Troubleshoot Start the Troubleshooting Workbench with the current object in context.
Object Summary

This widget displays the details of the selected object. The widget also displays the number of resources associated with the selected object and whether the Workload Management is enabled or disabled.

Active Alerts
This widget provides a visual indicator of the alert status for the following alert types.
  • Health alerts that usually require immediate attention.
  • Risk alerts indicating that you must look into any problems shortly.
  • Efficiency alerts indicating that you can reclaim resources.

To see the alerts for the object, click the badge .

Time Remaining

This widget displays the number of days remaining till the projected resource utilization crosses the threshold for the usable capacity.
Capacity Remaining This widget displays the unused capacity of your virtual environment to accommodate new virtual machines.
Virtual Machine Remaining The virtual machine remaining number is based on the average profile. The virtual machine remaining numbers are calculated when you enable one or more custom profiles from the policy. The overall virtual machine remaining is based on the most constrained profile.
Utilization This widget is used to find out the trends in capacity used by a selected cluster as against the total capacity available.
The key utilization indicators are:
  • CPU Capacity Usage
  • Memory Usage
  • Memory Balloon
  • Disk Total IOPS
  • Disk Total Throughput
  • Network Usage Rate
Performance

This widget displays the summary metrics about the overall performance of the object. It displays the latest value and a trend line of the various key performance indicators in a color that indicates its health based on the symptom associated with the metrics. Click each metric to see the expanded chart.

The key performance indicators are:
  • Max VM Memory Contention
  • Worst Consumer Disk Latency
  • Consumers with Memory Contention
  • Consumers with CPU Ready
  • Physical Network Packets Dropped
  • Virtual Network Packets Dropped
Configuration

This widget displays the hardware, CPU, and Network configuration details of the host.
Namespaces Lists the configuration status, current version and Kubernetes status of the namespaces in the cluster.
