NAME

Search::Elasticsearch::Client::6_0::Direct::Cat - A client for running cat debugging requests

VERSION

version 6.00

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.

recovery()

    say $e->cat->recovery(
        index => 'index' | \@indices    # optional
    );

Provides a view of shard replication. It will show information anytime data from at least one shard is copying to a different node. It can also show up on cluster restarts. If your recovery process seems stuck, try it to see if there’s any movement using recovery().

Query string parameters: bytes, error_trace, format, h, help, human, master_timeout, s, v

See the cat recovery docs for more information.

repositories()

    say $e->cat->repositories()

Provides a list of registered snapshot repositories.
