Allegedly, VMware Cloud Director has MQTT capabilities.
This seems like a bit of an excess to add in a simple little set of tools...
OTOH... Adding MQTT clients to a small management VM & using SSH to run them is an option.
I've created a VM named Skeeter with a user named skeeter.
Skeeter has openssh-server & mosquitto-clients installed.
Skeeter also has mosquitto installed for testing purposes.
So...
Open an SSH session to Skeeter & subscribe to a topic:
mosquitto_sub -h localhost -t "mqtt" -v
Then send a publish to Skeeter using ssh:
ssh skeeter@skeeter "mosquitto_pub -h localhost -t 'mqtt' -m 'Hello MQTT'"
You'll see "mqtt Hello MQTT" appear in the SSH session.
w00t!
Next trick... Set up passwordless SSH from the ESXi server to Skeeter. DONE
Trick(s) after that... Lotsa telemetry & stuff for monitoring the ESXi server in your Automation systems.
