- return text describing a performance metrics
instance domain
Синопсис C (C Synopsis)
#include <pcp/pmapi.h>
int pmLookupInDomText(pmInDom
indom, int
level, char **
buffer);
cc ... -lpcp
Описание (Description)
Retrieve descriptive text about the performance metrics instance
domain identified by indom.
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 argument level should be PM_TEXT_ONELINE
for a one-line
summary, else PM_TEXT_HELP
for a more verbose description, suited
to a help dialog.
The space pointed to by buffer will have been allocated in
pmLookupInDomText
with malloc(3), and it is the responsibility of
the caller to free(3) the space when it is no longer required.
pmLookupInDomText
returns zero on success.
