The API returns the following response:

|
|
|
[source,txt]
|
|
--------------------------------------------------
|
|
id host ip node
|
|
YzWoH_2BT-6UjVGDyPdqYg 127.0.0.1 127.0.0.1 YzWoH_2
|
|
--------------------------------------------------
|
|
// TESTRESPONSE[s/YzWoH_2.+/.+/ non_json]
|
|
|
|
This information is also available via the `nodes` command, but this
|
|
is slightly shorter when all you want to do, for example, is verify
|
|
all nodes agree on the master:

|
