Azure App Service Environment

An Azure App Service Environment is an Azure App Service feature that provides a fully isolated and dedicated environment for running App Service apps securely at high scale. This integration helps in monitoring your environments operational events such as upgrades, scaling, and suspensions.

The below instructions applies to App Service Environment v3.

Log and metric types

For Azure App Service Environment, you can collect the following logs:

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

• App Service Environment Platform Logs. Logs are only emitted when your App Service Environment has an event (for example, a scale operation with an App Service Environment) that triggers the logs. To learn more about the different situations and messages collected for Azure App Service Environment, 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.

You must explicitly enable diagnostic settings for each Azure App Service Environment 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/AppServiceEnvironment/Logs, Azure/AppServiceEnvironment/Metrics.

Configure field in field schema

1. Classic UI. In the main Sumo Logic menu, select Manage Data > Logs > Fields.
   New UI. In the top menu select Configuration, and then under Logs select Fields. You can also click the Go To... menu at the top of the screen and select Fields.
2. Search for following fields:
   • tenant_name. This field is tagged at the collector level and you can get the tenant name using the instructions here.
   • location. The region to which the resource name belongs to.
   • subscription_id. ID associated with a subscription where resource is present.
   • resource_group. The resource group name where the Azure resource is present.
   • provider_name. Azure resource provider name (for example, Microsoft.WEB).
   • resource_type. Azure resource type (for example, SITES).
   • resource_name. The name of the resource (for example, Azure Function App name).
3. Create the fields if they are not present. Refer to Manage fields.

Configure Field Extraction Rules

Create a Field Extraction Rule (FER) by following the instructions here. If the FER already exists with same name, then skip this step.

Azure location extraction FER

Rule Name: AzureLocationExtractionFER
Applied at: Ingest Time
Scope (Specific Data): tenant_name=*

Parse Expression

json "location", "properties.resourceLocation", "properties.region" as location, resourceLocation, service_region nodrop
| replace(toLowerCase(resourceLocation), " ", "") as resourceLocation
| if (!isBlank(resourceLocation), resourceLocation, location) as location
| if (!isBlank(service_region), service_region, location) as location
| if (isBlank(location), "global", location) as location
| fields location

Resource ID extraction FER

Rule Name: AzureResourceIdExtractionFER
Applied at: Ingest Time
Scope (Specific Data): tenant_name=*

Parse Expression

json "resourceId", "ResourceId" as resourceId1, resourceId2 nodrop
| if (isBlank(resourceId1), resourceId2, resourceId1) as resourceId
| toUpperCase(resourceId) as resourceId
| parse regex field=resourceId "/SUBSCRIPTIONS/(?<subscription_id>[^/]+)" nodrop
| parse field=resourceId "/RESOURCEGROUPS/*/" as resource_group nodrop
| parse regex field=resourceId "/PROVIDERS/(?<provider_name>[^/]+)" nodrop
| parse regex field=resourceId "/PROVIDERS/[^/]+(?:/LOCATIONS/[^/]+)?/(?<resource_type>[^/]+)/(?<resource_name>.+)" nodrop
| parse regex field=resource_name "(?<parent_resource_name>[^/]+)(?:/PROVIDERS/[^/]+)?/(?<service_type>[^/]+)/?(?<service_name>.+)" nodrop
| if (isBlank(parent_resource_name), resource_name, parent_resource_name) as resource_name
| fields subscription_id, location, provider_name, resource_group, resource_type, resource_name, service_type, service_name

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 App Service Environment that you want to monitor.
   1. Choose Stream to an event hub as the destination.
   2. Select App Service Environment Platform Logs.
   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 Environment app

This section provides instructions on how to install the Azure App Service Environment 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 Environment 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.
