pmID_build, pmID_domain, pmID_cluster, pmID_item - helper methods for manipulating PMIDs
#include <pcp/pmapi.h> pmID pmID_build(unsigned int domain, unsigned int cluster, unsigned int item); unsigned int pmID_domain(pmID pmid); unsigned int pmID_cluster(pmID pmid); unsigned int pmID_item(pmID pmid); cc ... -lpcp
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.
PMAPI(3) and pmIDStr(3).
