+Shows the number of currently active sessions for your account. Unlike the `SessionCount` metric (a cumulative counter), this metric is a real-time gauge showing how many sessions are running at any given moment. Amazon Bedrock AgentCore publishes this metric once per minute per service type. Use it to monitor current capacity utilization, set alarms for unexpected usage spikes, and understand your session quota consumption. Use the `Service` dimension — with values `AgentCore.Runtime`, `AgentCore.CodeInterpreter`, or `AgentCore.Browser` — to filter this metric by workload type. Amazon Bedrock AgentCore publishes this metric directly to your AWS account in the `AWS/Bedrock-AgentCore` namespace.
