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