Basic Metrics
The following are basic metrics for the namespace Virtual Server.
In the table below, metrics with metric names marked in bold are selected as key metrics among the basic metrics provided by Virtual Server. Key metrics are used to configure service dashboards that are automatically built for each service in ServiceWatch. You can also check key metrics on the monitoring tab of the Virtual Server detail page.
Each metric guides you on which statistic value is meaningful when querying that metric through the user guide, and the statistic value marked in bold among the meaningful statistics is the key statistic value. In the service dashboard or monitoring tab, you can view key metrics through key statistic values.
