Being asked if it is possible to remove devices showing up in a Dashboard for MOS metric data that do not have voice configured.

A View is configured to show metric data in Ascending order. This shows the lowest values, the worst values, first.

There are devices that are discovered which support these metrics, MOS tests in this instance, but the device is disabled for these tests. As a result it's expected to see zero values for the related metrics.

When the View shows items in Ascending order, it lists those with the expected zero values first. This moves devices with real data, those with low values that require further review, below the zero values. They are somewhat hidden at first glance.


All supported DX NetOps Performance Management releases


The View is using All Groups. This will provide all devices that support the Views metrics.


There are two ways to resolve this.

  1. Create a custom Group that contains only the known devices that MOS data is expected from.
    • Ensure the Group DOES NOT contain the known devices where MOS tests are disabled, those we'd expect to see zero values from.
    • Edit the View and set the Context Settings to Fixed, selecting the new Group.
    • This is the simplest and easiest method to resolve this problem.
  2. Break the association between the Metric Family and the device.
    • This can be a more complex solution in most environments.
    • Careful consideration should be given to changing the devices Collection membership.
    • The same careful consideration should be given to changing the devices Monitoring Profile associations via it's Collection membership(s).
    • If making those changes ensure you're aware of any other Metric Family relationships that will be broken if those changes are made.
