You can use the host monitoring feature to collect the data of the CPU, memory, disks, load, network traffic, and network packets. This topic describes the host monitoring feature and how to view host monitoring metrics.

Procedure

  1. Log on to the ARMS console. In the left-side navigation pane, choose Application Monitoring > Applications.
  2. On the Applications page, select a region in the top navigation bar and click the name of the application that you want to manage.
    Note If the Java icon icon is displayed in the Language column, the application is connected to Application Monitoring. If a hyphen (-) is displayed, the application is connected to Tracing Analysis.
  3. In the left-side navigation pane, click Application Details.
  4. On the Application Details page, click the HOST Monitoring tab.
    ARMS Application Monitoring - Application Details - HOST Monitoring

View host monitoring metrics

On the HOST Monitoring tab, you can view the time series curves of metrics that are related to the CPU, memory, disks, load, network traffic, and network packets.

  • You can click the name of a metric, such as the system CPU utilization, in a chart to show or hide the metric.
    Note Each chart must contain at least one visible metric. If only one metric is displayed in a chart, you cannot hide the metric.
  • You can click the line chart icon in the upper-right corner of a chart to view the metric trend in a specific time range, or compare metric trends in two time ranges.
  • You can click the View API icon in the upper-right corner of a chart to view the detailed information about the APIs that are related to the metrics.
  • In the upper-right corner of the monitoring panel, click the View Configured Alerts icon to create an alert rule or click the Create an alert rule icon to view the existing alert rules based on which alerts are generated. For more information about how to create an alert rule, see Create and manage an alert rule in Application Monitoring (new).
