The Uhana by VMware dashboard displays a map and related KPI charts. The Uhana by VMware platform contains a framework for dynamically defining and computing KPIs in a real-time system.
The Uhana by VMware dashboard figure represents a dashboard and its parts. See the Dashboard Elements table for callout descriptions.

The following tables provides the data charts available for common data consumption. To get to root causes and remediations, use the Focus menu.
|Average User Throughput||Average DL PDCP user throughput measured as Acknowledged Throughput Volume/Throughput Time where Throughput Volume and Throughput Time exclude the volume and time slot where the DL buffer was emptied|
|Active UE||Downlink Active UEs - Average number of active users in the downlink per active TTI where a user is considered active if it has data pending in the DL buffer|
|Uplink Active UEs||Average number of active users in the uplink per active TTI where a user is considered active if it has data pending in the UL buffer|
|Cell Utilization||DL PRB Cell Utilization - Average DL PRB used computed as the sum of DL PRBs used for initial transmissions and retransmissions and normalized by the total number of PRBs available for the selected ROP (%)|
|UL PRB Cell utilization||Average UL PRB use computed as the sum of UL PRBs used for DTCH and DCCH_CCCH and normalized by the total number of PRBs available for the selected ROP (%)|
|CCE Cell Utilization||Average PDCCH CCE use computed as the weighted sum of CCEs used per aggregation level and normalized by the total number of CCEs available for the selected ROP (%)|
|ERAB Drop Rate||Percentage of UE context and ERAB releases with an abnormal cause code|
|ERAB Setup Failure Rate||Percentage of Initial context and ERAB setups with an abnormal cause code|
|Agg Spectral Efficiency||Average number of DL MAC acknowledged bits carried per resource element (bits/symbol)|
|Avg Cell Throughput||Avg DL PDCP cell throughput measured as total DL PDCP acknowledged volume carried in the selected ROP / Number of seconds in the selected ROP (Mbps)|
|Average Interference||Average uplink interference averaged over all PRBs per antenna branch measured in dBm|
|Bad VoLTE Speech Quality Rate||Percentage of VoLTE sessions considered to have bad uplink VoLTE quality indicated when more than 1% of PDCP packets do not arrive within the packet delay budget (%)|
|UE DL Throughput||Average DL PDCP user throughput for each cell in the selected sector (Mbps)|
|Uplink Interference Spectrogram||Average uplink interference per PRB averaged over selected time range per antenna branch measured in dBm|
|UE DL Throughput||Average DL PDCP user throughput for each cell in the selected sector|
|Active UEs (Uplink)||Average number of active users per active TTI on the uplink|
|Active UEs (Downlink)||Average number of active users per active TTI on the downlink|
|Cell Utilization||Average PDCCH CCE use for each cell in the selected sector|
|DL PRB Cell Utilization||Average DL PRB use for each cell in the selected sector|
