  • CPU
    • Total CPU usage
    • System CPU usage
    • User CPU usage
    • Usage of CPU waiting for I/O
  • Memory

    • Free memory
    • Used memory
    • Memory in PageCache
    • Memory in BufferCache
  • Disk
    • Total disk space (bytes)
    • Free disk space (bytes)
    • Used disk space (bytes)
  • Load

    System load

  • Network traffic

View host monitoring metrics

  1. Log on to the EDAS console.
  2. In the left-side navigation pane, choose Application Management > Applications.
  3. On the Applications page, select a region and a namespace, and then click the name of the application you want to monitor.
  4. In the left-side navigation pane, choose Application Monitoring > Application Details.
  5. On the Application Details page, click the node that you want to view, and then click the HOST Monitoring tab on the right side.

    On the HOST Monitoring tab, you can view the time sequence curves of metrics including CPU, memory, disk, load, network traffic, and network packets.

    • You can click the name of a metric such as cpu_sys on each monitoring panel to toggle the visibility of this metric.
      Note Each chart must contain at least one visible metric. Therefore, if only one metric is displayed on a monitoring panel, it cannot be set to invisible.
    • You can click the line chart icon in the upper-right corner to view the metrics by range or compare the metrics.
    • You can click the View API icon in the upper-right corner to view the detailed information about the API operations related to the metric.
    • You can click the or icon in the upper-right corner of the monitoring panel to create an alert or view the existing alert points. For more information about how to create an alert, see Create an alert.
