NAME

       pmID_build, pmID_domain, pmID_cluster, pmID_item - helper methods for manipulating PMIDs

C SYNOPSIS

       #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);

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.
