CA Performance configuration change for Network Routers

Issue/Introduction

The current Filter configured for the Interface Metric Family included "does not equal tunnel(131)" which results in Tunnel interfaces Filtered out and not polled.

We want to remove it in order to prevent the filtering against Tunnel interfaces for select Devices. At the same time we want the filter to remain applied to all other devices.

We currently have the default "Network Interface" Monitoring Profile associated to the default "All Manageable Devices" Collection. These are not editable.

What is the way to make this change in order to ensure no data gap is seen for currently polled items from the Interface Metric Family?

Environment

All supported DX NetOps Performance Management releases

Resolution

Use the following steps to make the required change to the Metric Family Filter. This process can be used for making changes to other Metric Family Filter configurations. This process can be used to make the same changes to Metric Families other than the Interface Metric Family.

Following these steps will prevent a possible polling data gap.

1. Create a new Collection to store the devices that will no longer have the Tunnel interface types filtered out.
   • For this example we'll name the new Collection "Devices with Tunnel Interfaces"
2. Create a new Collection to store the devices that will continue to have the Tunnel interface types filtered out.
   • For this example we'll name the new Collection "Devices without Tunnel Interfaces"
3. Create a copy of the existing Monitoring Profile in use that houses the Interface Metric Family.
   1. For this example we'll assume use of the default "Network Interface" Monitoring Profile.
   2. Create a copy of the Monitoring Profile. For this example we'll name it "Network Interface with Tunnels".
   3. Edit the Interface Metric Family Component Filter to remove the part that's filtering out the Tunnel type interfaces.
4. Associate the following together:
   • Associate the new Collection "Devices with Tunnel Interfaces" to the new Monitoring Profile "Network Interface with Tunnels".
   • Associate the new Collection "Devices without Tunnel Interfaces" to the default "Network Interface" Monitoring Profile.
5. Break the association between the default "Network Interface" Monitoring Profile and the default "All Manageable Devices" Collection.

We'll now have:

• Devices that should have Tunnel Interfaces filtered out applied to the Monitoring Profile with Interface Metric Family that does filter those out.
  • Via the Collection "Devices without Tunnel Interfaces" association the default "Network Interface" Monitoring Profile.
• Devices that should NOT have Tunnel Interfaces filtered out applied to the Monitoring Profile with Interface Metric Family that does NOT filter those out.
  • Via the Collection "Devices with Tunnel Interfaces" to the new Monitoring Profile "Network Interface with Tunnels".
