Azure Key Vault

Azure Key Vault is a managed service hosted in the cloud that acts as a central message hub for communication between an IoT application and its attached devices. This integration helps in comprehensive monitoring of your key vaults requests, performance, failures, and latency.

Log and metric types

For Azure Key Vault, you can collect the following logs and metrics:

• Resource logs. To learn more about the different resource log category types and schemas collected for Azure Key Vault, refer to Azure documentation.
• Key Vault Metrics. These metrics are available in Microsoft.KeyVault/vaults namespace.
• Managed HSM Metrics. These metrics are available in Microsoft.KeyVault/managedhsms namespace.

For more information on supported metrics and their units, refer to the Azure documentation.

Setup

Azure service sends monitoring data to Azure Monitor, which can then stream data to Eventhub. Sumo Logic supports:

• Logs collection from Azure Monitor using our Azure Event Hubs source.
• Metrics collection using our HTTP Logs and Metrics source via Azure Functions deployed using the ARM template.

You must explicitly enable diagnostic settings for each Key Vault you want to monitor. You can forward logs to the same event hub provided they satisfy the limitations and permissions as described here.

When you configure the event hubs source or HTTP source, plan your source category to ease the querying process. A hierarchical approach allows you to make use of wildcards. For example: Azure/KeyVault/Logs, Azure/KeyVault/Metrics.

Configure metrics collection

note

Sumo Logic Metrics source is currently in Beta, to participate, contact your Sumo Logic account executive.

1. To set up the Azure Metrics source in Sumo Logic, refer to the shared beta documentation.
2. In the Sumo Logic Azure Metrics source configuration, configure namespaces as Microsoft.KeyVault/vaults and Microsoft.KeyVault/managedhsms.

Configure logs collection

In this section, you will configure a pipeline for shipping diagnostic logs from Azure Monitor to an Event Hub.

Diagnostic logs

1. To set up the Azure Event Hubs source in Sumo Logic, refer to Azure Event Hubs Source for Logs.
2. To create the Diagnostic settings in Azure portal, refer to the Azure documentation. Perform the steps below for each Azure Key Vault namespace that you want to monitor.
   1. Choose Stream to an event hub as the destination.
   2. Select allLogs.
   3. Use the Event Hub namespace and Event Hub name configured in the previous step in the destination details section. You can use the default policy RootManageSharedAccessKey as the policy name.
      
3. Tag the location field in the source with the right location value.
   

Activity Logs

To collect activity logs, refer to the Collecting Logs for the Azure Audit App from Event Hub section in the Azure Audit documentation. Do not perform this step in case you are already collecting activity logs for a subscription.

note

Since this source contains logs from multiple regions, make sure that you do not tag this source with the location tag.

Installing the Azure Key Vault app

Now that you have set up data collection, install the Azure Key Vault Sumo Logic app to use the pre-configured dashboards that provide visibility into your environment for real-time analysis of overall usage.

To install the app:

1. Select App Catalog.
2. In the Search Apps field, search for and then select your app.
3. Optionally, you can scroll down to preview the dashboards included with the app. Then, click Install App (sometimes this button says Add Integration).
4. Click Next.
5. Look for the dialog confirming that your app was installed successfully.
   

Once an app is installed, it will appear in your Personal folder or the folder that you specified. From here, you can share it with other users in your organization. Dashboard panels will automatically start to fill with data matching the time range query received since you created the panel. Results won't be available immediately, but within about 20 minutes, you'll see completed graphs and maps.

Viewing the Azure Key Vault dashboards

All dashboards have a set of filters that you can apply to the entire dashboard. Use these filters to drill down and examine the data to a granular level.

• You can change the time range for a dashboard or panel by selecting a predefined interval from a drop-down list, choosing a recently used time range, or specifying custom dates and times. Learn more.
• You can use template variables to drill down and examine the data on a granular level. For more information, see Filtering Dashboards with Template Variables.
• Most Next-Gen apps allow you to provide the scope at the installation time and are comprised of a key (_sourceCategory by default) and a default value for this key. Based on your input, the app dashboards will be parameterized with a dashboard variable, allowing you to change the dataset queried by all panels. This eliminates the need to create multiple copies of the same dashboard with different queries.
