NAME         top

       pmiWrite - flush data to a LOGIMPORT archive

C SYNOPSIS         top

       #include <pcp/pmapi.h>
       #include <pcp/import.h>

       int pmiWrite(int sec, int usec);

Perl SYNOPSIS         top

       use PCP::LogImport;

       pmiWrite($sec, $usec);

DESCRIPTION         top

       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         top

       pmiWrite returns zero on success else a negative value that can
       be turned into an error message by calling pmiErrStr(3).
