What Monitoring Metrics for an AS Group Will Be Affected If VM Tools Are Not Installed on the Instances in the Group?

If VM Tools have not been installed on ECS instances, Cloud Eye can monitor metrics Outband Incoming Rate and Outband Outgoing Rate. However, it cannot monitor metrics Memory Usage, Inband Incoming Rate, and Inband Outgoing Rate, which reduces data accuracy of CPU usage.

If the ECS instances are I/O-optimized, Cloud Eye cannot monitor metrics Disk Usage, Inband Incoming Rate, and Inband Outgoing Rate of instances no matter VM Tools are installed or not.

If VM Tools are not installed on ECS instances, AS cannot obtain the memory usage, inband incoming rate, and inband outgoing rate.
