Historian Thread Count Increase and Tag Differences

1. What are the common causes for an increase in the Historian Thread Count? Understanding these factors will help us manage system performance effectively.
2. Could you explain the difference between the tags .{Diagnostics}.Health.HISTORIAN.Historian.ThreadCount and .Sys.Historian Thread Count? I’d like to ensure we’re monitoring the correct metrics.

Your insights and any relevant documentation would be greatly appreciated.
