PMIUNITS(3)						     Library Functions Manual						       PMIUNITS(3)

NAME
pmiUnits, pmiID, pmiInDom - construct core metric data structures C SYNOPSIS
#include <pcp/pmapi.h> #include <pcp/import.h> pmID pmiID(int domain, int cluster, int item); pmInDom pmiInDom(int domain, int serial); pmUnits pmiUnits(int dimSpace, int dimTime, int dimCount, int scaleSpace, int scaleTime, int scaleCount); cc ... -lpcp_import -lpcp Perl SYNOPSIS use PCP::LogImport; $pmid = pmiID($domain, $cluster, $item); $indom = pmiInDom($domain, $serial); $units = pmiUnits($dimSpace, $dimTime, $dimCount, $scaleSpace, $scaleTime, $scaleCount); DESCRIPTION
As part of the Performance Co-Pilot Log Import API (see LOGIMPORT(3)), these routines provide convenience methods (especially for script use) for constructing pmID, pmInDom and pmUnits structures respectively, to be used in subsequent calls to pmiAddMetric(3) and pmiAddIn- stance(3). Refer to pmLookupDesc(3) for a complete description of the values and semantics of the components of a pmUnits structure, and hence the valid argument values for pmiUnits. DIAGNOSTICS
None. SEE ALSO
LOGIMPORT(3), pmiAddMetric(3), pmiAddInstance(3) and pmLookupDesc(3). Performance Co-Pilot PCP PMIUNITS(3)

PMIADDINSTANCE(3)					     Library Functions Manual						 PMIADDINSTANCE(3)

NAME
pmiAddInstance - add an element to an instance domain in a LOGIMPORT context C SYNOPSIS
#include <pcp/pmapi.h> #include <pcp/impl.h> #include <pcp/import.h> int pmiAddInstance(pmInDom indom, const char *instance, int inst); cc ... -lpcp_import -lpcp Perl SYNOPSIS use PCP::LogImport; pmiAddInstance($indom, $instance, $inst); DESCRIPTION
As part of the Performance Co-Pilot Log Import API (see LOGIMPORT(3)), pmiAddInstance adds a new element to the instance domain identified by indom. indom would normally be constructed using the pmInDom_build macro, e.g. pmInDom_build(PMI_DOMAIN,0) for the first instance domain in the Performance Metrics Domain PMI_DOMAIN (which is the default for all meta data created by the LOGIMPORT library). The new instance must have both an external name (instance) and an internal instance identifier (inst) that is unique across all instances in the indom instance domain. There is a special ``uniqueness rule'' for instance that is imposed by pmLookupInDom(3), namely that the external instance name must be unique in the leading non-space characters, e.g. the instance names ``foo'' and ``foo bar'' are considered the same by this rule and not allowed in the same instance domain, but ``foo'' and ``foobar'' would be allowed. Once defined, the external instance name can be used in calls to pmiGetHandle(3) and/or pmiPutValue(3) with the name of a metric defined over the same instance domain. DIAGNOSTICS
pmiAddInstance returns zero on success else a negative value that can be turned into an error message by calling pmiErrStr(3). SEE ALSO
LOGIMPORT(3), pmiAddMetric(3), pmiErrStr(3), pmiGetHandle(3), pmiPutValue(3) and pmLookupInDom(3). Performance Co-Pilot PMIADDINSTANCE(3)
