pmdaProfile — update instance profile for PMDA in preparation for the next fetch from PMCD
C Synopsis
#include <pcp/pmapi.h>
#include <pcp/pmda.h>
int pmdaProfile(pmProfile *prof, pmdaExt *pmda);
cc ... -lpcp_pmda -lpcp
Description
As part of the Performance Metrics Domain Agent (PMDA) API (see PMDA(3)), pmdaProfile is the default callback which handles the receipt of a pmProfile from pmcd(1). A profile describes the instances that pmcd requires in the pmResult structure returned by the next fetch. pmdaProfile simply stores the new profile.
Caveat
The PMDA must be using PMDA_PROTOCOL_2 or later, as specified in the call to pmdaDSO(3) or pmdaDaemon(3).
