ECS Metrics
ECS metrics vary depending on ECS OSs and types. For details, see Table 1. √ indicates that the metric is supported, and x indicates that the metric is not supported.

The image based on which the target ECS is created must have OTC Tools installed (OTC Tools has been installed for public images by default). Otherwise, the Memory Usage and Disk Usage metrics are unavailable. For details about how to install the OTC Tools, visit https://github.com/UVP-Tools/UVP-Tools/.
Table 2 describes these ECS metrics.
The monitoring intervals for the following ECSs with raw monitoring metrics are as follows:
- KVM ECS: 5 minutes
