ServiceWatch metric
You can view Virtual Server metrics in ServiceWatch for servers created in Cloud Hadoop. Like Virtual Server, the metrics provided by default monitoring are data collected at 5‑minute intervals. In the Virtual Server detailed view, enabling detailed monitoring allows you to view data collected at 1‑minute intervals. For more details, Virtual Server > Enable ServiceWatch Detailed Monitoring
- The basic monitoring and detailed monitoring of Cloud Hadoop are provided with the same metrics as Virtual Server, and the namespace is also provided as Virtual Server.
Basic Metrics
The following are the basic metrics for the Virtual Server namespace.
The indicators whose names are displayed in bold below are the key indicators selected from the basic metrics provided by Virtual Server. Key metrics are used to build service dashboards that are automatically created for each service in ServiceWatch.
Each metric provides guidance in the user guide on which statistical value is meaningful when viewing that metric, and among the meaningful statistics, the values shown in bold are the primary statistics. In the service dashboard, you can view key metrics using primary statistical values.
