[jchmielewska]

Objective:

• NebulOuS agent tries to recover from failure in communications with NebulOuS core and provides sufficient logs to identify the root of the problem.

Preconditions:

• NebulOuS agent is installed on a manually-managed node and running correctly.
• User is logged in the machine and has appropriate rights for accessing NebulOuS agent logs.
• “Dummy APP” is registered in NebulOuS and an instance is running on the node.

Steps:

1. Action:
   • NebulOuS agent can no longer contact NebulOuS core due some network issues (e.g: LAN cable disconnected, NebulOuS core goes down, etc…).

Expected results:

• User can see relevant logs.
• NebulOuS agent actively tries to resume normal operation.
• Application running on the node is terminated.

2. Action:
   • Link with NebulOuS core is recovered.

Expected results:

• NebulOuS agent resumes normal operation briefly. User can see relevant logs.
