== cat nodeattrs
|
|
|
|
The `nodeattrs` command shows custom node attributes.
|
|
For example:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
GET /_cat/nodeattrs?v
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
|
|
Could look like:
|
|
|
|
[source,txt]
|
|
--------------------------------------------------
|
|
node host ip attr value
|
|
EK_AsJb 127.0.0.1 127.0.0.1 testattr test
|
|
--------------------------------------------------
|
|
// TESTRESPONSE[s/EK_AsJb/.+/ _cat]
|
|
|
|
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.
|
|
|
|

|
|
=== Columns
|
|
|
|
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:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
GET /_cat/nodeattrs?v&h=name,pid,attr,value
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
|
|
Might look like:
|
|
|
|
[source,txt]
|
|
--------------------------------------------------
|
|
name pid attr value
|
|
EK_AsJb 19566 testattr test
|
|
--------------------------------------------------
|
|
// TESTRESPONSE[s/EK_AsJb/.+/ s/19566/\\d*/ _cat]
