Hi,
I'm using Metricbeat to collect fields with elasticsearch module. I'm using v.6.8
Currently I cannot find any field related the used heap memory value.
is it correct?

Yeah I think we only have `heap_init_in_bytes` and `heap_max_in_bytes`. Please feel free to open enhancement requests [https://github.com/elastic/beats/issues/new?template=feature-request.md](https://github.com/elastic/beats/issues/new?template=feature-request.md) for metricbeat to add the data you want with more details and/or use cases.

I know that technically I can use X-Pack monitoring feature, but Metricbeat is so lightweight that I can decide to stop/start it whenever I want/need. furthermore, using X-Pack monitoring feature I cannot discriminate destination indices and I need more disk spaces.
For the moment, I will try to ask for an enhancement 🙂
thanks
