@lalit-satapathy , are you good to approve the PR from your end?

@harnish-elastic , i examined the information available here to determine if the fields are of type gauge or counter. But, i couldnt find any relevant information.

Do you have any source that is used to annotate the various metric_type added as part of this PR?

I have also tried to find documents useful for adding metric_type as part of this PR, however, I couldn't find any docs. I have also referred to the doc that you have provided and based on the description and data collection, I have added metric_type fields.
