pmLookupInDomArchive: translate an instance name into an instance identifier

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 archive logs, 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.

PM_ERR_INDOM_LOG

PM_ERR_INST_LOG

the external instance name is not known for the instance domain indom in the set of archive logs
