Introduction
A few days ago I worked on a few (s)FTP components. I noticed the amount of logging done by JSCH was quite a lot and polluting our environment. With three SFTP components polling at 15-30 seconds the logging screen in Hawtio felt like it turned into a continuesly scrolling monster that ate my screen estate.
I decided to disable logging of this component and I found something funny, which should be solved by now.
The fix
Normally I use the pax 4j logging config file to specify logging of a deployed bundle. But in this case I tried the log:set command to change the log level of a certain component since the bundle logging setting in the pax 4j file did not change the logging for org.apache.camel.component.file.remote.SftpOperations.
I did some research into it and it turned out there is more than one way to disable the flooding of messages by JSCH.
I did what I would normally do when pax 4j doesnt work, use the log:set but I performed the action on the full bundle name with the command: log:set ERROR org.apache.camel.component.file.remote.SftpOperations
Solved in the new version
This seemed to fix it, but there is still one logger there.
We can see the JSCH is no longer logging, but we still get some flooding caused by a connection.
It’s still too much logging (at least in Hawtio) for my taste but I like this one a lot better.
I did some more research and I found a ticket in JIRA on the Camel site and discovered that they have fixed the logging level of this one last line to DEBUG instead of INFO.
Looking at JIRA, I understand that it has been implemented in the newer versions of Camel FTP.
At the time when I had this behaviour I was still running on Fuse 6.1 with Camel 2.12. Fuse 6.2 has some new and nice features, I guess this is another reason why you should start upgrading soon. I just upgraded to 6.2 and Java 8 and so far it seems all okay to me.
This was my first blog about JBoss Fuse, I hope you enjoyed it and have a very pleasent day.
