Struct GraphNodeHealth 

pub struct GraphNodeHealth {
    pub node: NodeId,
    pub started: u64,
    pub completed: u64,
    pub failed: u64,
}

Health rollup for a single graph node across one run.

A graph node is the graph’s unit of work — frequently a delegated agent or tool call (see crate::graph::SubAgentNode) — so per-node success/failure counts double as tool health telemetry for the graph. Counts are derived from durable GraphObservations by correlating node.started with node.completed / node.failed.

Fields

node: NodeId

The node these counts describe.

started: u64

Number of node.started observations seen.

completed: u64

Number of node.completed observations seen.

failed: u64

Number of node.failed observations seen.

Implementations

impl GraphNodeHealth

pub fn attempts(&self) -> u64

Terminal attempts (completed + failed) — activations with a known outcome. started may exceed this while a node is still running.

pub fn failure_rate(&self) -> f64

Fraction of terminal attempts that failed, in 0.0..=1.0. Returns 0.0 when the node has no terminal attempts yet.

pub fn is_healthy(&self) -> bool

True when the node has never failed.
