How can I stop these messages from appearing in the log?

Answer 1

As an alternative to change the logger config, the current Camel sFTP documentation mentions few options you can set on the endpoint:

• jschLoggingLevel
• readLockLoggingLevel
• runLoggingLevel

For example you can set:

sftp://user@myserver.mydomain.net:9921/path/to/folder?binary=true&jschLoggingLevel=WARN&readLockLoggingLevel=INFO&runLoggingLevel=WARN

You can tweak each category to fit your needs directly in the endpoint without changing the configuration of your logger.

Answer 2

If you are using a logger like log4j, you can simply turn off the JSCH logging with the following line in your logger config:

log4j.logger.org.apache.camel.component.file.remote.SftpOperations = OFF
