NAME
Search::Elasticsearch::Client::1_0::Direct::Cat - A client for running cat debugging
requests
VERSION
version 6.81
DESCRIPTION
The "cat" API in Elasticsearch provides information about your cluster and indices in a
simple, easy to read text format, intended for human consumption.
These APIs have a number of parameters in common:
• "help"
Returns help about the API, eg:
say $e->cat->allocation(help => 1);
• "v"
Includes the column headers in the output:
say $e->cat->allocation(v => 1);
• "h"
Accepts a list of column names to be output, eg:
say $e->cat->indices(h => ['health','index']);
• "bytes"
Formats byte-based values as bytes ("b"), kilobytes ("k"), megabytes ("m") or
gigabytes ("g")
It does Search::Elasticsearch::Role::Client::Direct.
