Описание (Description)
As part of the Performance Co-Pilot Log Import API (see
LOGIMPORT(3)), pmiAddInstance adds a new element to the instance
domain identified by indom.
indom would normally be constructed using the pmInDom_build
macro, e.g. pmInDom_build(PMI_DOMAIN,0) for the first instance
domain in the Performance Metrics Domain PMI_DOMAIN (which is the
default for all meta data created by the LOGIMPORT library).
The new instance must have both an external name (instance) and
an internal instance identifier (inst) that is unique across all
instances in the indom instance domain. There is a special
``uniqueness rule'' for instance that is imposed by
pmLookupInDom(3), namely that the external instance name must be
unique in the leading non-space characters, e.g. the instance
names ``foo'' and ``foo bar'' are considered the same by this
rule and not allowed in the same instance domain, but ``foo'' and
``foobar'' would be allowed.
Once defined, the external instance name can be used in calls to
pmiGetHandle(3) and/or pmiPutValue(3) with the name of a metric
defined over the same instance domain.
Диагностика (Diagnostic)
pmiAddInstance returns zero on success else a negative value that
can be turned into an error message by calling pmiErrStr(3).
