Monitor Service - Command Notification should specify the working directory for command execution

Current Situation

• The CommandFragment element is used to execute operating system commands.
• The system commands are executed using the Java Process API.
• The CommandFragment Notification interface does not explicitly set the working directory of the execution content.
  • This means that the Process API uses the value of the system property user.dir.
  • This property is set to the same value as  jetty.base during the default JOC installation.

Desired Behaviour

• To ensure that commands run in an environment appropriate for the JOC Cockpit service user, the CommandFragment Notification Interface (underlying Process API)  should use the java.io.tmpdir system property.
  • This corresponds to the JETTY_BASE/temp directory.
