The application monitoring function of Application Real-Time Monitoring Service (ARMS) provides the host monitoring function. It monitors metrics such as the CPU, memory, disk, load, network traffic, and network data packets. This topic describes the host monitoring feature and how to view host monitoring metrics.

Features

Host monitoring helps you monitor the following metrics.

  • CPU
    • SystemCpuIdle: idle CPU usage in the last five seconds
    • SystemCpuSystem: system CPU usage in the last five seconds
    • SystemCpuUser: user CPU usage in the last five seconds
    • SystemCpuIOWait: I/O await CPU usage in the last five minutes
  • Memory
    • SystemMemFree: idle system memory (in KB)
    • SystemMemTotal: total system memory (in KB)
    • SystemMemUsed: used system memory (in KB)
    • SystemMemBuffers: current memory in the cache of system buffer (in KB)
    • SystemMemCached: current memory in the cache of system page (in KB)
    • SystemMemSwapFree: idle memory of system swap (in KB)
    • SystemMemSwapTotal: total memory of system swap (in KB)
  • Disk
    • SystemDiskTotal: total bytes of the system disk
    • SystemDiskFree: idle bytes of the system disk
    • SystemDiskUsedRatio: usage of system disk
  • Load
    • SystemLoad: load on the system
  • Network traffic
    • SystemNetInBytes: average bytes per second received through the network in the last 30 seconds
    • SystemNetInErrs: average errors per second received through the network in the last 30 seconds
    • SystemNetOutBytes: average bytes per second sent through the network in the last 30 seconds
    • SystemNetOutErrs: average errors per second sent through the network in the last 30 seconds
  • Network packets
    • SystemNetInPackets: average messages per second received through the network in the last 30 seconds
    • SystemNetOutPackets: average messages per second sent through the network in the last 30 seconds

Procedure

  1. Log on to the ARMS console. In the left-side navigation pane, choose Application Monitoring > Applications.
  2. On the Applications page, click the name of the target application.

  3. On the Application Details page, select the target node and click the Host Monitoring tab on the right side of the page.

    The Host Monitoring tab shows the time sequence curves of the CPU, memory, disk, load, network traffic, and network packets.

    • You can enable or disable the visibility of a metric in the chart by clicking its name (for example, the system CPU usage) on the monitoring panel.
      Note Each chart must have at least one visible metric.
    • Click the two alert icons in the upper-right corner of the monitoring panel. You can view existing alert points and create new alerts. For how to create alerts, see Quickly create ARMS alerts.
