[Azure Cosmos DB](https://learn.microsoft.com/en-us/azure/cosmos-db/introduction) is a fully managed NoSQL and relational database for modern app development offering single-digit millisecond response times, automatic and instant scalability, along with guaranteed speed at any scale. This integration helps in monitoring the overall performance, failures, capacity, and operational health of all your Azure Cosmos DB resources.
The below instructions applies to the following [database APIs](https://learn.microsoft.com/en-us/azure/cosmos-db/choose-api):
* NoSQL
* MongoDB
* Cassandra
* Gremlin
* Table
:::note
This app is tested with Azure Cosmos DB for MongoDB, Cassandra, and NoSQL database account types.

## Log and metric types
For Azure Cosmos DB, 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 Cosmos DB, refer to the [Azure documentation](https://learn.microsoft.com/en-us/azure/cosmos-db/monitor-reference#resource-logs).
* **Platform Metrics for Azure Cosmos DB**. For more information on supported metrics and dimensions, refer to the [Azure documentation](https://learn.microsoft.com/en-us/azure/cosmos-db/monitor-reference#metrics). These metrics are available within the namespace `Microsoft.DocumentDB/DatabaseAccounts`
* **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](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/activity-log-schema).
## Setup
Azure service sends monitoring data to Azure Monitor, which can then [stream data to Eventhub](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/stream-monitoring-data-event-hubs). Sumo Logic supports:
* Logs collection from [Azure Monitor](https://docs.microsoft.com/en-us/azure/monitoring-and-diagnostics/monitoring-get-started) using our [Azure Event Hubs source](/docs/send-data/collect-from-other-data-sources/azure-monitoring/ms-azure-event-hubs-source/).
* Metrics collection using our [Azure Metrics Source](/docs/send-data/hosted-collectors/microsoft-source/azure-metrics-source).
You must explicitly enable diagnostic settings for each Azure Cosmos DB account you want to monitor. You can forward logs to the same Event Hub provided they satisfy the limitations and permissions as described [here](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/diagnostic-settings?tabs=portal#destination-limitations).
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/CosmosDB/Logs`, `Azure/CosmosDB/Metrics`.
### Configure collector
Create a hosted collector if not already configured and tag the `tenant_name` field. You can get the tenant name using the instructions [here](https://learn.microsoft.com/en-us/azure/active-directory-b2c/tenant-management-read-tenant-name#get-your-tenant-name). Make sure you create the required sources in this collector.
### Configure metrics collection
import MetricsSource from '../../reuse/metrics-source.md';
### Configure logs collection
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](/docs/send-data/collect-from-other-data-sources/azure-monitoring/ms-azure-event-hubs-source/).
2. If you want to audit Azure Cosmos DB control plane operations, [disable the key based metadata write access](https://learn.microsoft.com/en-us/azure/cosmos-db/audit-control-plane-logs#disable-key-based-metadata-write-access).
3. To create the diagnostic settings in Azure portal, refer to the [Azure documentation](https://learn.microsoft.com/en-us/azure/cosmos-db/monitor-resource-logs?tabs=azure-portal#create-diagnostic-settings). Perform the following steps for each Azure Cosmos DB account that you want to monitor.
1. Choose **Stream to an event hub** as the destination.
1. Select your preferred log categories depending upon your database API or select **allLogs**.
1. 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.
4. Tag the location field in the source with right location value.
#### Activity logs (optional)
import ActivityLogs from '../../reuse/apps/azure-activity-logs.md';
##### Enabling Microsoft Defender for Cloud
For security events, make sure you enable [Microsoft Defender for Cloud](https://learn.microsoft.com/en-us/azure/defender-for-cloud/defender-for-databases-enable-cosmos-protections?tabs=azure-portal). In the Defender Plans Settings page toggle the Databases status under the Cloud Workload Protection section and select the resource types.
## Installing the Azure Cosmos DB app
This section provides instructions on how to install the Azure Cosmos DB app, and shows examples of each of the preconfigured dashboards you can use to analyze your data.
import AppInstallIndexV2 from '../../reuse/apps/app-install-index-option.md';
As part of the app installation process, the following fields will be created by default:
- `tenant_name`. This field is tagged at the collector level. You can get the tenant name using the instructions [here](https://learn.microsoft.com/en-us/azure/active-directory-b2c/tenant-management-read-tenant-name#get-your-tenant-name).
- `location`. The region the resource name belongs to.
- `subscription_id`. ID associated with a subscription where the resource is present.
- `resource_group`. The resource group name where the Azure resource is present.
- `provider_name`. Azure resource provider name (for example, Microsoft.Network).
- `resource_type`. Azure resource type (for example, storage accounts).
- `resource_name`. The name of the resource (for example, storage account name).
- `service_type`. Type of the service that can be accessed with an Azure resource.
- `service_name`. Services that can be accessed with an Azure resource (for example, in Azure Container Instances the service is Subscriptions).
