NAME
pmiGetHandle - define a handle for a metric-instance pair C SYNOPSIS
#include <pcp/pmapi.h> #include <pcp/impl.h> #include <pcp/import.h> int pmiGetHandle(const char *name, const char *instance); cc ... -lpcp_import -lpcp Perl SYNOPSIS use PCP::LogImport; $handle = pmiGetHandle($name, $instance); DESCRIPTION
As part of the Performance Co-Pilot Log Import API (see LOGIMPORT(3)), pmiGetHandle creates a handle for a given metric and instance. The handle is returned as the value from the pmiGetHandle call and can be used in subsequent calls to pmiPutValueHandle(3). 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. When combined with pmiPutValueHandle(3), the use of handles provide a performance improvement over the alternative lookup for a metric name and an instance name for each data value that is required for pmiPutValue(3). DIAGNOSTICS
On failure pmiGetHandle returns a negative value that can be turned into an error message by calling pmiErrStr(3). SEE ALSO

NAME
pmiPutValueHandle - add a value for a metric-instance pair via a handle C SYNOPSIS
#include <pcp/pmapi.h> #include <pcp/impl.h> #include <pcp/import.h> int pmiPutValueHandle(int handle, const char *value); cc ... -lpcp_import -lpcp Perl SYNOPSIS use PCP::LogImport; pmiPutValueHandle($handle, $value); DESCRIPTION
As part of the Performance Co-Pilot Log Import API (see LOGIMPORT(3)), pmiPutValueHandle adds a single value to the current output record for a given metric and instance, using the handle defined by an earlier call to pmiGetHandle(3). 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 pmiPutValueHandle or pmiPutValue(3) are typically used to accumu- late data values for several metric-instance pairs before calling pmiWrite(3). DIAGNOSTICS
pmiPutValueHandle returns zero on success else a negative value that can be turned into an error message by calling pmiErrStr(3). SEE ALSO
