Описание (Description)

Within the Performance Co-Pilot (PCP) each metric is assigned a unique Performance Metric Identifier (pmID). Internally a pmID is constructed from 3 fields: the domain number (of the associated Performance Metrics Domain Agent, or PMDA), the cluster number and the item number (the last two are assigned by the PMDA).

pmID_build constructs a pmID from domain, cluster and item.

pmID_domain, pmID_cluster and pmID_item return the respective fields from pmid.
