The Cluster Stats API allows to retrieve statistics from a cluster wide
|
|
perspective. The API returns basic index metrics (shard numbers, store size,
|
|
memory usage) and information about the current nodes that form the cluster
|
|
(number, roles, os, jvm versions, memory usage, cpu and installed plugins).

// These replacements do a few things:

// 1. Ignore the contents of the `plugins` object because we don't know all of
|
|
// the plugins that will be in it. And because we figure folks don't need to
|
|
// see an exhaustive list anyway.
|
|
// 2. Similarly, ignore the contents of `network_types`, `discovery_types`, and
|
|
// `packaging_types`.
|
|
// 3. Ignore the contents of the (nodes) count object, as what's shown here
|
|
// depends on the license. Voting-only nodes are e.g. only shown when this
|
|
// test runs with a basic license.
|
|
// 4. All of the numbers and strings on the right hand side of *every* field in
|

// the response are ignored. So we're really only asserting things about the

|
// the shape of this response, not the values in it.
