To help you investigate and troubleshoot problems with your cluster and host systems that might occur in the future, you can create dashboards and views that apply the troubleshooting tools and solutions that you used to research and solve the problems with your host system, to make those troubleshooting tools and solutions available for future use.
To readily view the status of your cluster and host systems when your CIO asks you about their health, you can use the decision support dashboards on the vRealize Operations Manager Home page. For example, you can:
Use the vSphere Clusters dashboard to view the utilization index, CPU demand, and memory use for your clusters. This dashboard also tracks the net use and disk I/O operations.
Use vSphere Cluster Configuration Summary dashboard to track the high availability status, and other configuration items.
Use the vSphere Hosts Overview to examine the capacity levels of your cluster, host systems, and virtual machines.
Use the Health of Host Systems dashboard to view the active alert list, capacity metric chart and heatmap for your host system.
Or, you might need to create your own dashboards to track the status of your clusters and host systems.
If you work in a Network Operations Center environment and have multiple monitors, you can run multiple instances of vRealize Operations Manager, and dedicate a monitor to each specific dashboard so that you can visually track the status of your objects.
Create an alert definition to alert you when the capacity of your host system is getting low. See Create a New Alert Definition.
- In the menu, click Dashboards and look through the list of existing dashboards to determine whether you can use the cluster and host system dashboards to track your clusters and host systems.
- Click the Health of Host Systems dashboard, and review the widgets included on it.
The inclusion of the Object List, Alert List, Metric Picker, Metric Chart, Heatmap, and Top-N widgets would allow you to easily peruse the status of the host systems that you select in the Object List widget. This dashboard has the widget interaction configured so that the object you select in the Object List widget is the object for which the other widgets display data.
- Create and configure a new dashboard that has widgets to monitor the health of your host systems and generate alerts.
- Above the dashboard view, click Actions and select Create Dashboard.
- In the New Dashboard workspace, for the Dashboard Name, enter Health of Host Systems, and leave the other default settings.
- In the Widget List workspace, add the Object List widget and configure it to display host system objects.
- Add the Alert List widget to the dashboard, and configure it to display capacity alerts when the capacity of your host systems becomes an immediate risk.
- In the Widget Interactions workspace, for each widget listed, select the Object List widget as the provider to drive the data to the other widgets, and click Apply Interactions.
- In the Dashboard Navigation workspace, select the dashboards that receive data from the selected widgets, and click Apply Navigations.
After vRealize Operations Manager collects data, if a problem occurs with the capacity of your host systems, the Alert List widget on your new dashboard displays the alerts that are configured for your host systems.
What to do next
Prepare to share information with others, plan for growth and new projects, and use policies to continuously monitor all of the objects in your environment. See Reports, Planning the Capacity for Your Managed Environment Using vRealize Operations Manager, and Policies.
