Note
|
That while dataflow sends the management.metrics.tags.application as a property it gets converted to a command line arg that is not accepted by the application being run. This is because data flow by default uses the entrypoint exec which moves all properties to commandline args. Meaning the CLI argument for management.metrics.tags.application is empty.
