Meaning of processors in elasticsearch

I am viewing my cluster stats in an Elasticsearch deployment by executing the

GET _cluster/stats

command on kibana's web console.

Regarding os.processors info, I see this

    "os" : {
      "available_processors" : 6,
      "allocated_processors" : 6,

Given that I have a 3-node cluster, does the above imply that I have 6/3=2 processors on each node?

CodePudding user response：

From the _cluster/stats documentation (emphasis added):

available_processors (integer) Number of processors available to JVM across all selected nodes.

allocated_processors (integer) Number of processors used to calculate thread pool size across all selected nodes. This number can be set with the processors setting of a node and defaults to the number of processors reported by the OS. In both cases, this number will never be larger than 32.

So, to answer your question, it means you have 6 processors in total, but it could be that one node has 4 and two other nodes have only 1.

In order to know how many processor each node has, you need to hit the _nodes/stats endpoint instead, which will contain the same fields, but relative to each node.
