Overview
pmdaDesc uses the standard PMDA(3) data structures to return the pmDesc description in desc for the metric identified by pmid.
Diagnostics
If the pmid does not correspond to any metric supported by this PMDA, pmdaDesc returns PM_ERR_PMID.
Caveat
The PMDA must be using PMDA_INTERFACE_2 or later, as specified in the call to pmdaDSO(3) or pmdaDaemon(3).
