Please format your code using </> icon as explained in this guide. It will make your post more readable.
Or use markdown style like:
```

```
Is that right?
Yes.
With several indices, how do I select default index in Kibana?
There is a little 
icon close to the index name to make it the default one.
If having multiple indices is an issue, you can reproduce the way it was somewhat done internally in elasticsearch with multiple types (not really like this but you'll get the idea) and index your documents like:
{
"log": {
// Your log content here
},
"state": {
// Your state content here
},
"counter": {
// Your counter content here
}
}
But it's less efficient IMO.
