The downtime information might be useful for example for SLA providers who want to prove specific times of interface/port unavailability.

Starting with NPM 12.3, check the health of interfaces in the Health Summary widget and get more details on the Node Details - Interfaces subview.

In some areas, an interface being down does not directly impact Internet or intranet connectivity.

  1. Log in to the Orion Web Console.
  2. Navigate to the interface or node view, and consult the Interface Downtime resource.

    By default, the resource shows the interface status in the last 24 hours, each hour represented as a block in the appropriate color.

    To display downtime for all monitored interfaces on a node, add the Interface Downtime resource on the  node view.

  3. To see a detailed view of a problematic section, position your cursor on the graph.

Change the time period

By default, the resource displays downtime data for the last 24 hours, one block representing 1 hour. You can display any time frame within the stored history.

  1. Go to the Interface Downtime resource, and click Edit.
  2. Select Custom in the Downtime Period list, and specify the Beginning and End dates and times.
  3. When displaying longer time periods, you might need to change the time frame represented by one block. Select Custom in Display Settings, and provide a time period represented by one block.
  4. Click Submit.

Set the retention period for the interface downtime history

By default, interface status history is stored in the database for 7 days.

  1. Log in to the Orion Web Console as an administrator.
  2. Click Settings > All Settings in the menu bar.
  3. In the Thresholds & Polling grouping, click Polling Settings.
  4. Scroll down to Database Settings, and provide how long you want to keep interface status history in the database in the Downtime History Retention field. Enter a value in days, from 7 to 60 days.

Disable interface downtime monitoring

Monitoring interface downtime can affect the performance of SolarWinds NPM. To decrease the load, disable interface downtime monitoring. For periods where interface downtime was not monitored, the Interface Downtime resource shows gray blocks.

  1. Log in to the Orion Web Console as an administrator.
  2. Click Settings > All Settings in the menu bar.
  3. In the Thresholds & Polling grouping, click Polling Settings.
  4. Clear the Enable Downtime Monitoring box in the Network grouping.
  5. Click Submit.

Interface downtime will not be monitored anymore. Starting from now, the Downtime Monitoring resource will display the message "Downtime monitoring is disabled. To enable it, go to Polling Settings."

View interface health

  1. In the Orion Web Console, go to the Node Details view.
  2. On the Summary subview, review the Health Summary widget to get an overview of the status of interfaces on the node.


  3. On the Health Summary widget, click a status group number to go to the Interfaces subview, filtered by the selected group status. The Interfaces subview lists monitored interfaces on the selected device, including relevant details, such as in and out utilization, or any errors that happened in the last hour.
