From 3877335d89b2f90eff47036c7f4a5a93ece15595 Mon Sep 17 00:00:00 2001 From: AHMET YILMAZ Date: Thu, 16 Oct 2025 16:48:13 +0800 Subject: [PATCH] Profiling/monitoring :Add interactive monitoring dashboard and integration tests for monitoring endpoints - Implemented an interactive monitoring dashboard in `demo_monitoring_dashboard.py` for real-time statistics, profiling session management, and system resource monitoring. - Created a quick test script `test_monitoring_quick.py` to verify the functionality of monitoring endpoints. - Developed comprehensive integration tests in `test_monitoring_endpoints.py` covering health checks, statistics, profiling sessions, and real-time streaming. - Added error handling and user-friendly output for better usability in the dashboard.
