DESCRIPTION
List all available services and their statuses
Use this command to list all running services on this machine.
Services fall into main categories (GENERIC, GRPC, REST, API) and are then organized by tags (broker, data, idm, etc.)
EXAMPLE
Use the --tags/-t flag to limit display to one specific tag, use lowercase for tags.
$ ` + os.Args[0] + ` ps -t=broker
Will result:
- pydio.grpc.activity [X]
- pydio.grpc.chat [X]
- pydio.grpc.mailer [X]
- pydio.api.websocket [X]
- pydio.rest.activity [X]
- pydio.rest.frontlogs [X]
- pydio.rest.mailer [X]
