Fetch system parameter from metricbeat index with NEST

Hi Guys,

I am newbie with ElasticStack and want to get the value of system parameters from Metricbeat in my .NET core project but not found any Article to get understand it. Kindly share any sample code or guide for that.

I tried to run below query in KIBANA interface, which gives me plenty of documents.

GET /metricbeat-7.4.2-2019.11.28/_search?pretty

Do I need to mention the parameters (metricset) like CPUUsage, DiskIO etc in the above query ?

Hi, are you looking for how to query system metrics that are collected from Metricbeat in Elasticsearch?

Yes, I want to get values of all system parameters from metricset.name.
