EMC PowerMAX, VMAX and TDEV monitoring
XorMon NG does not monitor TDEVs. Storage Groups are monitored instead, let us explain why:
There could be easilly tenth of thousands TDEVs on each monitored storage.
It would require to issue tenth of thousands REST API queries to get all data we need regularly (every 5 minutes).
EMC Unisphere is not able to cope with it within reasonable time.
