[Azure Cache for Redis](https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-overview) provides an in-memory data store based on the Redis software. It offers both the Redis open-source (OSS Redis) and a commercial product from Redis Inc. (Redis Enterprise) as a managed service. This integration helps in tracking cache performance (miss rate, latency, read and write rate) and monitor resource usage (CPU, used memory, server load, and connections) of your instances.

## Log and metric types

For Azure Cache for Redis, you can collect the following logs and metrics:

* **Connection logs**. These logs contains information about the connections to the cache for security and diagnostic purposes. To learn more about the [limitations of connection logging](https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-monitor-diagnostic-settings?tabs=basic-standard-premium#prerequisiteslimitations-of-connection-logging) and [schemas](https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-monitor-diagnostic-settings?tabs=basic-standard-premium#contents-of-the-connection-logs) collected for Azure Cache for Redis, refer to the Azure documentation.
* **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](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/activity-log-schema).
* **Cache Metrics**. These metrics are available in [Microsoft.Cache/redis](https://learn.microsoft.com/en-us/azure/azure-monitor/reference/supported-metrics/microsoft-cache-redis-metrics) and [Microsoft.Cache/redisEnterprise](https://learn.microsoft.com/en-us/azure/azure-monitor/reference/supported-metrics/microsoft-cache-redisenterprise-metrics) namespace. For more information on supported metrics, refer to the [Azure documentation](https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-how-to-monitor#list-of-metrics).

## 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/).
* Activity 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/). It is recommended to create a separate source for activity logs. If you are already collecting these logs, you can skip this step.
* 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 Cache for Redis 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/RedisCache/Logs` and `Azure/RedisCache/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. <br/><img src={useBaseUrl('img/integrations/microsoft-azure/Azure-Storage-Tag-Tenant-Name.png')} alt="Azure Tag Tenant Name" style={{border: '1px solid gray'}} width="500" />

### Configure metrics collection

import MetricsSource from '../../reuse/metrics-source.md';

<MetricsSource/>

### 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 the [Azure Event Hubs Source for Logs](/docs/send-data/collect-from-other-data-sources/azure-monitoring/ms-azure-event-hubs-source/).
2. To create the diagnostic settings in Azure portal, refer to the [Azure documentation](https://learn.microsoft.com/en-gb/azure/data-factory/monitor-configure-diagnostics). Perform the steps below for each azure redis cache account that you want to monitor.
   1. Choose **Stream to an event hub** as the destination.
   1. 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.
   <img src={useBaseUrl('img/send-data/azureredis-cache-logs.png')} alt="Azure Redis Cache logs" style={{border: '1px solid gray'}} width="800" /> 
3. Tag the location field in the source with right location value. <br/><img src={useBaseUrl('img/integrations/microsoft-azure/Azure-Storage-Tag-Location.png')} alt="Azure Redis Cache Tag Location" style={{border: '1px solid gray'}} width="500" />

#### Activity logs (optional)

import ActivityLogs from '../../reuse/apps/azure-activity-logs.md';

<ActivityLogs/>

## Installing the Azure Redis Cache app

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

import AppInstallIndexV2 from '../../reuse/apps/app-install-index-option.md';

<AppInstallIndexV2/>

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 to which 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).
