NAME         top

       pmiAddInstance - add an element to an instance domain in a
       LOGIMPORT context

C SYNOPSIS         top

       #include <pcp/pmapi.h>
       #include <pcp/import.h>

Perl SYNOPSIS         top

       use PCP::LogImport;

       pmiAddInstance($indom, $instance, $inst);

DESCRIPTION         top

       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.

DIAGNOSTICS         top

       pmiAddInstance returns zero on success else a negative value that
       can be turned into an error message by calling pmiErrStr(3).
