Spring Actuator /Health Logger set to OFF, yet still logging

I want to set the Logger for just the /health actuator endpoint to OFF in the application.properties file. Application is on Spring Boot 1.5. The /health would be our new monitoring url for the F5. I don't want to flood the logs. I have this.

    logging.level.org.springframework.web=DEBUG

    org.springframework.boot.actuate.health.Logger=OFF
    logging.level.org.springframework.boot.actuate.health=OFF

I'm still getting DEBUG logging in the console and the log file. The only thing that works is setting the first one to INFO or higher. But, that is not desirable. So, right now i'm getting this

2020-05-06 17:14:01.545 DEBUG 58588 --- [nio-9095-exec-5] o.s.web.servlet.DispatcherServlet        : DispatcherServlet with name 'dispatcherServlet' processing GET request for [/health]
2020-05-06 17:14:01.552 DEBUG 58588 --- [nio-9095-exec-5] o.s.web.servlet.DispatcherServlet        : Last-Modified value for [/health] is: -1

2020-05-06 17:14:01.849 DEBUG 58588 --- [nio-9095-exec-5] o.s.web.servlet.DispatcherServlet        : Null ModelAndView returned to DispatcherServlet with name 'dispatcherServlet': assuming HandlerAdapter completed request handling

Do i need to set a different logger property? For a different class/package?

I use logback, so I added a logging filter for this. You need to change the regexes to match your own logging format.

package eu.stackoverflow.logging;

import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.filter.Filter;
import ch.qos.logback.core.spi.FilterReply;
import java.util.HashSet;
import java.util.Set;
import java.util.regex.Pattern;

public class IgnoringHealthAndPrometheusLoggingFilter extends Filter<ILoggingEvent> {

    private static final Pattern HEALTH_OR_PROMETHEUS =
        Pattern.compile("GET \"/(health|prometheus)\", parameters=\\{}");
    private static final Pattern COMPLETED =
        Pattern.compile("Completed 200 OK");

    private Set<String> activeThreads = new HashSet<>();

    @Override
    public FilterReply decide(ILoggingEvent loggingEvent) {
        if (isHealthOrPrometheus(loggingEvent.getMessage())) {
            activeThreads.add(loggingEvent.getThreadName());
            return FilterReply.DENY;
        } else if (isCompleted200Ok(loggingEvent.getMessage()) && activeThreads.remove(loggingEvent.getThreadName())) {
            return FilterReply.DENY;
        } else {
            return FilterReply.ACCEPT;
        }
    }

    private boolean isHealthOrPrometheus(String message) {
        return HEALTH_OR_PROMETHEUS.matcher(message).matches();
    }

    private boolean isCompleted200Ok(String message) {
        return COMPLETED.matcher(message).matches();
    }
}

    <appender class="ch.qos.logback.core.ConsoleAppender" name="CONSOLE">
        <filter class="eu.stackoverflow.logging.IgnoringHealthAndPrometheusLoggingFilter" />
    </appender>
