Hi,  I would suggest to utilize the forum search.  MIB file is available from support.emc.com  Howver data like LUN, disk status isnt available via SNMP  you could write your own code that use CLI to input to PRTG  or use the existing free monitoring software from EMC
Hi guys, We got an EMC VNX 5200 that should be monitored by PRTG, we need to MIB files that import it to PRTG, if you have better solution, please give me. Do you have any experience? we want to monitro LUN, disk status etc.  Thank you, MSH
