Stats, info, and cat changes
editStats, info, and cat
changes
editSigar removed
editWe 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
andfs.*.disk*
have been removed from nodes stats. -
os.*
has been removed from nodes stats, except foros.timestamp
,os.load_average
,os.mem.*
, andos.swap.*
. -
os.mem.total
andos.swap.total
have been removed from nodes info. -
process.mem.resident
andprocess.mem.share
have been removed from node stats.
Removed id_cache
from stats apis
editRemoved 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 been 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:
GET /_stats/fielddata?fielddata_fields=_parent
Percolator stats
editThe total time spent running percolator queries is now called percolate.time
instead of percolate.get_time
.
Cluster state REST API
editThe 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
editThe deprecated index status API has been removed.
Nodes Stats API
editQueue lengths are now reported as basic numeric so they can easily processed by code. Before we used a human
readable format. For example, a queue with 1,000 items is now reported as 1000
instead of 1k
.
