Mule ESB CloudHub No listener found for request and Available listeners are

Question

Multiple applications are deployed to Mule CloudHub and their logs are being cluttered/spammed with someone attempting to send some sort of request:

No listener found for request: (GET)/


No listener found for request: (POST)/azenv.php


No listener found for request: (HEAD)/robots.txt


No listener found for request: (GET)/manager/html

as an example, and:

Available listeners are: [listed available API endpoints, won't expose them here]

Due to application logs being limited to a certain amount of MB and time, these spammy logs are cluttering and pushing back important ones.

The listener is using the HTTP protocol.

Ways of dealing with that, that I know of, are setting up a VPC and/or at least use HTTPS with TSL/SSL. What are other options other than VPC and HTTPS?

Answer 1

The simplest approach is just switching the log level of the class triggering those logs to a "higher" level. That information should be available in the full log entries but I believe the class is org.mule.module.http.internal.listener.HttpListenerRegistry and a WARN level should do.
