DESCRIPTION

13       The "cat" API in Elasticsearch provides information about your cluster
14       and indices in a simple, easy to read text format, intended for human
15       consumption.
16
17       These APIs have a number of parameters in common:
18
19       •   "help"
20
21           Returns help about the API, eg:
22
23               say $e->cat->allocation(help => 1);
24
25       •   "v"
26
27           Includes the column headers in the output:
28
29               say $e->cat->allocation(v => 1);
30
31       •   "h"
32
33           Accepts a list of column names to be output, eg:
34
35               say $e->cat->indices(h => ['health','index']);
36
37       •   "bytes"
38
39           Formats byte-based values as bytes ("b"), kilobytes ("k"),
40           megabytes ("m") or gigabytes ("g")
41
42       It does Search::Elasticsearch::Role::Client::Direct.
