pmiAddInstance − add an element to an instance domain in a LOGIMPORT context
int pmiAddInstance(pmInDom indom, const char *instance, int inst);
cc ... −lpcp_import −lpcp
pmiAddInstance($indom, $instance, $inst);
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.
pmiAddInstance returns zero on success else a negative value that can be turned into an error message by calling pmiErrStr(3).
