Informational counters

Monitor TLS/SSL hardware acceleration performance and interpret KEY counter values, such as PRIV_KEY_RECV and SECU_PARAM_RECV, to assess system load and connection activity using the show counters command.

If a system under load is working well, you should see large counts for the following counters. Because there are two sides to the tracker process per connection, you can see these counters increase by two per connection. The PRIV_KEY_RECV and SECU_PARAM_RECV counters are the most important, and are highlighted. The CONTEXT_CREATED and CONTEXT_DESTROYED counters relate to the allocation of cryptographic chip memory.
