I have setup a cluster of 3 ES nodes (5.1.1), all three nodes are listed in the elasticsearch output plugin in logstash and the cluster is healthy.

Looking at the thread\_pool, one of my nodes does not seem to be doing as much as the others and it is not a master.

Every now and again it processes one bulk request but most of the time its only one management thread active.

ES master/data  
ES1 data  
ES2 data

```
node_name name active queue rejected

It also seems most under utilised

```

Is it causing issues?

Are shards being indexed into distributed evenly across the nodes?

@warkolm it is not causing issues but I was investigating a bottleneck and this looked very strange

@Christian_Dahlqvist The shards are distributed pretty evenly across the nodes

```
shards disk.indices disk.used disk.avail disk.total disk.percent host ip node
    51 7.2gb 12.1gb 27gb 39.2gb 30 10.195.3.69 10.195.3.69 elk-poc-es2
    50 6.8gb 11.2gb 28gb 39.2gb 28 10.195.134.187 10.195.134.187 elk-poc-es
    51 8.8gb 13.4gb 25.7gb 39.2gb 34 10.83.31.213 10.83.31.213 elk-poc-es1
```
