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

Features

The host monitoring feature can be used to monitor the following metrics:

  • CPU
    • Total CPU utilization
    • System CPU utilization
    • User CPU utilization
    • CPU utilization for I/O waiting
  • 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 packet
    • Received network packets per minute
    • Sent network packets per minute
    • Received network errors per minute
    • Discarded network packets per minute

Procedure

  1. Log on to the EDAS console.
  2. Perform one of the following operations as needed to go to the application details page:
    • 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 namespace. On the Container Service Kubernetes Cluster or Serverless Kubernetes Clusters page, click a cluster ID. In the Applications section of the Cluster Details page, click the name of the application for which you want to view the details.
    • 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 namespace. Select Container Service or Serverless Kubernetes Cluster from the Cluster Type drop-down list and click the application name.
  3. In the left-side navigation pane of the application details page, choose Monitor > Instance Details.
  4. On the Instance Details page, select the node you want to view, and click the HOST Monitoring tab on the right side.

View host monitoring metrics

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

In each section, you can click the name of a metric such as cpu_sys to toggle the visibility of this metric.

Note Each chart must contain at least one visible metric. Therefore, if only one metric is displayed in a chart, you cannot disable the visibility of this metric.
