The server maintains many status variables that provide
information about its operation. You can view these variables and
their values by using the SHOW [GLOBAL | SESSION]
STATUS statement (see Section 13.7.5.36, “SHOW STATUS Syntax”).
The optional GLOBAL keyword aggregates the
values over all connections, and SESSION shows
the values for the current connection.

Many status variables are reset to 0 by the
FLUSH STATUS
statement.
The following table lists all available server status variables:
Table 5.5. Status Variable Summary
The status variables have the following meanings.
The number of connections that were aborted because the client died without closing the connection properly. See Section C.5.2.11, “Communication Errors and Aborted Connections”.
The number of failed attempts to connect to the MySQL server. See Section C.5.2.11, “Communication Errors and Aborted Connections”.
For additional connection-related information, check the
Connection_errors_status variables and thexxxhost_cachetable.The number of transactions that used the temporary binary log cache but that exceeded the value of
binlog_cache_sizeand used a temporary file to store statements from the transaction.The number of nontransactional statements that caused the binary log transaction cache to be written to disk is tracked separately in the
Binlog_stmt_cache_disk_usestatus variable.The number of transactions that used the binary log cache.
The number of nontransaction statements that used the binary log statement cache but that exceeded the value of
binlog_stmt_cache_sizeand used a temporary file to store those statements.The number of nontransactional statements that used the binary log statement cache.
The number of bytes received from all clients.
The number of bytes sent to all clients.
The
Com_statement counter variables indicate the number of times eachxxxxxxstatement has been executed. There is one status variable for each type of statement. For example,Com_deleteandCom_insertcountDELETEandINSERTstatements, respectively. However, if a query result is returned from query cache, the server increments theQcache_hitsstatus variable, notCom_select. See Section 8.9.3.4, “Query Cache Status and Maintenance”.All of the
Com_stmt_variables are increased even if a prepared statement argument is unknown or an error occurred during execution. In other words, their values correspond to the number of requests issued, not to the number of requests successfully completed.xxxThe
Com_stmt_status variables are as follows:xxxCom_stmt_prepareCom_stmt_executeCom_stmt_fetchCom_stmt_send_long_dataCom_stmt_resetCom_stmt_close
Those variables stand for prepared statement commands. Their names refer to the
COM_command set used in the network layer. In other words, their values increase whenever prepared statement API calls such as mysql_stmt_prepare(), mysql_stmt_execute(), and so forth are executed. However,xxxCom_stmt_prepare,Com_stmt_executeandCom_stmt_closealso increase forPREPARE,EXECUTE, orDEALLOCATE PREPARE, respectively. Additionally, the values of the older statement counter variablesCom_prepare_sql,Com_execute_sql, andCom_dealloc_sqlincrease for thePREPARE,EXECUTE, andDEALLOCATE PREPAREstatements.Com_stmt_fetchstands for the total number of network round-trips issued when fetching from cursors.Com_stmt_reprepareindicates the number of times statements were automatically reprepared by the server after metadata changes to tables or views referred to by the statement. A reprepare operation incrementsCom_stmt_reprepare, and alsoCom_stmt_prepare.Whether the client connection uses compression in the client/server protocol.
These variables provide information about errors that occur during the client connection process. They are global only and represent error counts aggregated across connections from all hosts. These variables track errors not accounted for by the host cache (see Section 8.11.5.2, “DNS Lookup Optimization and the Host Cache”), such as errors that are not associated with TCP connections, occur very early in the connection process (even before an IP address is known), or are not specific to any particular IP address (such as out-of-memory conditions). These variables were added in MySQL 5.6.5.
The number of errors that occurred during calls to
accept()on the listening port.The number of connections refused due to internal errors in the server, such as failure to start a new thread or an out-of-memory condition.
Connection_errors_max_connectionsThe number of connections refused because the server
max_connectionslimit was reached.The number of errors that occurred while searching for connecting client IP addresses.
The number of errors that occurred during calls to
select()orpoll()on the listening port. (Failure of this operation does not necessarily means a client connection was rejected.)The number of connections refused by the
libwraplibrary.
The number of connection attempts (successful or not) to the MySQL server.
The number of internal on-disk temporary tables created by the server while executing statements.
If an internal temporary table is created initially as an in-memory table but becomes too large, MySQL automatically converts it to an on-disk table. The maximum size for in-memory temporary tables is the minimum of the
tmp_table_sizeandmax_heap_table_sizevalues. IfCreated_tmp_disk_tablesis large, you may want to increase thetmp_table_sizeormax_heap_table_sizevalues. value to lessen the likelihood that internal temporary tables in memory will be converted to on-disk tables.You can compare the number of internal on-disk temporary tables created to the total number of internal temporary tables created by comparing the values of the
Created_tmp_disk_tablesandCreated_tmp_tablesvariables.See also Section 8.4.3.3, “How MySQL Uses Internal Temporary Tables”.
How many temporary files mysqld has created.
The number of internal temporary tables created by the server while executing statements.
You can compare the number of internal on-disk temporary tables created to the total number of internal temporary tables created by comparing the values of the
Created_tmp_disk_tablesandCreated_tmp_tablesvariables.See also Section 8.4.3.3, “How MySQL Uses Internal Temporary Tables”.
Each invocation of the
SHOW STATUSstatement uses an internal temporary table and increments the globalCreated_tmp_tablesvalue.The number of rows written with
INSERT DELAYEDfor which some error occurred (probablyduplicate key).The number of
INSERT DELAYEDhandler threads in use for nontransactional tables.The number of
INSERT DELAYEDrows written to nontransactional tables.The number of times the server flushes tables, whether because a user executed a
FLUSH TABLESstatement or due to internal server operation. It is also incremented by receipt of aCOM_REFRESHpacket. This is in contrast toCom_flush, which indicates how manyFLUSHstatements have been executed, whetherFLUSH TABLES,FLUSH LOGS, and so forth.The number of internal
COMMITstatements.The number of times that rows have been deleted from tables.
The server increments this variable for each call to its
external_lock()function, which generally occurs at the beginning and end of access to a table instance. There might be differences among storage engines. This variable can be used, for example, to discover for a statement that accesses a partitioned table how many partitions were pruned before locking occurred: Check how much the counter increased for the statement, subtract 2 (2 calls for the table itself), then divide by 2 to get the number of partitions locked. This variable was added in MySQL 5.6.2.The number of times the server uses a storage engine's own Multi-Range Read implementation for table access. This variable was added in MySQL 5.6.1.
A counter for the prepare phase of two-phase commit operations.
The number of times the first entry in an index was read. If this value is high, it suggests that the server is doing a lot of full index scans; for example,
SELECT col1 FROM foo, assuming thatcol1is indexed.The number of requests to read a row based on a key. If this value is high, it is a good indication that your tables are properly indexed for your queries.
The number of requests to read the last key in an index. With
ORDER BY, the server will issue a first-key request followed by several next-key requests, whereas with WithORDER BY DESC, the server will issue a last-key request followed by several previous-key requests. This variable was added in MySQL 5.6.1.The number of requests to read the next row in key order. This value is incremented if you are querying an index column with a range constraint or if you are doing an index scan.
The number of requests to read the previous row in key order. This read method is mainly used to optimize
ORDER BY ... DESC.The number of requests to read a row based on a fixed position. This value is high if you are doing a lot of queries that require sorting of the result. You probably have a lot of queries that require MySQL to scan entire tables or you have joins that do not use keys properly.
The number of requests to read the next row in the data file. This value is high if you are doing a lot of table scans. Generally this suggests that your tables are not properly indexed or that your queries are not written to take advantage of the indexes you have.
The number of requests for a storage engine to perform a rollback operation.
The number of requests for a storage engine to place a savepoint.
The number of requests for a storage engine to roll back to a savepoint.
The number of requests to update a row in a table.

InnoDBbuffer pool that are busy because they have been allocated for administrative overhead, such as row locks or the adaptive hash index. This value can also be calculated asInnodb_buffer_pool_pages_total–Innodb_buffer_pool_pages_free–Innodb_buffer_pool_pages_data.Innodb_buffer_pool_pages_totalThe total size of the
InnoDBbuffer pool, in pages.The number of pages read into the

InnoDBbuffer pool by the read-ahead background thread that were subsequently evicted without having been accessed by queries.Innodb_buffer_pool_read_requestsThe number of logical read requests made to the
InnoDBbuffer pool. These requests could be serviced by returning data that was already in memory, or by reading the data from disk into memory first.The number of logical reads that
InnoDBcould not satisfy from the buffer pool, and had to read directly from disk.Normally, writes to the
InnoDBbuffer pool happen in the background. WhenInnoDBneeds to read or create a page and no clean pages are available,InnoDBflushes some dirty pages first and waits for that operation to finish. This counter counts instances of these waits. Ifinnodb_buffer_pool_sizehas been set properly, this value should be small.Innodb_buffer_pool_write_requestsThe number of writes done to the
InnoDBbuffer pool.The number of
fsync()operations so far. The frequency offsync()calls is influenced by the setting of theinnodb_flush_methodconfiguration option.The current number of pending

MyISAMkey cache.The number of physical reads of a key block from disk into the
MyISAMkey cache. IfKey_readsis large, then yourkey_buffer_sizevalue is probably too small. The cache miss rate can be calculated asKey_reads/Key_read_requests.The number of requests to write a key block to the
MyISAMkey cache.The number of physical writes of a key block from the
MyISAMkey cache to disk.The total cost of the last compiled query as computed by the query optimizer. This is useful for comparing the cost of different query plans for the same query. The default value of 0 means that no query has been compiled yet. The default value is 0.
Last_query_costhas session scope.The
Last_query_costvalue can be computed accurately only for simple “flat” queries, not complex queries such as those with subqueries orUNION. For the latter, the value is set to 0.The number of iterations the query optimizer made in execution plan construction for the previous query.

Currently, this variable is unused for the same reasons as described forTc_log_max_pages_used.For the memory-mapped implementation of the recovery log, this variable increments each time the server was not able to commit a transaction and had to wait for a free page in the log. If this value is large, you might want to increase the log size (with the

The number of seconds since the most recent
FLUSH STATUSstatement.

Reading the explanation for Handler read rnd next , I question it! I list some number from a test db that does almost all accesses by locating a record with a key (GE or xxx%) and then using next to access related record; yet the Handler read rnd next is relatively large.
Handler read key 42053
Handler read next 453703
Handler read rnd 696
Handler read rnd next 104378
On MySQL 5.0 the com_* variables of 'show status' are counted for the current connection only. The new undocumented command 'show global status' shows server-wide counters. (http://bugs.mysql.com/bug.php?id=19422)
In version 4.0.17, the explanation to Handler_ is different:
Example:
Handler_delete:
The number of times a row was deleted from a table.
Handler_update
The number of requests to update a row in a table.
Handler_write
The number of requests to insert a row in a table.
Could this be a typo for Handler_delete? Because requests and rows updated/deleted/inserted are different concept.
Sheila
There's a bug in 5.0.36 (and likely surrounding versions) for Handler_write: it increases by one every time a row from SHOW STATUS is displayed:
1 row in set (0.00 sec)------
mysql> FLUSH STATUS;
Query OK, 0 rows affected (0.00 sec)
mysql> SHOW GLOBAL STATUS; SHOW SESSION STATUS;
[...] 224 rows in set (0.01 sec)
[...] 224 rows in set (0.01 sec)
mysql> SHOW SESSION STATUS LIKE 'Handler_write';
------
Given the bug for Handler_write it is not possible to find out how many rows were inserted in this version, unless you use a workaround:
Rows_inserted= Handler_write - (number of times SHOW STATUS was run * number of rows SHOW STATUS displayed)
This could be programmed further using the Com_show_status variable:
--------
mysql> SHOW SESSION STATUS LIKE 'Com_show_status';
1 row in set (0.00 sec)
--------
So, on a system/version that had 224 rows in SHOW STATUS (please check), the workaround formula would be:
Rows_inserted=Handler_write-(Com_show_status * 224)
Note though that this workaround does not work when using partial SHOW STATUS statements (using LIKE etc) from time to time.
