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.
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
