pmLookupInDomText: return text describing a performance metrics instance domain
NAMEpmLookupInDomText - return text describing a performance metrics instance domain
C SYNOPSIS#include <pcp/pmapi.h>
int pmLookupInDomText(pmInDom indom, int level, char **buffer);
DESCRIPTIONProvided the source of metrics from the current Performance Metrics Application Programming Interface (PMAPI) context is a host, 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.
if the current PMAPI context is an archive log
