 Analytics drives business value in IoT solutions, but not all analytics need to be in the cloud. Azure IoT Edge helps you bring the analytical power of the cloud closer to your devices to drive better business insights and enable offline decision making. For example, you can run anomaly detection at the edge to respond as quickly as possible to emergencies happening on a production line. If you want to reduce bandwidth costs and avoid transferring terabytes of raw data, you can clean and aggregate the data locally then only send the insights to the cloud for analysis.
 
-Azure IoT Edge brings edge-based capabilities to a cloud-based solution and is a feature of [Azure IoT Hub](../iot-hub/iot-concepts-and-iot-hub.md) that enables you to scale out and manage an IoT solution from the cloud.

 Both runtime modules create metrics that let you remotely monitor how an IoT Edge device or its individual modules perform. The IoT Edge agent reports on the state of individual modules and the host device, so it creates metrics like how long a module runs correctly, or the amount of RAM and percent of CPU used on the device. The IoT Edge hub reports on communications on the device, so it creates metrics like the total number of messages sent and received, or the time it takes to resolve a direct method. For the full list of available metrics, see [Access built-in metrics](how-to-access-built-in-metrics.md).
 
-Both modules automatically expose these metrics, so you can create your own solutions to access and report on them. To make this process easier, Microsoft provides the [azureiotedge-metrics-collector module](https://mcr.microsoft.com/en-us/artifact/mar/azureiotedge-metrics-collector/tags), which handles this process if you don't have or want a custom solution. The metrics collector module collects metrics from the two runtime modules and any other modules you want to monitor, and sends them off the device.

 The metrics collector module sends your metrics to the cloud in one of two ways. The first option, used in this tutorial, sends the metrics directly to Log Analytics. The second option is recommended only if your networking policies require it. It sends the metrics through IoT Hub and then sets up a route to pass the metric messages to Log Analytics. Either way, once the metrics are in your Log Analytics workspace, you can view them through Azure Monitor workbooks.
