+## Analysis: What patterns do you observe in resource utilization?
+Cpu utilization is low, while memory is moderately used by GUI apps. I/O and disk usage are normal for my workload now (no opened heavy tasks).
+
+## Reflection: How would you optimize resource usage based on your findings?
+If I needed more memory I would close some heavy GUI apps or switched to terminal mode (remove GUI completely or changed display protocol)

+## Website URL you chose to monitor

+
+## Screenshots of browser check configuration
+![browser](../screenshots/lab8/browser.png)
+
+## Screenshots of successful check results
+![1](../screenshots/lab8/1.png)
+
+![dashboard](../screenshots/lab8/res.png)
+
+## Screenshots of alert settings
+
+![alert](../screenshots/lab8/alert.png)
+
+## Analysis: Why did you choose these specific checks and thresholds?
+
+I choose loading logo as browser check as a marker that indicates moodle successfully loads images. As for alert thresholds, I loosened them down, since IU moodle is known by its instability.
+
+## Reflection: How does this monitoring setup help maintain website reliability?
+
+Detects failures early and triggers alerts so incidents are noticed. That reduces time for repair. Also collects downtime stats and test logs which can be useful for fixing and debugging.
