[[cat-allocation]]
== cat allocation

`allocation` provides a snapshot of how many shards are allocated to each data node
and how much disk space they are using.

% curl '192.168.56.10:9200/_cat/allocation?v'

Here we can see that each node has been allocated a single shard and
that they're all using about the same amount of space.
