## es\_node\_stats()

## def('key')

## es\_local\_index\_meta(key => 'base' || 'index')

Fetch meta-data from the local config file, i.e. `~/.es-utils.yaml`.

Format is:

    ---
    meta:
      index_name:
        key: value
      index_basename:
        key: value

The most specific version is searched first, followed by the index stripped of
it's date, and then on through all the bases discovered with
`es_index_bases()`.

This is used by the `es-search.pl` utility to do lookups of the **timestamp**
field it needs to sort documents, i.e.:

    ---
    meta:
      logstash:
        timestamp: '@timestamp'
        host: es-cluster-01.int.example.com
      bro:
        timestamp: 'timestamp'
