## DESCRIPTION
|
|
|
|
|
|
|
|
|
|
`nodegroupattrip` queries the confluent server to get information about nodes.
|
|
|
|
|
In the simplest form, it simply takes the given group and lists the attributes of that group.
|
|
|
|
|
|
|
|
|
|
Contrasted with nodeattrib(8), settings managed by nodegroupattrib will be added
|
|
|
|
|
and removed from a node as it is added or removed from a group. If an attribute
|
|
|
|
|
is set using nodeattrib(8) against a noderange(5) that happens to be a group name,
|
|
|
|
|
nodeattrib(8) individually sets attributes directly on each individual node that is
|
|
|
|
|
currently a member of that group. Removing group membership or adding a new
|
|
|
|
|
node after using the nodeattrib(8) command will not have attributes change automatically.
|
|
|
|
|
It's easiest to see by using the `nodeattrib <noderange> -b` to understand how
|
|
|
|
|
the attributes are set on the node versus a group to which a node belongs.

## OPTIONS
|
|
|
|
|
|
|
|
|
|
* `-c`, `--clear`:
|
|
|
|
|
Clear specified nodeattributes.
|
|
|
|
|
|
|
|
|
|
## EXAMPLES
|
|
|
|
|
|
|
|
|
|
* Show attributes of a group called `demogrp`:
|
|
|
|
|
`# nodegroupattrib demogrp`
|
|
|
|
|
`demogrp: hardwaremanagement.manager: (will derive from expression 10.30.{n0/255}.{n0%255})`
|
|
|
|
|
`demogrp: nodes: n12,n13,n10,n11,n9,n1,n2,n3,n4`
|
|
|
|
|
|
|
|
|
|
* Set location.u to be the remainder of first number in node name when divided by 42:
|
|
|
|
|
`# nodegroupattrib demogrp location.u={n1%42}`
|
|
|
