Begin Variabelen Waarde Beschrijving
Flush_commands 1 The number of executed FLUSH statements.
Slow_queries 21 The number of queries that have taken more than long_query_time seconds. MySQL - Documentatie
Begin Handler Variabelen Waarde Beschrijving
Handler_commit 58 The number of internal COMMIT statements.
Handler_delete 24 k The number of times a row was deleted from a table.
Handler_discover 0 The MySQL server can ask the NDB Cluster storage engine if it knows about a table with a given name. This is called discovery. Handler_discover indicates the number of time tables have been discovered.
Handler_read_first 8.258 The number of times the first entry was read from an index. If this is high, it suggests that the server is doing a lot of full index scans; for example, SELECT col1 FROM foo, assuming that col1 is indexed.
***************************************
DEZE ONDERSTAANDE WAARDE???
Handler_read_key 14 M The number of requests to read a row based on a key. If this is high, it is a good indication that your queries and tables are properly indexed.
Handler_read_next 68 M The number of requests to read the next row in key order. This is incremented if you are querying an index column with a range constraint or if you are doing an index scan.
Handler_read_prev 15 k The number of requests to read the previous row in key order. This read method is mainly used to optimize ORDER BY ... DESC.
Handler_read_rnd 381 k The number of requests to read a row based on a fixed position. This 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 whole tables or you have joins that don't use keys properly.
Handler_read_rnd_next 151 M The number of requests to read the next row in the data file. This 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.
Handler_rollback 1.033 The number of internal ROLLBACK statements.
Handler_update 248 k The number of requests to update a row in a table.
Handler_write 26 M The number of requests to insert a row in a table.
Begin Query cache Variabelen Waarde Beschrijving
Flush query cache MySQL - Documentatie
Qcache_free_blocks 166 The number of free memory blocks in query cache.
Qcache_free_memory 37 M The amount of free memory for query cache.
***********************************************************
Qcache_hits 247 k The number of cache hits.
Qcache_inserts 48 k The number of queries added to the cache.
Qcache_lowmem_prunes 0 The number of queries that have been removed from the cache to free up memory for caching new queries. This information can help you tune the query cache size. The query cache uses a least recently used (LRU) strategy to decide which queries to remove from the cache.
Qcache_not_cached 3.111 The number of non-cached queries (not cachable, or not cached due to the query_cache_type setting).
Qcache_queries_in_cache 23 k The number of queries registered in the cache.
Qcache_total_blocks 47 k The total number of blocks in the query cache.
Begin Threads Variabelen Waarde Beschrijving
Laat processen zien MySQL - Documentatie
Slow_launch_threads 0 The number of threads that have taken more than slow_launch_time seconds to create.
Threads_cached 8 The number of threads in the thread cache. The cache hit rate can be calculated as Threads_created/Connections. If this value is red you should raise your thread_cache_size.
Threads_connected 4 The number of currently open connections.
Threads_created 12 The number of threads created to handle connections. If Threads_created is big, you may want to increase the thread_cache_size value. (Normally this doesn't give a notable performance improvement if you have a good thread implementation.)
Threads_running 1 The number of threads that are not sleeping.
Threads_cache_hitrate_% 99,89 %
Begin Binaire log Variabelen Waarde Beschrijving
MySQL - Documentatie
Binlog_cache_disk_use 0 The number of transactions that used the temporary binary log cache but that exceeded the value of binlog_cache_size and used a temporary file to store statements from the transaction.
Binlog_cache_use 0 The number of transactions that used the temporary binary log cache.
Begin Temporary data Variabelen Waarde Beschrijving
Created_tmp_disk_tables 426 The number of temporary tables on disk created automatically by the server while executing statements. If Created_tmp_disk_tables is big, you may want to increase the tmp_table_size value to cause temporary tables to be memory-based instead of disk-based.
Created_tmp_files 2.153 How many temporary files mysqld has created.
Created_tmp_tables 4.572 The number of in-memory temporary tables created automatically by the server while executing statements.
Begin Delayed inserts Variabelen Waarde Beschrijving
Delayed_errors 0 The number of rows written with INSERT DELAYED for which some error occurred (probably duplicate key).
Delayed_insert_threads 0 The number of INSERT DELAYED handler threads in use. Every different table on which one uses INSERT DELAYED gets its own thread.
Delayed_writes 0 The number of INSERT DELAYED rows written.
Not_flushed_delayed_rows 0 The number of rows waiting to be written in INSERT DELAY queues.
Begin Key cache Variabelen Waarde Beschrijving
MySQL - Documentatie
Key_blocks_not_flushed 0 The number of key blocks in the key cache that have changed but haven't yet been flushed to disk. It used to be known as Not_flushed_key_blocks.
Key_blocks_unused 84 k The number of unused blocks in the key cache. You can use this value to determine how much of the key cache is in use.
Key_blocks_used 2.162 The number of used blocks in the key cache. This value is a high-water mark that indicates the maximum number of blocks that have ever been in use at one time.
Key_read_requests 40 M The number of requests to read a key block from the cache.
Key_reads 14 k The number of physical reads of a key block from disk. If Key_reads is big, then your key_buffer_size value is probably too small. The cache miss rate can be calculated as Key_reads/Key_read_requests.
Key_write_requests 80 k The number of requests to write a key block to the cache.
Key_writes 43 k The number of physical writes of a key block to disk.
Key_buffer_fraction_% 14,11 %
Begin Joins Variabelen Waarde Beschrijving
Select_full_join 605 The number of joins that do not use indexes. If this value is not 0, you should carefully check the indexes of your tables.
Select_full_range_join 3 The number of joins that used a range search on a reference table.
Select_range 3.323 The number of joins that used ranges on the first table. (It's normally not critical even if this is big.)
Select_range_check 4 The number of joins without keys that check for key usage after each row. (If this is not 0, you should carefully check the indexes of your tables.)
Select_scan 14 k The number of joins that did a full scan of the first table.
Begin Replication Variabelen Waarde Beschrijving
Show slave hosts Show slave status MySQL - Documentatie
Rpl_status NULL The status of failsafe replication (not yet implemented).
Slave_open_temp_tables 0 The number of temporary tables currently open by the slave SQL thread.
Slave_retried_transactions 0 Total (since startup) number of times the replication slave SQL thread has retried transactions.
Slave_running OFF This is ON if this server is a slave that is connected to a master.
Begin Sorting Variabelen Waarde Beschrijving
Sort_merge_passes 1.111 The number of merge passes the sort algorithm has had to do. If this value is large, you should consider increasing the value of the sort_buffer_size system variable.
Sort_range 6.524 The number of sorts that were done with ranges.
Sort_rows 708 k The number of sorted rows.
Sort_scan 5.330 The number of sorts that were done by scanning the table.
Begin Tabellen Variabelen Waarde Beschrijving
Flush (close) all tables Show open tables
Open_tables 264 The number of tables that are open.
Opened_tables 3.237 The number of tables that have been opened. If opened tables is big, your table cache value is probably too small.
Table_locks_immediate 144 k The number of times that a table lock was acquired immediately.
Table_locks_waited 20 The number of times that a table lock could not be acquired 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.

Open_files 480 The number of files that are open.
Open_streams 0 The number of streams that are open (used mainly for logging).
