Server Status Variables The first date for which the SSL certificate is valid. The number of SSL session cache hits. The number of SSL session cache misses. The SSL session cache mode. The number of SSL session cache overflows. The SSL session cache size. The number of SSL session cache timeouts. How many SSL connections were reused from the cache. How many SSL session cache entries were used. The verification depth for replication SSL connections. 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. The SSL protocol version of the connection (for example, TLSv1). If the connection is not encrypted, the value is empty. The number of times that a request for a table lock could be granted immediately. 968 • Table_locks_immediate • Ssl_version • Ssl_verify_mode • Ssl_verify_depth • Ssl_used_session_cache_entries • Ssl_sessions_reused • Ssl_session_cache_timeouts • Ssl_session_cache_size • Ssl_session_cache_overflows • Ssl_session_cache_mode • Ssl_session_cache_misses • Ssl_session_cache_hits
