Hi, if you are using the default Linux process monitoring template, you can replace it with the following one to solve the problem of no alarm when the process exits abnormally ```yml # Licensed to the Apache Software Foundation (ASF) under one or more # contributor license agreements.

It supports SSH account password or key authentication.
