Cluster Statsedit
The cluster-stats
API provides similar output to the node-stats
. There is
one crucial difference: Node Stats shows you statistics per node, while
cluster-stats
shows you the sum total of all nodes in a single metric.
This provides some useful stats to glance at. You can see for example, that your
entire cluster is using 50% of the available heap or that filter cache is not
evicting heavily. Its main use is to provide a quick summary that is more
extensive than the cluster-health
, but less detailed than node-stats
. It is
also useful for clusters that are very large, which makes node-stats
output
difficult to read.
The API may be invoked as follows:
GET _cluster/stats
