<p>The article announces that Amazon EventBridge now supports 22 additional Amazon CloudWatch metrics for event buses, enabling better monitoring of event bus performance and helping identify when service quotas need to be increased.</p>
<p>Specifically, the article covers:</p>
<ul>
<li>New CloudWatch metrics for event publishing, including API latency, event payload size, and counts of successful, failed, and throttled events.</li>
<li>New metrics for event invocations (when EventBridge delivers events to targets like AWS Lambda), providing visibility into retries, throttling, and end-to-end latency.</li>
<li>Benefits of these new metrics, such as deeper insight into event-driven applications and easier identification and resolution of issues.</li>
<li>Availability of the new metrics at no additional cost in several AWS regions, with more regions to follow.</li>
