Struct Exemplar

pub struct Exemplar {
    pub attachments: Option<Vec<HashMap<String, Value>>>,
    pub timestamp: Option<DateTime<Utc>>,
    pub value: Option<f64>,
}

Exemplars are example points that may be used to annotate aggregated distribution values. They are metadata that gives information about a particular value added to a Distribution bucket, such as a trace ID that was active when a value was added. They may contain further information, such as a example values and timestamps, origin, etc.

This type is not used in any activity, and only used as part of another schema.

Fields

attachments: Option<Vec<HashMap<String, Value>>>

Contextual information about the example value. Examples are: Trace: type.googleapis.com/google.monitoring.v3.SpanContext Literal string: type.googleapis.com/google.protobuf.StringValue Labels dropped during aggregation: type.googleapis.com/google.monitoring.v3.DroppedLabels There may be only a single attachment of any given message type in a single exemplar, and this is enforced by the system.

timestamp: Option<DateTime<Utc>>

The observation (sampling) time of the above value.

value: Option<f64>

Value of the exemplar point. This value determines to which bucket the exemplar belongs.
