Problem
Morpheus shows health problems with the instances, as if they were down, but they are actually up and you are able to connect to them with no issues.
Solution
There are two possible solutions to the problem:
Restarting the agent
Connect to the instance and restart the agent as a super user
sudo morpheus-node-ctl restart morphd
Upgrade the morpheus agent
Alternatively, you may take this opportunity to update the morpheus agent to its latest version, which will force a clean restart as well.
You can do so by connecting to the instance and using the package manager of the system to update it. For example:
CentOS 7:
sudo yum -y upgrade morpheus-vm-node sudo morpheus-node-ctl reconfigure
Ubuntu:
sudo apt-get update morpheus-vm-node sudo apt-get install -y morpheus-vm-node sudo morpheus-node-ctl reconfigure
Alternatively, you can use the morpheus command line interface if you have it set up to trigger an update with:
morpheus hosts upgrade-agent <instance_name>
