NAME
pmLookupInDomArchive - translate an instance name into an instance identifier
C SYNOPSIS
#include <pcp/pmapi.h>
int pmLookupInDomArchive(pmInDom indom, const char *name);
cc ... -lpcp
DESCRIPTION
Provided the current Performance Metrics Application Programming Interface (PMAPI) context is associated with a set of archives, pmLookupInDomArchive will scan the union of all the instance domain metadata for the instance domain indom, locate the first instance with the external identification given by name, and return the internal instance identifier.
This routine is a specialized version of the more general PMAPI routine pmLookupInDom.
Only the leading non-space characters of name will be used to identify the instance.
The value for the instance domain indom is typically extracted from a pmDesc structure, following a call to pmLookupDesc(3) for a particular performance metric.
pmLookupInDomArchive will return a positive instance identifier on success.
DIAGNOSTICS
PM_ERR_NOTARCHIVE
the current PMAPI context is not associated with a set of archives
PM_ERR_INDOM_LOG
indom is not a defined instance domain identifier for the set of archives
PM_ERR_INST_LOG
the external instance name is not known for the instance domain indom in the set of archives
