View ultra low latency usage with the Wowza Streaming Cloud REST API

Learn how to use the REST API to get usage data for an ultra low latency stream target in the Wowza Streaming Cloud™ service. Usage data includes bandwidth for each zone and protocol used by the stream target.

Note: Ultra low latency streaming is available through Wowza Streaming Cloud with Ultra Low Latency. For more information see About ultra low latency streaming with Wowza Streaming Cloud.

View network usage for an ultra low latency stream target

Network usage, also called bandwidth, is the amount of data that went through the Wowza Streaming Cloud ultra low latency stream target. To view usage for stream targets, call the resource

Example request and response

Notes:

• To authenticate API requests, use HMAC authentication for production environments. For testing or proof of concept purposes only, use API key and access key authentication.
• The curl examples below use environment variables. See Using cURL for more information on how to set these up.

curl -X GET \
-H "wsc-api-key: ${WSC_API_KEY}" \
-H "wsc-access-key: ${WSC_ACCESS_KEY}" \
"${WSC_HOST}/api/${WSC_VERSION}/usage/network/stream_targets"

The query returns details on usage for all stream targets during the specified timeframe. Usage for ultra low latency targets is listed by protocol. Ultra low latency usage is listed by the zone where the servers are located. See Ultra low latency zones for more information about zones. HLS streams have one zone, global.

Note: In v1.3 and earlier of the Wowza Streaming Cloud REST API, bytes_billed now returns a value of 0. Due to timing differences between usage and billing systems, the previous bytes_billed value didn't consistently reflect the number of bytes billed for in a billing cycle.

The response for ultra low latency usage looks something like this:
