## Performance Manager Collections

If you are managing your switches with the Performance Manager, you must set up an initial set of flows and collections on the switch. You can use Cisco DCNM Web Client to add and remove performance collections. The switch has to be licensed and in the Managed Continuously state before a collection for the switch can be created.

To add a collection follow these steps:

1. From the menu bar, click Admin>Collections.

2. Under Generate a threshold event when traffic exceeds % of capacity, use the checkbox to specify the Critical at and Warning at values. User can also use the For ISL/Trunk Only checkbox to limit the threshold events generated to ISL and Trunk events only and then click Apply.

3. In the Licensed Fabrics panel, use the checkboxes to select the Fabric, ISLs/NPV Links, Hosts, Storage, FC Flows and FC Ethernet to enable performance collection for these data types.

4. In the Licensed LAN Switches panel, use the checkboxes to enable performance data collection for Trunks, Access and Errors & Discards.

5. Use the checkboxes to select the type(s) of LAN switches for which you want to collect performance data.

6. Click Apply to save the configuration.

7. In the confirmation dialog box, click Yes to restart the performance collector.
