NAME         top

       pmiPutValue - add a value for a metric-instance pair

C SYNOPSIS         top

       #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         top

       use PCP::LogImport;

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

DESCRIPTION         top

       As   part   of  the  Performance  Co-Pilot  Log  Import  API  (see
       LOGIMPORT(3)), pmiPutValue adds a single value to the current out‐
       put 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         top

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