Hi to all,
I'm interested in finding an introduction about Performance Tuning under Unix (or Linux); can somebody please point me in the right direction?
Best regards (1 Reply)

PMDANAME(3) Library Functions Manual PMDANAME(3)NAME
pmdaName - translate a PMID to a set of dynamic performance metric names
C SYNOPSIS
#include <pcp/pmapi.h>
#include <pcp/impl.h>
#include <pcp/pmda.h>
int pmdaName(pmID pmid, char ***nameset, pmdaExt *pmda);
cc ... -lpcp_pmda -lpcp
DESCRIPTION
As part of the Performance Metrics Domain Agent (PMDA) API (see PMDA(3)), pmdaName is the generic callback for translating a pmid into one
or more dynamic metric names (nameset).
Because implementing dynamic performance metrics requires specific PMDA support, and the facility is an optional component of a PMDA (most
PMDAs do not support dynamic performance metrics), pmdaName is a skeleton implementation that returns PM_ERR_NAME.
A PMDA that supports dynamic performance metrics will provide a private callback that replaces pmdaName (by assignment to version.four.name
of the pmdaInterface structure) and implements the translation from a pmid to a set of dynamic performance metric names returned via name-
set. The behaviour, return values and memory allocation rules for nameset are the same as for pmNameAll(3).
DIAGNOSTICS
pmdaName returns PM_ERR_PMID if the name is not recognized or cannot be translated, otherwise the number of metric names found (most com-
monly 1).
CAVEAT
The PMDA must be using PMDA_PROTOCOL_4 or later, as specified in the call to pmdaDSO(3) or pmdaDaemon(3).
