The first date for which the SSL certificate is valid. 

• Ssl_session_cache_hits 

The number of SSL session cache hits. 

• Ssl_session_cache_misses 

The number of SSL session cache misses. 

• Ssl_session_cache_mode 

The SSL session cache mode. 

• Ssl_session_cache_overflows 

The number of SSL session cache overflows. 

• Ssl_session_cache_size 

The SSL session cache size. 

• Ssl_session_cache_timeouts 

The number of SSL session cache timeouts. 

• Ssl_sessions_reused 

How many SSL connections were reused from the cache. 

• Ssl_used_session_cache_entries 

How many SSL session cache entries were used. 

• Ssl_verify_depth 

The verification depth for replication SSL connections. 

• Ssl_verify_mode 

The verification mode used by the server for a connection that uses SSL. The value is a bitmask; bits are defined in the openssl/ssl.h  header file: 

# define SSL_VERIFY_NONE 0x00 # define SSL_VERIFY_PEER 0x01 # define SSL_VERIFY_FAIL_IF_NO_PEER_CERT 0x02 # define SSL_VERIFY_CLIENT_ONCE 0x04 

SSL_VERIFY_PEER  indicates that the server asks for a client certificate. If the client supplies one, the server performs verification and proceeds only if verification is successful. SSL_VERIFY_CLIENT_ONCE indicates that a request for the client certificate is performed only in the initial handshake. 

• Ssl_version 

The SSL protocol version of the connection (for example, TLSv1). If the connection is not encrypted, the value is empty. 

• Table_locks_immediate 

The number of times that a request for a table lock could be granted immediately.
