    assertThat(logs).contains("FINER: " + logPrefix + "Info message");
    clock.forwardNanos(100);
    logger.log(ChannelLogLevel.DEBUG, "Debug message");
    tracer.updateBuilder(builder);
    stats = builder.build();
    // DEBUG level messages are not logged to channelz, thus channelz still has the
    // last event.
    assertThat(stats.channelTrace.events).containsExactly(event);
    assertThat(logs).contains("FINEST: " + logPrefix + "Debug message");
}

Example 3 with ChannelStats

use of io.grpc.InternalChannelz.ChannelStats in project grpc-java by grpc.
