=== Stats, info, and `cat` changes
|
|
|
|
==== Sigar removed
|
|
|
|
We no longer ship the Sigar library for operating system dependent statistics,
|
|
as it no longer seems to be maintained. Instead, we rely on the statistics
|
|
provided by the JVM. This has resulted in a number of changes to the node
|
|
info, and node stats responses:
|
|
|
|
* `network.*` has been removed from nodes info and nodes stats.
|
|
* `fs.*.dev` and `fs.*.disk*` have been removed from nodes stats.
|
|
* `os.*` has been removed from nodes stats, except for `os.timestamp`,
|
|
`os.load_average`, `os.mem.*`, and `os.swap.*`.
|
|
* `os.mem.total` and `os.swap.total` have been removed from nodes info.
|
|
* `process.mem.resident` and `process.mem.share` have been removed from node stats.
|
|
|
|
==== Removed `id_cache` from stats apis
|
|
|
|
Removed `id_cache` metric from nodes stats, indices stats and cluster stats
|
|
apis. This metric has also been removed from the shards cat, indices cat and
|
|
nodes cat apis. Parent/child memory is now reported under fielddata, because
|
|
it has internally be using fielddata for a while now.
|
|
|
|
To just see how much parent/child related field data is taking, the
|
|
`fielddata_fields` option can be used on the stats apis. Indices stats
|
|
example:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
GET /_stats/fielddata?fielddata_fields=_parent
|
|
--------------------------------------------------
|
|
|
|
==== Percolator stats
|
|
|
|
The total time spent running percolator queries is now called `percolate.time`
|
|
instead of `percolate.get_time`.
|
|
|
|
==== Cluster state REST API
|
|
|
|
The cluster state API doesn't return the `routing_nodes` section anymore when
|
|
`routing_table` is requested. The newly introduced `routing_nodes` flag can be
|
|
used separately to control whether `routing_nodes` should be returned.
|
|
|
|
==== Index status API
|
|
|
|
The deprecated index status API has been removed.
|
|
|
|
==== `cat` APIs verbose by default
|
|
|
|
The `cat` APIs now default to being verbose, which means they output column
|
|
headers by default. Verbosity can be turned off with the `v` parameter:
|
|
|
|
[source,sh]
|
|
-----------------
|
|
GET _cat/shards?v=0
|
|
-----------------
