## FAQ

Q: Where can I view real-time CPU and memory usage for my ECS instance?
A: Go to the CloudMonitor console > Monitoring Charts, find your instance, and click the **Monitoring** button in the Monitoring column.

Q: What permissions are required to configure monitoring thresholds?
A: For instance-level thresholds, you need operations administrator privileges. For organization-level thresholds, you need admin access to the target organization.

Q: Can I modify monitoring thresholds after they are set?
A: Yes. Return to the Monitoring & Maintenance page, select the appropriate tab (High/Low Resource or Quota Usage), and click **Set Thresholds** again to update values.

Q: What happens if I leave the threshold fields blank?
A: Blank thresholds mean no filtering is applied. Only instances or organizations that meet the default or previously configured thresholds will appear in the lists.

Q: Are monitoring charts available for all ECS instance types?
A: Yes, basic monitoring metrics (CPU, memory, disk, network) are available for all running ECS instances through CloudMonitor without additional setup.
