24.1.4 Monitor data center temperature

The appliance provides detailed monitoring data that you can use to determine the power and cooling capabilities of the devices in your data center. The overall cooling in your data center might be sufficient; however, there might be areas that are insufficiently cooled due to conditions such as poor airflow, concentration of excessive heat output, or wrap-around airflow at the ends of aisles. To easily identify temperature issues and look for thermal hotspots in all areas in your data center, use the 3D visualization features provided by the Data Centers UI screen.

To learn more about temperature, see “Monitoring power and temperature” (page 179).

24.2.1 Best practices for monitoring health with the appliance UI

HP recommends the following best practices to monitor the health of the managed resources in your environment.

NOTE: The status represented for all HP OneView resources represents the status for that single resource and does not represent the roll-up status of sub-components. For example, the status for an enclosure does not aggregate status for all blades and servers, but rather just the status of the enclosure (Onboard Administrator, fans, and power supplies).
