Troubleshooting
33 Benchmark the Performance, Reliability and Scalability of Dell EMC OpenManage Enterprise Power Manager
2.0 in Data Center Environment
13 Troubleshooting
13.1 Metric Collection happening at non-regular intervals in a scaled
datacenter environment
Issue
In the Metrics and Monitoring graphs for Individual Devices and Static Groups, the metric collection has
happened at non-regular intervals when compared to the configuration set in Power Manager Setting for
Metric Gathering Interval.
Metric Collection happening at non-regular intervals irrespective of the configuration set in Power
Manager Setting for Metric Gathering Interval.
Resolution
Metric collection can happen at irregular intervals due to the following conditions in a datacenter environment.
• More than 10 percent of the Power Manager monitored devices are not reachable.
• Insufficient VM resources allocated or the resource consumption of guest VM is much higher that
would cause the appliance to slow down.
• Network bandwidth lesser than 10Mbps or latency greater than 500ms.
To rectify the issue, ensure that the following conditions are met:
• All the monitored devices are reachable and responsive to the management protocols. For more
information about the management protocols, see OpenManage Enterprise Power Manager User’s
Guide.
• Allocate sufficient resources to the VM.
• Ensure that there are no network latency issues.
