# Enable metric streaming

Metrics for managed resources can be streamed at a specified interval. You can do the following steps to enable the metric relay:

Enabling metric streaming APIs using REST APIs
Get list of resource types and metrics that can be configured for live streaming. `GET /rest/metrics/capability` Configure the live metric stream. `PUT /rest/metrics/configuration` Receive the live stream of metrics on AMQP message exchange – MSMB `msmb`

| NOTE: MSMB (Metric Streaming Message Bus) is an interface that uses asynchronous messaging to notify subscribers about the most recent metric of the managed resources. Metrics are streamed for servers with ILO Advanced Licenses only. Supported servers are G7, Gen 8, and Gen 9.
