π Excited to share insights from our recent work on building an oversaturation detector (OSD) using iterative error analysis! We began with a baseline algorithm that struggled with false alerts due to erratic initial data. By ignoring the first 25% of requests, we significantly reduced these errors. Next, we added a 30-second grace period to differentiate good runs from bad ones during the early shoot-up phase. Finally, we established a rule to alert only when both response time and request...
