Alert rules that are defined for each health criterion aren't displayed in the Azure portal. You can enable or disable a health alert rule only in the [Workload Monitor API](https://docs.microsoft.com/rest/api/monitor/microsoft.workloadmonitor/components). Also, you can't assign an [Azure Monitor action group](platform/action-groups.md) for health alerts in the Azure portal. You can only use the notification setting API to configure an action group to be triggered whenever a health alert is fired. Currently, you can assign action groups against a VM so that all *health alerts* fired against the VM trigger the same action groups. Unlike traditional Azure alerts, there's no concept of a separate action group for each health alert rule. Additionally, only action groups that are configured to provide email or SMS notifications are supported when health alerts are triggered.

Our performance charts have been updated to use data stored in the *InsightsMetrics* table. To see data in these charts you will need to upgrade to use the new VM Insights solution. Please refer to our [GA FAQ](insights/vminsights-ga-release-faq.md) for additional information.

With this upgrade, Azure Monitor for VMs performance data are stored in the same *InsightsMetrics* table as [Azure Monitor for containers](container-insights-overview.md), which makes it easier for you to query the two data sets. Also, you are able to store more diverse data sets that we could not store in the table previously used.

In the past, we enabled the ServiceMap solution on your workspace and setup performance counters in your Log Analytics workspace to send the data to the *Perf* table. This new solution sends the data to a table named *InsightsMetrics* that is also used by Azure Monitor for containers. This table schema allows us to store additional metrics and service data sets that are not compatible with the *Perf* table format.

## How do I upgrade?
3640
When a Log Analytics workspace is upgraded to the latest version of Azure Monitor to VMs, it will upgrade the dependency agent on each of the VMs attached to that workspace. Each VM requiring upgrade will be identified in the **Get Started** tab in Azure Monitor for VMs in the Azure portal. When you choose to upgrade a VM, it will upgrade the workspace for that VM along with any other VMs attached to that workspace. You can select a single VM or multiple VMs, resource groups, or subscriptions.
