Azure App Service Plan

Azure App Service Plan defines a set of compute resources for a app service to run. This integration helps in monitoring memory, CPU, incoming and outgoing bandwidth, number of sockets and their states across all the instances of the plan.

Log and metric types

For Azure App Service Plan, you can collect the following metrics:

• Activity logs, provides insight into any subscription-level or management group level events that have occurred in the Azure. To learn more, refer to Azure documentation.

• Platform Metrics for Azure App Service Plan. These metrics are available in the Microsoft.Web/serverfarms namespace. For more information on supported metrics, refer to the Azure documentation. App Service Plan metrics are available only for plans in Basic, Standard, Premium and Isolated tiers.

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 Azure App Service plan 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/AppServicePlan/Logs, Azure/AppServicePlan/Metrics.

Configure metric rules

Azure Observability Metadata Extraction Service Level

If this rule already exists, there's no need to create it again.

Rule Name: AzureObservabilityMetadataExtractionWebAppServerFarmLevel

Metric match expression

resourceId=/SUBSCRIPTIONS/*/RESOURCEGROUPS/*/PROVIDERS/*/SERVERFARMS/* tenant_name=*

Fields extracted	Metric rule
subscription_id	$resourceId._1
resource_group	$resourceId._2
provider_name	$resourceId._3
resource_type	SERVERFARMS
resource_name	$resourceId._4

Configure metrics collection

In this section, you will configure a pipeline for shipping metrics from Azure Monitor to an Event Hub, on to an Azure Function, and finally to an HTTP Source on a hosted collector in Sumo Logic.

1. Configure an HTTP Source.
2. Configure and deploy the ARM Template.
3. Export metrics to Event Hub. Perform below steps for each Azure App Service plan that you want to monitor.
   1. Choose Stream to an event hub as destination.
   2. Select AllMetrics.
   3. Use the Event hub namespace created by the ARM template in Step 2 above. You can create a new Event hub or use the one created by ARM template. You can use the default policy RootManageSharedAccessKey as the policy name.
4. Tag the location field in the source with right location value.
   

Configure logs collection

Diagnostic logs

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

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 setting in the Azure portal, refer to the Azure documentation. Perform the below steps for each Azure Functions that you want to monitor.
   1. Choose Stream to an event hub as the destination.
   2. Select AllMetrics.
   3. Use the Event Hub namespace and Event Hub name configured in previous step in destination details section. You can use the default policy RootManageSharedAccessKey as the policy name.
      
3. Tag the location field in the source with right location value.
   

Activity logs (optional)

To collect activity logs, follow the instructions here. If you are already collecting activity logs for a subscription, do not perform this step.

Installing the Azure App Service Plan app

This section provides instructions on how to install the Azure App Service Plan app, and shows examples of each of the preconfigured dashboards you can use to analyze your data.

To install the app, do the following:

1. Select App Catalog.
2. In the 🔎 Search Apps field, run a search for your desired app, then select it.
3. Click Install App.
   note

   Sometimes this button says Add Integration.

4. Click Next in the Setup Data section.
5. In the Configure section of your respective app, complete the following fields.
   1. Key. Select either of these options for the data source.
      • Choose Source Category and select a source category from the list for Default Value.
      • Choose Custom, and enter a custom metadata field. Insert its value in Default Value.
6. Click Next. You will be redirected to the Preview & Done section.

Post-installation

Once your app is installed, it will appear in your Installed Apps folder, and dashboard panels will start to fill automatically.

Each panel slowly fills with data matching the time range query and received since the panel was created. Results will not immediately be available, but will update with full graphs and charts over time.

Viewing Azure App Service Plan 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.
