  • CPU
    • Total CPU utilization
    • System CPU utilization
    • User CPU utilization
    • CPU utilization for I/O waiting
  • Physical memory
    • Total memory
    • Free memory
    • Used memory
    • Memory in PageCache
    • Memory in BufferCache
  • Disk
    • Total system disk space (bytes)
    • Free system disk space (bytes)
    • Used system disk space (bytes)
  • Load

    System load

  • Network traffic
    • Received network traffic (bytes)
    • Sent network traffic (bytes)
  • Network packets
    • Received network packets per minute
    • Sent network packets per minute
    • Received network errors per minute
    • Discarded network packets per minute

Go to the feature page

  1. Log on to the EDAS console.
  2. Go to the Application Overview page by using one of the following methods:
    • In the left-side navigation pane, choose Resource Management > Container Service Kubernetes Clusters or Resource Management > Serverless Kubernetes Clusters. In the top navigation bar, select a region. In the upper part of the page, select a microservice namespace. On the Container Service Kubernetes Clusters or Serverless Kubernetes Clusters page, click a cluster ID. In the Applications section of the Cluster Details page, click the name of the application that you want to manage.
    • In the left-side navigation pane, click Applications. In the top navigation bar, select a region. In the upper part of the page, select a microservice namespace. Select Container Service or Serverless Kubernetes Cluster from the Cluster Type drop-down list and click the name of the application that you want to manage.
  3. In the left-side navigation pane of the application details page, choose Monitor > Instance Details.
  4. In the left-side pane of the Instance Details page, select the instance that you want to view and click the HOST Monitoring tab on the right side of the page.

View host monitoring metrics

On the HOST Monitoring tab, you can view the time series curves in the CPU, Memory, Disk, Load, Network Traffic (Bytes), and Network Packets (Count) sections.

In each section, you can click the name of a metric, such as cpu_sys, to show or hide this metric in the chart.

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.
