AWS Elemental MediaTailor's transcoding performance, crucial for dynamically inserting relevant advertisements into media streams, poses a challenge in measurement due to the absence of traditional latency metrics. The solution involves leveraging Coralogix's log analytics and tools like the TCO Optimizer and DataPrime, allowing for cost-effective log processing and advanced querying without traditional indexing. By integrating MediaTailor logs into Coralogix and utilizing the Events2Metrics and DataPrime querying language, users can analyze transcoding events and calculate lead times using Little’s Law. Additionally, the platform enables the creation of visualizations and alerts to monitor transcoding performance, providing powerful insights and allowing users to explore various data-driven directions, such as throughput calculations and custom dashboards.
