Struct UsageMetricsAgentMetric 

pub struct UsageMetricsAgentMetric {
    pub agent_display_name: Option<String>,
    pub agent_name: Option<String>,
    pub model_metrics: HashMap<String, UsageMetricsModelMetric>,
    pub total_api_duration_ms: i64,
    pub total_nano_aiu: f64,
}

Usage attributed to one agent instance, including its identity, API duration, AI units, and per-model breakdown.

Experimental. This type is part of an experimental wire-protocol surface and may change or be removed in future SDK or CLI releases.

Fields

agent_display_name: Option<String>

Human-readable label for this subagent invocation, copied from the originating subagent.started event. For task-tool subagents this is the invocation’s task description rather than the agent’s configured display name, so group by agentName for stable per-agent labels.

agent_name: Option<String>

Configured agent name, when this is a subagent

model_metrics: HashMap<String, UsageMetricsModelMetric>

Per-model usage for this agent, keyed by model identifier

total_api_duration_ms: i64

Time spent in model API calls by this agent, in milliseconds

total_nano_aiu: f64

Accumulated nano-AI units cost for this agent
