The first few columns tell you where your nodes live. For sanity it
also tells you what version of ES and the JVM each one runs.

The last columns provide ancillary information that can often be
useful when looking at the cluster as a whole, particularly large
ones. How many master-eligible nodes do I have? How many client
nodes? It looks like someone restarted a node recently; which one was
it?

=== Columns
Below is an exhaustive list of the existing headers that can be
passed to `nodes?h=` to retrieve the relevant details in ordered
columns. If no headers are specified, then those marked to Appear
by Default will appear. If any header is specified, then the defaults
are not used.
Aliases can be used in place of the full header name for brevity.
Columns appear in the order that they are listed below unless a
different order is specified (e.g., `h=pid,id` versus `h=id,pid`).
When specifying headers, the headers are not placed in the output
by default. To have the headers appear in the output, use verbose
mode (`v`). The header name will match the supplied value (e.g.,
`pid` versus `p`). For example:

Add file descriptor details to cat/nodes cat/nodes currently does not report any details related to file descriptors. This adds the current number in use, the maximum number available as well as their ratio (percentage) to cat/nodes as hidden-by-default metrics. In addition, this also adds current heap usage (as a non-percentage of ts max) and ram usage (as a non-percerntage of its max) to allow tools to provide more granularity. Closes #7652
