Hello
I would like to propose very simple change in documentation. I am missing a documentation of all metrics in this exporter.
Long story short
There are two teams in our company, monitoring and elastic team. Monitoring team asked me to provide all useful metrics I need to work with before they configure federation from elastic's team prometheus. The reason was that they do not want to federate all metrics, just a subset of useful ones. It was difficult for me to get all metrics because I had no access to the API of ElasticSearch. So I had to communicate with another team and ask them to provide me requested information.
TL;DR
I found it useful to have all metrics documented.
What do you think?
Best regards
Jozef
