This MySQL server has been running for 103 days, 23 hours, 21 minutes and 44 seconds. It started up on Sep 14, 2024 at 11:11 PM.

Server traffic: These tables show the network traffic statistics of this MySQL server since its startup.

Query statistics: Since its startup, 120,000,802 queries have been sent to the server.

Begin SQL query

Variable	Value	Description
Flush_commands	145	The number of executed FLUSH statements.
Last_query_cost	0	The total cost of the last compiled query as computed by the query optimizer. 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.
Slow_queries	7	The number of queries that have taken more than long_query_time seconds.

Begin InnoDB

Variable	Value	Description
Variables InnoDB Status
Innodb_buffer_pool_pages_data	1,758	The number of pages containing data (dirty or clean).
Innodb_buffer_pool_bytes_data	29 M
Innodb_buffer_pool_pages_dirty	0	The number of pages currently dirty.
Innodb_buffer_pool_bytes_dirty	0
Innodb_buffer_pool_pages_flushed	92 k	The number of buffer pool pages that have been requested to be flushed.
Innodb_buffer_pool_pages_free	6,431	The number of free pages.
Innodb_buffer_pool_pages_misc	2	The number of pages busy because they have been allocated for administrative overhead such as row locks or the adaptive hash index. This value can also be calculated as Innodb_buffer_pool_pages_total - Innodb_buffer_pool_pages_free - Innodb_buffer_pool_pages_data.
Innodb_buffer_pool_pages_total	8,191	Total size of buffer pool, in pages.
Innodb_buffer_pool_read_ahead_rnd	0	The number of "random" read-aheads InnoDB initiated. This happens when a query is to scan a large portion of a table but in random order.
Innodb_buffer_pool_read_ahead	0
Innodb_buffer_pool_read_ahead_evicted	0
Innodb_buffer_pool_read_requests	54 M	The number of logical read requests InnoDB has done.
Innodb_buffer_pool_reads	971	The number of logical reads that InnoDB could not satisfy from buffer pool and had to do a single-page read.
Innodb_buffer_pool_wait_free	0	Normally, writes to the InnoDB buffer pool happen in the background. However, if it's necessary to read or create a page and no clean pages are available, it's necessary to wait for pages to be flushed first. This counter counts instances of these waits. If the buffer pool size was set properly, this value should be small.
Innodb_buffer_pool_write_requests	25 M	The number writes done to the InnoDB buffer pool.
Innodb_data_fsyncs	8,577	The number of fsync() operations so far.
Innodb_data_pending_fsyncs	0	The current number of pending fsync() operations.

Innodb_data_written	4,344 M	The amount of data written so far, in bytes.
Innodb_dblwr_pages_written	92 k	The number of pages that have been written for doublewrite operations.
Innodb_dblwr_writes	2,023	The number of doublewrite operations that have been performed.
Innodb_have_atomic_builtins	ON
Innodb_log_waits	0	The number of waits we had because log buffer was too small and we had to wait for it to be flushed before continuing.
Innodb_log_write_requests	3,088 k	The number of log write requests.
Innodb_log_writes	4,516	The number of physical writes to the log file.

Begin Handler

Variable	Value	Description
Handler_commit	2,978	The number of internal COMMIT statements.
Handler_delete	306 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_prepare	0
Handler_read_first	19 M	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.
Handler_read_key	20 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_last	3,097 k
Handler_read_next	3,368 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	8,977	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	41 M	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	1,755 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	101	The number of internal ROLLBACK statements.
Handler_savepoint	0
Handler_savepoint_rollback	0
Handler_update	376 k	The number of requests to update a row in a table.
Handler_write	1,696 M	The number of requests to insert a row in a table.

Begin Query cache

Qcache_inserts	20 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	2,352 k	The number of non-cached queries (not cachable, or not cached due to the query_cache_type setting).
Qcache_queries_in_cache	1,557	The number of queries registered in the cache.
Qcache_total_blocks	3,144	The total number of blocks in the query cache.

Begin Threads

Variable	Value	Description
Show processes
Slow_launch_threads	0	The number of threads that have taken more than slow_launch_time seconds to create.
Threads_cached	7	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	1	The number of currently open connections.
Threads_created	5,365	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_%	99.97 %

Begin Binary log

Variable	Value	Description
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

Variable	Value	Description
Created_tmp_disk_tables	2,772 k	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	0	How many temporary files mysqld has created.
Created_tmp_tables	27 M	The number of in-memory temporary tables created automatically by the server while executing statements.

Begin Delayed inserts

Variable	Value	Description
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 DELAYED queues.

Begin Key cache

Variable	Value	Description
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	13 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	4,619	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	6,587 k	The number of requests to read a key block from the cache.
Key_reads	1,294	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	71 k	The number of requests to write a key block to the cache.
Key_writes	37 k	The number of physical writes of a key block to disk.
Key_buffer_fraction_%	20.84 %
Key_write_ratio_%	52.82 %
Key_read_ratio_%	0.02 %

Begin Joins

Variable	Value	Description
Select_full_join	2	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	0	The number of joins that used a range search on a reference table.
Select_range	3,382 k	The number of joins that used ranges on the first table. (It's normally not critical even if this is big.)
Select_range_check	0	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	27 M	The number of joins that did a full scan of the first table.

Begin Replication

Variable	Value	Description
Rpl_status	AUTH_MASTER	The status of failsafe replication (not yet implemented).
Slave_heartbeat_period	0

Slave_received_heartbeats	0
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

Variable	Value	Description
Sort_merge_passes	0	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	44 k	The number of sorts that were done with ranges.
Sort_rows	41 M	The number of sorted rows.
Sort_scan	9,272 k	The number of sorts that were done by scanning the table.

Begin Tables

Variable	Value	Description
Flush (close) all tables Show open tables
Open_tables	91	The number of tables that are open.
Opened_tables	19 k	The number of tables that have been opened. If opened tables is big, your table cache value is probably too small.
Table_locks_immediate	3,517 k	The number of times that a table lock was acquired immediately.
Table_locks_waited	14	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.
