Hi there,

I'm wondering if someone could help me analyse this hot thread output. We have a number of data nodes. All of these data nodes also ingest and index too. We're using ES 5.6

Thank you,  
Ally

Welcome to our community! 😃

Can you upgrade your cluster? 5.X is [EOL](https://www.elastic.co/support/eol).

Thank you! We will be upgrading in the next 6 months but it's a lot easier to get It roadmapped sooner if it'll definitely improve things. Do you reckon that'll help?

It's not really clear what problem you have here?  
If Elasticsearch is only using 30% heap, that seems pretty good to me, even with CPU a little higher.
