Hi,
you can try iMC (Intelligent Management Center), it provides multi-vendor support, alarm management, configuration management, performance management etc. It works with Aruba CX devices (although there are some limitations in SNMP from Aruba CX side, which are bypassed using REST API). There is 60 days trial period of the tool, then you can buy license for it. Can be installed on Linux and Windows servers:
HPE Networking | Enterprise
HPE Networking | Enterprise
IMC has many other features, additional modules can be installed for deeper monitoring like traffic analysis, wireless management and many others.
Thank you,
Best Regards,
Ivaylo
