Title: Weird ruby process in App Engine Flexible instance
Tags: google-app-engine;app-engine-flexible
Question: I am connecting via ssh to one of an App Engine Flex instances with .Net Core application running on it and get this:
Where does that ruby process(with 24% cpu usage) come from? Is it some internal google service?

Here is the accepted answer: The running Ruby process is /usr/sbin/google-fluentd. This package contains the logger agent which is the basis of Stackdriver Logging and it is written in Ruby gem as explained in this document. All in all, the Ruby process is using the CPU because the application’s logging.
As an aside, I noticed that the screenshot you uploaded contains your account-id and project-id. I strongly suggest you to re-upload the picture without this information for security and privacy reasons.
