1 Title: New checks for EMC VPLEX: emc_vplex_cpu, emc_vplex_director_stats, emc_vplex_if, emc_vplex_volumes
9 These new checks provide information for
12 <li>Director disks IO throughput and latency</li>
13 <li>Directors frontend and backend interface statistics</li>
14 <li>Directors CPU utilization</li>
15 <li>Volume IO throughput and latency</li>
18 Note: The EMC VPLEX devices currently do not provide a SysDescr OID, which is
19 considered as a bug. If you want to discover these checks you need to configure
20 these hosts with the rule <i>"Hosts without system description OID"</i> (snmp_without_sys_descr).
21 Otherwise these devices will fail at the start of the service discovery.
23 Additional note: It seems that the snmp information is only updated every 90 seconds.
24 We highly recommend to set the check interval for these checks (actually the Check_MK check)
25 to 120 seconds. If you query the system every minute there will be errors in the rate computation
26 of the interfaces and other side effects.
