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 an archive log,
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 an archive log
- PM_ERR_INDOM_LOG
- indom is not a defined instance domain identifier for the archive
log
- PM_ERR_INST_LOG
- the external instance name is not known for the instance domain
indom in the archive log
