If you are using the CommandBox Bullet Train module, the Service Manager will contribute its own bullet train car that shows you the stats of the default server for a given directory.
You can turn this additional car on or off by setting the following config setting in the bullet train module:
config set modules.commandbox-bullet-train.serverServiceEnable=false
You can customize the background color as well like so:
config set modules.commandbox-bullet-train.serverServiceBG=grey
Remember, the status text in the car can be green, red, yellow, or orange, so choose a color that doesn't render the text unreadable.
You can change the order the car appears in the prompt using the name
serverService like so:
config set modules.commandbox-bullet-train.carOrder=boxVersion,package,serverService,status,execTime
