Traffic between the HDS Nodes and the Cloud
Outbound Metrics Collection Traffic
The Hybrid Data Security nodes send certain metrics to the Cisco Webex cloud. These include system metrics for heap max, heap used, CPU load, and thread count; metrics on synchronous and asynchronous threads; metrics on alerts involving a threshold of encryption connections, latency, or a request queue length; metrics on the datastore; and encryption connection metrics. The nodes send encrypted key material over an out-of-band (separate from the request) channel.
Inbound Traffic
The Hybrid Data Security nodes receive the following types of inbound traffic from the Cisco Webex cloud:
-
Encryption requests from clients, which are routed by the encryption service
-
Upgrades to the node software
