PMPRINTVALUE(3) Library Functions Manual PMPRINTVALUE(3)NAME
pmPrintValue - print a performance metric value
C SYNOPSIS
#include <stdio.h>
#include <pcp/pmapi.h>
void pmPrintValue(FILE *f, int valfmt, int type, const pmValue *val, int minwidth);
cc ... -lpcp
DESCRIPTION
The value of a single performance metric (as identified by val) is printed on the standard I/O stream identified by f.
The value of the performance metric is interpreted according to the format of val as defined by valfmt (from a pmValueSet within a pmResult
structure; see pmFetch(3)) and the generic description of the metrics type passed in via type.
The value for type is typically extracted from a pmDesc structure, following a call to pmLookupDesc(3) for a particular performance metric.
The output will be optionally padded to be at least minwidth characters wide.
pmPrintValue is most useful for displaying values of performance metrics from pmFetch(3) (which returns a set of valfmt and val pairs for
each requested metric), based upon the metrics type as returned from pmLookupDesc(3).
