store in a `long`, so is returned as a string so that the value returned can
exactly match what the underlying operating system interface returns. Any
value that is too large to parse into a `long` almost certainly means no
limit has been set for the cgroup.

`usage_in_bytes` (Linux only)::

The total current memory usage by processes in the cgroup (in bytes) by all

# return just process for node with IP address 10.0.0.1
GET /_nodes/10.0.0.1/stats/process
--------------------------------------------------

All stats can be explicitly requested via `/_nodes/stats/_all` or
`/_nodes/stats?metric=_all`.

You can get information about indices stats on `node`, `indices`, or `shards`
level.

[source,console]
--------------------------------------------------
# Fielddata summarized by node
GET /_nodes/stats/indices/fielddata?fields=field1,field2

# Fielddata summarized by node and index
GET /_nodes/stats/indices/fielddata?level=indices&fields=field1,field2

# Fielddata summarized by node, index, and shard
GET /_nodes/stats/indices/fielddata?level=shards&fields=field1,field2

# You can use wildcards for field names
GET /_nodes/stats/indices/fielddata?fields=field*
--------------------------------------------------

You can get statistics about search groups for searches executed
on this node.

[source,console]
--------------------------------------------------
# All groups with all stats
GET /_nodes/stats?groups=_all

# Some groups from just the indices stats
GET /_nodes/stats/indices?groups=foo,bar

===== Retrieve ingest statistics only

To return only ingest-related node statistics, set the `<metric>` path
parameter to `ingest` and use the
<<common-options-response-filtering,`filter_path`>> query parameter.

[source,console]
--------------------------------------------------
GET /_nodes/stats/ingest?filter_path=nodes.*.ingest
--------------------------------------------------

You can use the `metric` and `filter_path` query parameters to get the same
response.

[source,console]
--------------------------------------------------
GET /_nodes/stats?metric=ingest&filter_path=nodes.*.ingest
--------------------------------------------------

To further refine the response, change the `filter_path` value.
For example, the following request only returns ingest pipeline statistics.

[source,console]
--------------------------------------------------
GET /_nodes/stats?metric=ingest&filter_path=nodes.*.ingest.pipelines
--------------------------------------------------
