Struct NodeObservation 

pub struct NodeObservation {
    pub span_id: String,
    pub run_id: String,
    pub conversation_id: String,
    pub node_type: String,
    pub started_at: DateTime<Utc>,
    pub duration_ms: u64,
    pub data: NodeObservationData,
    pub metadata: HashMap<String, Value>,
}

Observation data captured during node execution

Contains all input/output information needed for tracing. The structure varies based on node type (LLM vs Tool).

Fields

span_id: String

Unique identifier for this observation/span

run_id: String

Run identifier for the overall graph execution

conversation_id: String

Conversation/thread identifier

node_type: String

Node type: “llm” or “tool”

started_at: DateTime<Utc>

Timestamp when node execution started

duration_ms: u64

Duration of node execution in milliseconds

data: NodeObservationData

Input/output data specific to node type

metadata: HashMap<String, Value>

Optional metadata
