Disk Metrics

After metric thresholds and alarming criteria related to disk usage are configured, alarming short messages or emails can be sent to technical support. In this way, technical support can detect and handle service exceptions in a timely manner to reduce the loss caused by exceptions. The following table lists the metrics related to disks used for BCS services.
