io.micrometer @Timed not emitting metrics for @Override method in Java and Springboot App. Tried registering TimedAspect manually

Question

I am trying to capture the metrics for an override method in Java / Springboot. Below is the snippet

@Override
@Timed(value = "processor_timer", histogram = true)
public void preProcess(byte[] key, byte[] event, Headers headers) {
      super.preProcess(key, event, headers);
}

I have added this configuration as well still timer not working for the override method

import io.micrometer.core.aop.TimedAspect;
import io.micrometer.core.instrument.MeterRegistry;
import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;


@Configuration
@EnableAspectJAutoProxy
public class MetricsConfig {

    @Bean
    TimedAspect timedAspect(MeterRegistry registry) {
        return new TimedAspect(registry);

    }

}

Springboot Version

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.4.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
  </parent>

I am calling the preProcess like this

@Slf4j
public abstract class Processor<T> {

    private static final String TIME_HEADER_KEY = "time";
    private static final String ERRORS_HEADER_KEY = "errors";
    String topic;

    public EventProcessor(String topic,) {
        this.topic = topic;
    }

    @Timed(value = "parent_preprocess_event", histogram = true)
    public void preProcess(byte[] key, byte[] event, Headers headers) {
           log.info("Inside parent preProcess");
           T message = extractMessage(event);
           //some business logic

        }
