Server Status Variables
533
The number of SSL session cache misses.
•
Ssl_session_cache_mode
[533]
The SSL session cache mode.
•
Ssl_session_cache_overflows
[533]
The number of SSL session cache overflows.
•
Ssl_session_cache_size
[533]
The SSL session cache size.
•
Ssl_session_cache_timeouts
[533]
The number of SSL session cache timeouts.
•
Ssl_sessions_reused
[533]
How many SSL connections were reused from the cache.
•
Ssl_used_session_cache_entries
[533]
How many SSL session cache entries were used.
•
Ssl_verify_depth
[533]
The verification depth for replication SSL connections.
•
Ssl_verify_mode
[533]
The verification mode for replication SSL connections.
•
Ssl_version
[533]
The SSL protocol version of the connection.
•
Table_locks_immediate
[533]
The number of times that a request for a table lock could be granted immediately.
•
Table_locks_waited
[533]
The number of times that a request for a table lock could not be granted immediately and a wait was
needed. If this is high and you have performance problems, you should first optimize your queries,
and then either split your table or tables or use replication.
•
Tc_log_max_pages_used
[533]
For the memory-mapped implementation of the log that is used by
mysqld
when it acts as
the transaction coordinator for recovery of internal XA transactions, this variable indicates
the largest number of pages used for the log since the server started. If the product of
Tc_log_max_pages_used
[533]
and
Tc_log_page_size
[533]
is always significantly less
than the log size, the size is larger than necessary and can be reduced. (The size is set by the
--
log-tc-size
[413]
option. Currently, this variable is unused: It is unneeded for binary log-based
recovery, and the memory-mapped recovery log method is not used unless the number of storage
engines capable of two-phase commit is greater than one. (
InnoDB
is the only applicable engine.)
Added in MySQL 5.0.3.
