Currently, we don't have any out-of-the-box solution for Cisco UCS monitoring.
We will consider this as a feature request and add it to our product roadmap. However, we can't commit an exact timeline on when this feature will be taken for development. We will update this thread once the feature is live with Site24x7.
As a workaround, we recommend you to use Site24x7 custom SNMP monitoring to monitor your individual switches and servers.
