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

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

If the ECSs are of I/O-optimized type, Cloud Eye cannot monitor the disk usage, inband incoming rate, and inband outgoing rate metrics of ECSs, regardless of whether VM tools are installed.

If VM tools are not installed on ECSs, AS cannot obtain the memory usage, inband incoming rate, and inband outgoing rate.
