View the host metrics

On the HOST Monitoring tab, you can view the time series curves for metrics that are related to the CPU, memory, disk, load, network traffic, and network packets.

  • You can click the name of a metric such as cpu_sys on a chart to show or hide the metric.
    Note Each chart must contain at least one visible metric. Therefore, if only one metric is displayed in a chart, you cannot hide this metric.
  • You can click the line chart icon in the upper-right corner of a chart to view the metrics by time range or compare the metrics.
  • You can click the View API icon in the upper-right corner of a chart to view the detailed information about the APIs that are related to the metrics.
  • You can click the 已配置报警点 or 创建报警icon in the upper-right corner of a chart to view the existing alerts or create an alert. For more information about how to create an alert, see Create an alert.
