NAME

       pmiPutValue - add a value for a metric-instance pair

C SYNOPSIS

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

       int pmiPutValue(const char *name, const char *instance, const char *value);

       cc ... -lpcp_import -lpcp

Perl SYNOPSIS

       use PCP::LogImport;

       pmiPutValue($name, $instance, $value);

DESCRIPTION

       As  part of the Performance Co-Pilot Log Import API (see LOGIMPORT(3)), pmiPutValue adds a
       single value to the current output record for a given metric and instance.

       The metric's name should match one defined earlier in a call to pmiAddMetric(3).

       For singular metrics (those  defined  with  an  instance  domain  of  PM_INDOM_NULL),  the
       instance should be NULL or an empty string, otherwise instance should match the name of an
       instance defined earlier in a call to pmiAddInstance(3) for the metric's instance domain.

       The value should be in a format consistent with the metric's type as defined in  the  call
       to pmiAddMetric(3).

       No  data  will be written until pmiWrite(3) is called, so multiple calls to pmiPutValue or
       pmiPutValueHandle(3) are typically used to accumulate  data  values  for  several  metric-
       instance pairs before calling pmiWrite(3).

DIAGNOSTICS

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