These new checks provide information for

• Director disks IO throughput and latency
• Directors frontend and backend interface statistics
• Directors CPU utilization
• Volume IO throughput and latency

Note: The EMC VPLEX devices currently do not provide a SysDescr OID, which is considered as a bug. If you want to discover these checks you need to configure these hosts with the rule "Hosts without system description OID" (snmp_without_sys_descr). Otherwise these devices will fail at the start of the service discovery.

Additional note: It seems that the snmp information is only updated every 90 seconds. We highly recommend to set the check interval for these checks (actually the Check_MK check) to 120 seconds. If you query the system every minute there will be errors in the rate computation of the interfaces and other side effects.
