What Are the Impacts on ECS Metrics If VM Tools Are Not Installed on ECSs?

If VM Tools are not installed on your ECSs, Cloud Eye can still monitor the outband incoming rate and outband outgoing rate. However, it cannot monitor memory usage, disk usage, inband incoming rate, or inband outgoing rate, which reduces the CPU monitoring accuracy.

For details about ECS metrics supported by Cloud Eye, see Basic ECS Metrics.
