Monitored CloudTable Metrics
Description
Monitoring is critical to ensure CloudTable reliability, availability, and performance. You can monitor the running status of CloudTable servers.
This section describes the metrics that can be monitored by Cloud Eye as well as their namespaces and dimensions. You can use the management console or APIs provided by Cloud Eye to query the metrics of the monitored objects and alarms generated for CloudTable.
