pmiputvalue(3)

NAME

   pmiPutValue - add a value for a metric-instance pair

C SYNOPSIS

   #include <pcp/pmapi.h>
   #include <pcp/impl.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).
