The host monitoring feature is used to monitor the metrics of CPU, memory, disk, load, network traffic, and network packets. This topic describes the host monitoring feature and how to view host monitoring metrics.

Feature description

The host monitoring feature can monitor the following metrics:

  • CPU
    • Total CPU usage
    • System CPU usage
    • User CPU usage
    • Usage of CPU waiting for I/O
  • Memory
    • Total 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
    • Received network traffic (bytes)
    • Sent network traffic (bytes)
  • Network packets
    • Received packets per minute
    • Sent packets per minute
    • Received errors per minute
    • Discarded packets per minute

Procedure

  1. Log on to the EDAS console.
  2. In the left-side navigation pane, click Applications.
  3. On the Applications page, select a region in the top navigation bar and a namespace from the Namespace drop-down list. Select ECS Clusters from the Cluster Type drop-down list, and then click the name of the application whose metrics you want to view.
  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.
    Application Monitoring > Application Details > HOST Monitoring

View host monitoring metrics

On the HOST Monitoring tab, you can view the time curves of 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 enable or disable 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, the metric 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 that are related to the metric.
