So I want to build a dashboard with _introspection index , some of the metrics I am looking for are THP (enabled/disabled), Ulimits, CPU, Mem, Disk usage, swap usage, clocks sync (realtime & hardware) etc. I couldnt find any solid documentation for _introspection index as to under which source, component these variables will be stored also what all data is available in the index. Can someone please point me to a doumented list of all the data points in the index if any docs exists. Also any specific component/source I can find the KPIs I mentioned above.
