cat nodeattrsedit

The nodeattrs command shows custom node attributes. For example:

GET /_cat/nodeattrs?v

Could look like:

node    host      ip        attr     value
EK_AsJb 127.0.0.1 127.0.0.1 testattr test

The first few columns (node, host, ip) give you basic info per node and the attr and value columns give you the custom node attributes, one per line.

Columnsedit

Below is an exhaustive list of the existing headers that can be passed to nodeattrs?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=attr,value versus h=value,attr).

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:

GET /_cat/nodeattrs?v&h=name,pid,attr,value

Might look like:

name    pid   attr     value
EK_AsJb 19566 testattr test
