After modeling Cisco APIC devices in Spectrum, the Memory in the Thresholds subview of the model shows "None" for the Source. The performance tab shows "Invalid Value" for Memory.
Any version of Spectrum running on any supported operating system
Out of the box, Spectrum uses the information in the associated Cisco_Mem_App model to collect and display the memory information from the Cisco APIC device. However, the Ciscp APIC device does not support the required Cisco Memory mibs so the Cisco_Mem_App model is not created.
