Observe real-time data for nodes and interfaces on charts

This topic applies to all Orion Platform products except for the following products:

ETSIPAMUDTWPM

Starting with Orion Platform 2019.4, you can observe featured data in real time on the following charts:

  • CPU Load & Memory Usage - Real Time Data (Node Details view, Vital Stats)
  • Percent Utilization - Real Time Date (Interface Details view)

Observe real-time data on charts

  • To see CPU Load & Memory Usage, go to a node details view and click the Vital Stats subview.
  • To see Percent Utilization, open an interface details view.

    When you open a page with a real-time chart, real-time polling starts automatically. By default, the data is updated every two seconds.

    When you leave the page, real-time polling stops in 120 seconds.

    Real-time charts show data for a constant time frame of ten minutes. You cannot change the time frame.

I cannot see the real-time chart on my node/interface details page

If there is no data to display, real-time charts are not displayed.

  • Open the node in PerfStack. If you can see real-time data there, you should be able to see real-time data on the real-time chart.

  • Make sure the node/interface is monitored by the Orion Platform for a few minutes.

    Real-Time Data charts do not display immediately when you add the node/interface because the identification of real-time polling capabilities takes some time, usually it is around 5-10 minutes.

If there is data to display, an administrator might have removed the chart from the view. You can add the widget.

I cannot see both metrics on the real-time chart

If your devices do not support both charted metrics, real-time charts only display the data for the supported metric.

I want the charts to update less frequently.

Change the refresh time:

  1. Click Settings > All Settings, and then click Web Console Settings.
  2. Scroll down to Modern Chart Settings, and adjust the Real time charts refresh time.
