Hi there,

I'm using ES 5.0.1 with X-Pack with only Monitoring activated on a basic license. In Kibana, if I go to Monitoring -\> My cluster -\> Elasticsearch -\> Indexes, I get the error in the title. I checked (briefly) with tcpdump, and I appear to be indeed getting a JSON-formatted response from Elasticsearch when I click the page. The response is huge though, so I'm not sure if maybe there is a formatting error in there somewhere.

This used to work properly yesterday, with no changes in the meantime except indexing more data. I have 260 indexes currently. Has anybody else hit this problem? Any help is greatly appreciated.

Best,  
Dan

Hi Dan,

Can you provide the mappings and settings for the latest `.monitoring-es-2-*` index?

```auto
GET /<.monitoring-es-2-{now}>?pretty

```

Thanks

It should be the default, I haven't modified it. You can see it here: [https://gist.github.com/dandrestor/2de1062564063760b83a16317bb64ef4](https://gist.github.com/dandrestor/2de1062564063760b83a16317bb64ef4) (it's too long to post here).
