…Replace pmval with pmrep for live metrics retrieval

  • Replace pmval --archive with pmrep -a for archived metrics
  • Replace pmstat with pmrep using SAR metric sets (:sar-u, :sar-r, :sar-d)
  • Remove deprecated flags (-f, -d) that are not needed with pmrep

Benefits:

  • pmrep can monitor multiple metrics in a single command
  • Consolidates multiple tools (pmval, pmstat) into one consistent interface
  • Provides better output formatting options (CSV, JSON, table)
  • Reduces cognitive load for readers learning PCP monitoring
