 # memory bandwidth exporter
 
-Pod/container grained memory bandwidth exporter provides users memory bandwidth metrics of their running containers.  The metrics include llc_occupancy, mbm_local_bytes, mbm_total_bytes, cpu utilization and memory usage, and the metrics have been processed. In addition to container-level metrics, it also provides class-level and socket-level metrics. Users can configure the list of metrics to be collected. It serves as an exporter which can be connected to Promethus-like obserbility tools. And it also can be used as a telementry provider.

 Memory bandwidth exporter makes use of state-of-the-art technologies like NRI to build a resource-efficient and well-maintained solution. This solution provides observability to memory bandwidth to OPEA micro-services. It lays the groundwork of better scaling and auto scaling of OPEA. It can also be deployed separately on end user environments, supporting any cases that memory bandwidth metrics are required.
 
 ## Setup
 
 ### Enable NRI in Containerd
+
 ```sh
 # download containerd binary, containerd version v1.7.0 or higher is required
 $ wget https://github.com/containerd/containerd/releases/download/v1.7.0/containerd-1.7.0-linux-amd64.tar.gz

 ### Enable RDT
 
 Mount resctrl to the directory `/sys/fs/resctrl`:

 ```sh
 $ sudo mount -t resctrl resctrl /sys/fs/resctrl
