Discovery Log

 

When you click on the link "Here", Horizontal Discovery Log shows the pattern failed at step "guard against unrunnable commands"

 

Release


From Jakarta

 

Cause


This is due to missing credential privileges being used by Discovery.  For Docker Virtualization discovery we require the credential to be root or the credential should be a member of the docker

group.  This is detailed in our product documentation here under the section User Privileges. 

Resolution



Either use a root credential or add the user credential to the docker group by logging into the Linux server targeted by Discovery and running the command "sudo usermod -a -G user_name docker".

This will add Linux user with name "user_name" to the group "docker".
