Returns the full host pool record: identity and resource metadata, AVD configuration (load balancing, max sessions per host,
drain mode, OS, VNet), 7-day session rollups, session capacity percentage, latest CPU and memory, and month-to-date cost.
Cost is one total with no breakdown or date range, and metrics are current or rolled-up values, never series.
Aggregates several sources, so use it per pool rather than iterating a list.
