Hello,

I have a question about how ES detect the available processors. Here is what I got:  
"os" : {  
"refresh\_interval\_in\_millis" : 1000,  
"name" : "Linux",  
"arch" : "amd64",  
"version" : "4.4.0-87-generic",  
"available\_processors" : 1,  
"allocated\_processors" : 4  
}

The availabe\_processors shows as 1. But in elasticsearch.yml, I use env $NUM\_PROCESSORS (which is 4) to override this value

processors: $ {NUM\_PROCESSORS: 1}

But looks like this doesn't works. I have versions, 6.5.4 has the issue but 6.2.4 doesn't. I searched around but couldn't find anything helpful here.  
Could anyone share some ideas?

Thanks!

`available_processors` is a reflection of how many processors the Operating System reports to the JVM.  
You can configure `processors` all you like, but if the host environment only has 1 processor, then we can't magically make 3 more appear.

In this case:

```auto
  "available_processors" : 1,
  "allocated_processors" : 4

```

your host reports 1 available processor, and you've allocated 4 to Elasticsearch. It looks like everything is working as configured (even though allocating more processors than are evailable doesn't actually make a lot of sense).
