cat nodeattrs
editcat nodeattrs
editThe nodeattrs
command shows custom node attributes.
% curl 192.168.56.10:9200/_cat/nodeattrs node host ip attr value Black Bolt epsilon 192.168.1.8 rack rack314 Black Bolt epsilon 192.168.1.8 azone us-east-1
The first few columns give you basic info per node.
node host ip Black Bolt epsilon 192.168.1.8 Black Bolt epsilon 192.168.1.8
The attr and value columns can give you a picture of custom node attributes.
attr value rack rack314 azone us-east-1
Columns
editBelow 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=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:
% curl 192.168.56.10:9200/_cat/nodeattrs?v&h=name,pid,attr,value name pid attr value Black Bolt 28000 rack rack314 Black Bolt 28000 azone us-east-1
