The `watch` command provides a mechanism to watch for changes in a particular
|
|
|
|
|
data view (list of nodes, service members, key value, etc) and to invoke a
|
|
|
|
|
process with the latest values of the view. If no process is specified, the
|
|
|
|
|
current values are dumped to stdout which can be a useful way to inspect data
|
|
|
|
|
in Consul.
