pmSemStr, pmSemStr_r - convert a performance metric semantic into a string
Contents
C Synopsis
#include<pcp/pmapi.h>constchar*pmSemStr(intsem);char*pmSemStr_r(intsem,char*buf,intbuflen);cc...-lpcp
Description
Given a performance metric semantic, pmSemStr produces a terse ASCII equivalent, appropriate for use in
error and diagnostic messages. The pmSemStr_r function does the same, but stores the result in a user-
supplied buffer buf of length buflen, which should have room for at least 20 bytes.
The value for sem is typically extracted from a pmDesc structure, following a call to pmLookupDesc(3) for
a particular performance metric.
Examples are counter (for sem equals PM_SEM_COUNTER), discrete (for sem equals PM_SEM_DISCRETE), instant
(for sem equals PM_SEM_INSTANT), etc.
