an entity, where the information isn’t directly associated with the entity itself. For example, process ID entities usually are aliased to an underlying container ID entity, where the container ID entity itself is the one with associated tags and so on. When querying for the tags of the process ID entity, an alias to the container ID entity can be established to instead allow for getting the container ID entity’s tags.

Fields

target_entity_id: EntityId

Entity ID of the target to alias to.

RemoveAlias

Removes an alias to the entity.

Fields

target_entity_id: EntityId

Entity ID of the target to remove the alias to.

SetTags

Sets the tags for the entity.

This overwrites any existing tags for the entity.

Fields

cardinality: OriginTagCardinality

Cardinality to set the tags at.

tags: TagSet

Tags to set.

AttachExternalData

Attaches External Data to the entity.

External Data is free-form string data that’s attached to entities from external systems to allow resolving the entity’s ID when it can’t be passed directly to the entity such that the entity can provide it in telemetry payloads itself.

Fields

external_data: ExternalData

External Data to attach.
