Monitoring links

By monitoring the links between devices, you can determine the status of the devices connected by the link. In addition, you can launch tools to diagnose the underlying problem.

Your administrator can configure links to display event information or link status information from poll policiesFix pack 11:. Links can be displayed as colored, or colored with an associated severity icon. They can also configure the thickness of the line based on the connection speed of the link. By default, these options are on.

The display of link status can be customized for each individual view.

  1. Open any view that displays the links between devices.
    An error status for a link is indicated by a line with a color corresponding to the alert status, as well as an associated severity status icon, if configured.
  2. Hover over the link to display information about the link.
  3. Click a link to select it.

    V4.2 Fix Pack 4: If IP SLA discovery has been configured, selecting a link displays the probes that are monitoring the link.

  4. Right-click a link to open the right-click menu.
From the right-click menu, you can do any of the following tasks:
  • Display the link events in the Event Viewer. If you change the severity status of an event in the Event Viewer, this status will be filtered back to the link.
  • Ping the link end points.
  • Diagnose an underlying problem. For example, you can ping the IP addresses either side of a link.
  • Unmanage the link and associated devices to prevent the devices at the link's end points from being polled. Typically, you would unmanage a link while maintenance is carried out, and then manage it again once it has been restored to working order.
    Note: When you unmanage a link, you unmanage all connected interfaces. This is indicated by half-spanner icons at each end of the link.
  • Manage the link and associated devices.
