Class AsyncTimerExec

java.lang.Object

org.apache.hc.client5.http.observation.interceptors.AsyncTimerExec

All Implemented Interfaces:

AsyncExecChainHandler

public final class AsyncTimerExec
extends Object
implements AsyncExecChainHandler

Records request latency and response counters for asynchronous clients.

Meters:

• <prefix>.request (timer) — latency, uses MetricConfig.slo and MetricConfig.percentiles
• <prefix>.response (counter) — result count
• <prefix>.inflight (gauge, kind=async) — in-flight request count

Tags: method, status, and when ObservingOptions.TagLevel#EXTENDED also protocol, target. Any MetricConfig.commonTags are appended.
