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.

PMIWRITE(3) Library Functions Manual PMIWRITE(3)NAME
pmiWrite - flush data to a LOGIMPORT archive
C SYNOPSIS
#include <pcp/pmapi.h>
#include <pcp/impl.h>
#include <pcp/import.h>
int pmiWrite(int sec, int usec);
cc ... -lpcp_import -lpcp
Perl SYNOPSIS
use PCP::LogImport;
pmiWrite($sec, $usec);
DESCRIPTION
As part of the Performance Co-Pilot Log Import API (see LOGIMPORT(3)), pmiWrite forces accumulated data values out to the PCP archive.
The data values and associated metadata have previously been built up using calls to pmiAddMetric(3), pmiAddInstance(3), pmiPutValue(3) and
pmiPutValueHandle(3).
The current set of data values and any new metadata is written to the archive with a timestamp of sec and usec in the source timezone of
the archive, see pmiSetTimezone(3).
DIAGNOSTICS
pmiWrite returns zero on success else a negative value that can be turned into an error message by calling pmiErrStr(3).
SEE ALSO LOGIMPORT(3), pmiAddInstance(3), pmiAddMetric(3), pmiErrStr(3), pmiPutValue(3), pmiPutValueHandle(3) and pmiSetTimezone(3).
