About

MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. 

The following details are configurable per Jenkins job:

• Broker hostname/port
• Topic
• Message

Both the topic and the message may also include certain dynamic variables. These include:

• PROJECT_URL - The relative URL to the Jenkins project to which this job belongs (e.g. "job/my-build").
• BUILD_RESULT - The result of the Job (e.g. SUCCESS, FAILURE, ABORTED, etc.)
• BUILD_NUMBER - The build number
• CULPRITS - Comma-separated list of build culprits

All other build variables and environment variables can also be used (JENKINS-41839).

The default topic when no value is specified is "jenkins/PROJECT_URL".

The default message when no value is specified is "BULD_RESULT".
