pmLookupText man page

pmLookupText ā€” return text describing a performance metric

C Synopsis

#include <pcp/pmapi.h>

int pmLookupText(pmID pmid, int level, char **buffer);

cc ... -lpcp


Provided the source of metrics from the current Performance Metrics Application Programming Interface (PMAPI) context is a host, retrieve descriptive text about the performance metric identified by pmid.

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 pmLookupText with malloc(3), and it is the responsibility of the caller to free(3) the space when it is no longer required.

pmLookupText returns zero on success.
