Understanding the RTMP input health metrics is crucial for maintaining optimal streaming performance. This article will guide you through the key RTMP input metrics, what they mean, and how to respond if these metrics indicate potential issues.

You can find input health metrics on your Spalk Dashboard under the Stream Status dropdown for RTMP events.

Key Metrics

1. Network In
   
   
   • Description: This represents the rate at which data is being transferred into the streaming platform. It's a direct indicator of the quality and smoothness of your stream.
   • Troubleshooting: If the bitrate is lower than expected, it can lead to poor video quality. Ensure your network can handle the required bitrate for your stream's resolution and frame rate. Consider using a wired connection for stability.
2. Average Input Video Frame Rate
   
   
   • Description: This metric shows the average frame rate of the incoming video stream.
   • Troubleshooting: A frame rate lower than expected can indicate issues with the video source or network. Check the video source settings and ensure the network is stable.
3. Minimum Input Video Frame Rate
   
   
   • Description: This metric shows the minimum frame rate of the incoming video stream.
   • Troubleshooting: Consistently low minimum frame rates suggest intermittent issues with the video source or network. Ensure the video source is not overloaded and the network connection is robust.
4. Active Alerts
   
   
   • Description: This shows the number of active alerts on the MediaLive encoder each minute.
   • Troubleshooting: A high number of active alerts can indicate various issues with the encoder or input stream. Check the details of the alerts to diagnose and resolve specific problems.
5. Alert Details
   
   
   • Description: This provides detailed information about each alert generated by the MediaLive encoder.
   • Troubleshooting: Use this information to understand the specific issues affecting your stream. Common alerts may include connection problems, missing video or audio, and network instability. Address these issues as recommended by the alert details.
