PMNAMEINDOMARCHIVE(3) Library Functions Manual PMNAMEINDOMARCHIVE(3)
pmNameInDomArchive - translate an instance identifier into an
instance name
#include <pcp/pmapi.h>
int pmNameInDomArchive(pmInDom indom, int inst, char **name);
cc ... -lpcp
Provided that the current Performance Metrics Application
Programming Interface (PMAPI) context is associated with a set of
archive logs, pmNameInDomArchive will scan the union of all the
instance domain metadata for the instance domain indom, locate
the first instance with the internal instance identifier given by
inst, and return the full external instance identification via
name.
This routine is a specialized version of the more general PMAPI
routine pmNameInDom.
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.
The space for the value of name will have been allocated in
pmNameInDomArchive with malloc(3), and it is the responsibility
of the caller to free(3) the space when it is no longer required.
pmNameInDomArchive returns zero on success.
PMAPI(3), pmGetConfig(3), pmGetInDomArchive(3),
pmLookupInDomArchive(3), pmNameInDom(3), pcp.conf(5) and
pcp.env(5).
PM_ERR_NOTARCHIVE
the current PMAPI context is not associated with a set of
archive logs
PM_ERR_INDOM_LOG
indom is not a defined instance domain identifier for the
set of archive logs
PM_ERR_INST_LOG
the instance identifier inst is not known for the instance
domain indom in the set of archive logs
