On every VerneMQ node you'll find the
vmq-admincommand line tool in the release's bin directory (in case you use the binary VerneMQ packages,
vmq-adminshould already be callable in your path, without changing directories). It has different sub-commands that let you check for status, start and stop listeners, re-configure values and a couple of other administrative tasks.
vmq-adminhas different sub-commands with a lot of respective options. You can familiarize yourself by using the
--helpoption on the different levels of
vmq-admin. You might see additional sub-commands in case integrated plugins are running (
vmq-admin bridgeis an example).
