What Are the Effects on ECS Metrics If Vmtools Is Not Installed on ECSs?



If vmtools is not installed on ECSs, CES cannot monitor Memory Usage, Disk Usage, Inband Incoming Rate, and Inband Outgoing Rate of those ECSs. However, CES can monitor Outband Incoming Rate and Outband Outgoing Rate, reducing the data accuracy of CPU Usage.


If the ECSs are I/O-optimized ECSs, CES cannot monitor Disk Usage, Inband Incoming Rate, and Inband Outgoing Rate of ECSs no matter vmtools is installed or not.
