Struct AgentMetrics 

pub struct AgentMetrics {
    pub trace_id: Option<String>,
    pub llm_calls: usize,
    pub cache_hits: usize,
    pub tool_calls: usize,
    pub compactions: usize,
    pub total_tokens: Option<usize>,
    pub duration: Duration,
}

Aggregated metrics for a single agent execution.

Fields

trace_id: Option<String>

trace_id of this execution (None if absent).

llm_calls: usize

Number of LLM planning calls (plan iterations).

cache_hits: usize

Number of LLM result cache hits that skipped an LLM call.

tool_calls: usize

Number of tool executions (including parallel).

compactions: usize

Number of context compactions performed during the run (0.21.0 S6.1). #[serde(default)] keeps pre-0.21.0 payloads deserializable.

total_tokens: Option<usize>

Cumulative token usage (None if the agent does not report tokens).

duration: Duration

Total duration of a single invoke.

Implementations

impl AgentMetrics

pub fn add_token_usage(&mut self, usage: &TokenUsage)

Accumulates token usage from one LLM call.

pub fn tokens_per_call(&self) -> Option<f64>

Average tokens per LLM call.

pub fn log_summary(&self)

Emits the metrics audit-log line (target: lc_agents::metrics).

Trait Implementations

impl Clone for AgentMetrics

fn clone(&self) -> AgentMetrics

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AgentMetrics

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for AgentMetrics

fn default() -> AgentMetrics

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AgentMetrics

fn deserialize<__D>( __deserializer: __D, ) -> Result<AgentMetrics, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for AgentMetrics

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
