Hi Jianping.Wang,  You should check the collector-manager logs for the snmp-collector that you are using; by default it is Generic-SNMP. You can also increase the logging level by editing the .level value in the logging.properties file, you can increase it to FINE, FINER or FINEST, please note that FINER and FINEST are very verbose and most snmp polling issues should identifiable with the default INFO level.  Unfortunately i cannot provide a definite solution on how to poll the IOPS and LUN data trough snmp as this depends on the SNMP agent and the mib that it is being used.  You can open a service request for assistance with basic functionality however support is limited on custom mask creation. Another option would be to contact professional services to have them assist or create the mask for you.  hth  Regards, Isaka
Hi,      I reconfigured some MIB OID from SRM "MIB Browser" and "SNMP Collector" for no SolutionPackage storage device, like CPU Memory Disk IOPS.       Almost all the configurations used default ones generated by "MIB Browser", now we can see the metrics data for controller's CPU Memory, but no data for LUNs and nodes' IOPS.       There are 2 controllers there, we can see 2 lines in report. These are 2 Nodes there, totally no data. There are many LUNs that may change by time, also no data.      May I know how to configure collection for IOPS and LUNs?
