PMIPUTVALUE(3) Library Functions Manual PMIPUTVALUE(3)
pmiPutValue - add a value for a metric-instance pair
#include <pcp/pmapi.h>
#include <pcp/import.h>
int pmiPutValue(const char *name, const char *instance,
const char *value);
cc ... -lpcp_import -lpcp
use PCP::LogImport;
pmiPutValue($name, $instance, $value);
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).
pmiPutValue returns zero on success else a negative value that can be
turned into an error message by calling pmiErrStr(3).
