All Implemented Interfaces:

MeterBinder

public class PoolingHttpClientConnectionManagerMetricsBinder
extends Object
implements MeterBinder

Collects metrics from a ConnPoolControl, for example PoolingHttpClientConnectionManager for synchronous HTTP clients or PoolingNHttpClientConnectionManager for asynchronous HTTP clients.

It monitors the overall connection pool state. Usage example:

      PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager();
      HttpClient httpClient = HttpClientBuilder.create().setConnectionManager(connectionManager).build();
      new PoolingHttpClientConnectionManagerMetricsBinder(connectionManager, "my-pool").bindTo(registry);
 

See PoolingHttpClientConnectionManagerMetricsBinder for Apache HTTP client 5 support.

Since:

1.3.0
